Two of its most valuable features are the P1 and P2 program keys. A defined setup can be stored and activated when the machine is powered on, reducing repetitive menu adjustments for recurring procedures. The digital controls support both RPM and G-force settings, and the timer covers 30 seconds to 99 minutes or continuous operation. A brushless DC motor, high-quality rotor, ABS casing, cast-iron base, and vacuum suction feet support stable, smooth operation.
Safety provisions are unusually comprehensive for this size of centrifuge. The lid interlock prevents the cover from opening until the rotor stops, an overspeed detector operates during the run, and the lock releases automatically when the cycle ends. The unit also performs an internal self-test at startup and provides a sound alert. These measures make the operating process more predictable, especially in a busy laboratory.
This is a strong all-around recommendation for users who need more than basic speed control but may not require a high-capacity rotor. The main limitation is its six-tube arrangement, which could become restrictive when processing numerous samples simultaneously. Buyers should also confirm that the required adapters and tubes are included for their workflow. For recurring PRP tasks and varied tube sizes, however, its features are exceptionally well balanced.
Flexible Tube Compatibility
The fixed rotor accommodates up to six 15, 10, 7, or 1.5–5 mL tubes with the appropriate adaptors. This flexibility lets one machine cover several collection and centrifugation formats without making the user commit to a single tube standard.
Practical Programming and Safety
Two stored programs speed up repeated workflows, while the interlock, overspeed detector, startup self-test, and automatic lock release work together to reduce avoidable operating risks. These are practical additions for anyone running standardized procedures.

Capacity is its defining advantage. The machine accommodates eight 15 mL tubes and supports 5–10 mL vacuum collection tubes and 10–15 mL centrifuge tubes. The timer can be set from one to 99 minutes or bypassed for continuous running. Importantly, the timer starts only after the selected speed is reached, helping prevent a cycle from counting down during acceleration.
The control display allows users to adjust time, speed, and RCF, making the essential settings easy to review. A lid lock helps protect the operator while reducing noise and air resistance, and the listed operating noise does not exceed 65 dB. Although the machine does not include the same memory-program features as the ONiLAB, its direct LED adjustment scheme keeps routine operation straightforward.
This centrifuge is well suited to facilities that need to process eight samples at once but do not require the highest relative force. The trade-off is that 1880×g is below the 2600×g and 3074×g figures offered by several competitors. Users working with more demanding separation procedures should compare those figures against their validated protocol. For routine low-speed processing, it offers an appealing combination of capacity, rating, and simple controls.
Efficient Batch Processing
Eight 15 mL positions let a laboratory process a larger batch without upgrading to a higher-capacity rotor. The arrangement is particularly practical for recurring sets of vacuum tubes and standard centrifuge tubes.
Timer Begins at Speed
The timer counts only after the centrifuge reaches the selected speed. This design preserves the intended separation time and avoids reducing the effective run simply because the rotor is still accelerating.

We may earn a commission when you buy through this link, at no additional cost to you.
The rotor holds eight 10 or 15 mL centrifuge tubes and eight 2, 5, or 10 mL vacuum collection tubes. The listing specifically warns buyers not to assume compatibility with other sizes if they are unsure. Speed is electronically controlled from 500 to 5000 RPM, and the timing range extends from 10 seconds to 99 minutes and 59 seconds. A momentary centrifugation button provides a quick start while held and stops the run when released.
The intelligent electronic lock prevents premature lid access and opens the lid after the operation ends. A malfunction alarm adds another layer of protection, while the low-speed brake supports quick, effective separation. The one-year limited warranty and stated manufacturer support offer some reassurance for buyers comparing this model with other similarly capable units.
This centrifuge best suits a laboratory that values speed, force, and a robust aluminum rotor over stored programs. Its eight-place capacity is more substantial than most six-position alternatives, and the precise short timing range offers flexibility for brief spins. The main purchasing consideration is tube fit: users should consult the compatibility instructions carefully and confirm the exact tubes and adaptors required for their application.
Separation Power for Demanding Work
A maximum speed of 5000 RPM and force of 3074×g lead the field here. That performance gives protocols more latitude than units limited to 1880×g or 1920×g, particularly when working with denser or more complex samples.
Fast Short-Spin Operation
The instantaneous centrifugation function starts while the button is held and stops when it is released. Combined with a timer beginning at 10 seconds, it provides a practical way to perform quick, controlled spins.

We may earn a commission when you buy through this link, at no additional cost to you.
Its angular rotor accepts an unusual range of formats, including six 50, 15, or 10 mL centrifuge tubes and six 2–5 or 10 mL vacuum tubes. The timer spans 30 seconds to 99 minutes. Wide-voltage technology is designed to resist fluctuations and maintain speed accuracy, while the LCD makes the programmed parameters easier to inspect and adjust.
Protection extends beyond the standard lid lock. The centrifuge automatically cuts power when vibration exceeds a safe threshold, and the manufacturer recommends symmetrically balancing tubes before operation. A ventilated chamber dissipates heat rapidly, helping protect samples from thermal damage. These protections are especially relevant to clinical and laboratory users who need consistent plasma quality and stable equipment behavior.
The LC500-6 is an excellent choice for facilities running standardized plasma protocols that benefit from stored settings. Nine programs remove much of the need to reset speed and time for every batch. The six-tube capacity is modest, but the flexible rotor and dedicated safety systems compensate for that limitation. Users should follow the balance requirement carefully because correct loading remains essential to safe, consistent separation.
Nine Workflow Memory Slots
Nine customizable speed-time combinations let established procedures be recalled without repeated manual setup. This is especially valuable for clinics and laboratories that separate several sample types under different validated conditions.
Vibration and Heat Safeguards
Automatic power cutoff protects the machine if vibration exceeds a safe threshold, while chamber ventilation helps control heat. Together, they support stable operation and sample protection, provided tubes are balanced symmetrically.

The rotor accommodates six 10 mL tubes, while the stated tube range includes both 5 and 10 mL sizes. Speed can be adjusted from 300 to 4000 RPM using stepless buttons, and the timing range extends from zero to 60 hours in five-minute steps. A continuous operating mode is also listed, along with a 50-watt DC motor and a vibration coefficient no greater than 0.6 mm/s.
Its strongest qualities are physical practicality. The high-strength ABS shell offers a durable housing, and the anti-slip feet help the machine remain stable. The listed noise level of no more than 50 dB is the lowest stated figure among these models, making it potentially attractive for quieter workspaces. Stepless controls can also provide more continuous adjustment than a conventional stepped dial.
The trade-offs are its six-tube capacity, limited rotor size, and lack of a published maximum RCF figure. Because the listing does not state maximum relative centrifugal force, users with protocol-specific requirements should seek that information before ordering. For teaching, demonstrations, or small routine batches where portability and simplicity matter most, however, this is a practical and economical compact option.
Compactness for Flexible Workspaces
At just 3.5 pounds, the unit can be moved more easily than larger benchtop centrifuges. Its small footprint is useful for classrooms, shared workspaces, and temporary sample-processing stations.

The speed controls cover zero to 4000 RPM, and the timer extends from zero to 120 minutes or can run continuously. Compatible formats include 5–10 mL vacuum tubes and 10–15 mL centrifuge tubes. The panel presents operating values clearly, while the transparent glass cover lets users observe the rotor and is described as helping reduce noise and air resistance.
Its most obvious advantage is throughput. Twelve tubes in a single run can reduce the number of batches required for teaching laboratories, quality-control settings, and other routine workflows. The 2325×g maximum force also exceeds several models in the group, giving it more separation capability than basic low-speed desktop units.
Potential drawbacks include the stated noise level of no more than 70 dB, which is the highest published figure here, and the use of a glass cover that may make the unit less convenient to carry. Its lower user rating may also make prospective buyers want to examine customer feedback more closely. Nevertheless, for users who prioritize twelve-tube capacity and broad timer settings, the 80-2 delivers a functional combination.
Twelve Tubes per Batch
The twelve-position rotor is the largest capacity listed among the reviewed machines. It can help laboratories and teaching facilities complete more samples per cycle without immediately moving to a larger floor model.
Wide Timing and Force
A timer range of zero to 120 minutes and a maximum force of 2325×g provide useful control for varied routines. The trade-off is a listed noise level as high as 70 dB.

We may earn a commission when you buy through this link, at no additional cost to you.
The rotor supports up to six 15 mL centrifuge tubes or 10 mL test tubes. The manufacturer notes that a similar product includes adapters for 5 and 7 mL tubes, so users needing those sizes should verify the appropriate holder configuration. The LCD displays time and speed across a 20-second to 99-minute timer, with actual speed calculated at ten times the upper-right displayed value.
That display convention deserves attention during setup. Rather than expecting the visible number to represent the full RPM value, the operator must interpret the upper-right panel indicator. The dedicated short-spin control simplifies quick spins, while the safety lid lock prevents opening until the rotor has stopped and releases automatically after the run. The unit uses 110-volt, 60-hertz power and is rated at 40 watts.
This centrifuge is best for users who value maximum force and a short-spin function in a relatively compact six-tube format. Its limitations are the modest capacity and the need to understand the speed-display arrangement. A one-year warranty and US-based professional customer support are useful additions. Buyers should check tube holders carefully, especially when working with smaller sample formats.
High Force in a Compact Form
The 3074×g maximum matches the highest figure among the products reviewed, yet the rotor remains limited to six tubes. It offers a useful middle ground for protocols needing force more than capacity.
Convenient Short-Spin Button
A separate short-spin control allows quick routines without navigating the full timer. The lid-lock system and automatic release help maintain safe access while preserving this convenience.

The LCD gives direct access to speed, time, and RCF settings, which is useful for teaching laboratories, routine chemistry work, quality-control checks, and various industrial applications. The high-strength ABS housing has a matte finish intended to resist aging, while the polycarbonate observation window allows monitoring of the speed, reduces noise, and helps keep dust out of the chamber.
Its safety design is particularly comprehensive. Lid-open protection stops the rotor immediately, overspeed protection guards against excessive speed, and automatic fault alerts signal abnormal conditions. A mechanical door latch can open the lid during a power outage. Stability is supported by rubber suction feet, a brushless DC motor, and precision bearings, all intended to reduce wobble during faster runs.
The trade-off is performance relative to the premium high-force models. Its 1920×g maximum is lower than the 2146×g, 2600×g, and 3074×g offered by several alternatives. Nonetheless, it has a capable eight-tube rotor, a precise timer, and one of the strongest safety descriptions in the group. It is a sound general laboratory choice when safety features and straightforward operation are priorities.
Layered Protection Features
Immediate lid-open stopping, overspeed protection, and automatic fault alerts provide several layers of operational control. A mechanical release also preserves access if electrical power is unavailable.
Stable Anti-Vibration Design
Rubber suction feet, precision bearings, and a brushless motor help minimize wobble. A clean, smooth bench surface is important because the feet rely on suction to remain firmly attached.

Two program memory keys allow users to customize speed-and-time settings. The stored program can run automatically when the plasma centrifuge starts, which reduces setup time for recurring procedures. Its LCD provides real-time visibility of the control settings, while the included A6-15P fixed-angle rotor and adaptors accommodate 15, 10, 7, and 1.5–5 mL tubes.
The weighted base is designed to limit vibration in field environments, and a brushless DC motor supports smooth, quiet operation with a listed noise level no greater than 56 dB. Safety systems include a lid interlock, overspeed detector, automatic lock release after the rotor stops, and an internal self-test performed at startup.
This model is a balanced recommendation for users who want programmable PRP handling without moving to a higher-capacity unit. Its principal limitation is the six-tube rotor, and buyers should carefully distinguish its included tube configuration from other options. No warranty duration is stated in the supplied product information. Even so, the combination of flexible adapters, stored programs, stable base, and quiet motor makes it a practical choice for recurring laboratory procedures.
Recurring Program Automation
P1 and P2 store customized procedures and can launch them automatically. The feature is particularly useful when alternating between two established sample-processing routines.
Stable and Quiet Operation
A weighted base helps reduce movement, while the brushless motor operates at no more than 56 dB. These characteristics suit shared benches and environments where stability and moderate sound levels matter.

Buying Guide – How to Choose the Best Centrifuge
The best centrifuge is the one that safely supports your approved workflow with compatible tubes, suitable force, repeatable controls, and enough capacity for routine batches. Rather than comparing only maximum speed, buyers should evaluate the complete operating system and the demands of their samples.
Rotor Capacity and Tube Fit
Rotor capacity determines how many samples can be processed in one cycle, but the number of positions is only useful when each position accepts the tubes required by the application. The reviewed models range from six to twelve positions, with advertised tube formats extending from 2 and 5 mL collection tubes to 20 and 50 mL centrifuge tubes. Match the tube diameter, length, material, and rated speed with the rotor specification rather than relying on volume alone.
Also confirm whether adapters are included and whether a listed tube size requires a separate holder. The LAB FISH, ONiLAB, and Utile models use adapters for several smaller formats, while the Microyn listing points buyers toward a similar model with 5 and 7 mL adapters. Correct tube-to-rotor fit is essential for balanced loading and dependable separation.
Speed and Relative Centrifugal Force
RPM describes rotational speed, while RCF expresses the force acting on a sample. Two machines at the same RPM can produce different forces because rotor radius and tube position matter. Published maximum RCF values here range from 1880×g to 3074×g, and one compact model does not publish a maximum force figure. Protocol-specific users should use RCF as the more relevant comparison when available.
A higher maximum number does not automatically make a machine better. Choose a range that covers the validated procedure without encouraging unnecessary speed. The LC500-6, LAB FISH, and Microyn provide the highest stated force, while the ONiLAB and Utile reach 2600×g. Lower-speed models may be fully sufficient for routine qualitative analysis, teaching, or plasma preparation.
Timer Range and Cycle Modes
Timer flexibility determines whether a machine can handle very short spins, standard separations, and extended procedures. The reviewed ranges vary considerably: the NEWTRY extends to 60 hours, the CGOLDENWALL 80-2 reaches 120 minutes, and several models support timing to 99 minutes and 59 seconds. Most also offer continuous operation. A timer that starts only after the set speed is reached, as described for the CGOLDENWALL PRP model, can provide more consistent effective cycle times.
For recurring work, consider how quickly a procedure can be repeated. A separate short-spin button on the Microyn and a momentary function on the LAB FISH support quick interventions. For standardized workflows, stored speed-and-time combinations on the ONiLAB, Utile, and LC500-6 are more valuable than a long timer without programmability.
Programming and Controls
Controls should make speed, time, and force easy to enter and verify. An LED or LCD display reduces uncertainty, especially when a protocol depends on a particular RCF. Some machines display all three values directly, while the Microyn uses a panel convention in which the actual speed is the upper-right displayed value multiplied by ten. Buyers should confirm how the readout is presented before operating a unfamiliar unit.
Program memory is useful when several procedures are standard. The LC500-6 stores nine combinations, while the ONiLAB and Utile each provide two programmable keys. Models without stored programs can still be effective for one-off or variable tasks, but they may require more manual input each time. Choose a control layout that matches the complexity and repeatability of the workload.
Safety and Sample Protection
A lid interlock is a fundamental feature because it prevents access while the rotor is moving. Automatic release after a completed cycle improves convenience, while overspeed detection, startup self-tests, fault alerts, and vibration-based power cutoff add further protection. The LCD 8x10ml/15ml model combines immediate lid-open stopping with overspeed protection, fault alerts, and a mechanical release for power outages.
Temperature management also matters for sensitive samples. The LC500-6 includes chamber ventilation intended to dissipate heat and protect samples, while the ONiLAB and Utile emphasize quieter motor operation. None of these features replaces correct loading. Tubes should be balanced symmetrically, the rotor should remain within its rated limits, and laboratory procedures should govern the final operating settings.
Noise, Stability, and Footprint
A centrifuge that shakes, drifts, or produces excessive noise can make small workspaces frustrating and may indicate poor load balance. The NEWTRY lists noise at no more than 50 dB, while the ONiLAB and Utile state levels no greater than 56 dB. The CGOLDENWALL 80-2 is rated as high as 70 dB, which may be less desirable in shared rooms.
Stability comes from the base, feet, rotor construction, and correctly balanced tubes. The Utile uses a weighted base, the ONiLAB adds vacuum suction feet and a cast-iron base, and the LCD model uses rubber suction feet. Compact dimensions are especially helpful when bench space is limited, but buyers should also consider room for lid access, tube insertion, ventilation, and safe movement around the machine.
Motor and Rotor Construction
Motor design influences smoothness, maintenance requirements, noise, and operating consistency. Brushless DC motors appear in the ONiLAB, LAB FISH, Utile, and LCD models, while the NEWTRY also lists a DC motor. The LAB FISH is the only reviewed unit that explicitly identifies its fixed-angle rotor as aluminum alloy, and the ONiLAB describes a high-quality rotor with a cast-iron base.
These construction claims should be considered alongside capacity and force. A premium motor does not compensate for incompatible tubes, and a large rotor does not necessarily provide better speed regulation. Select a combination that fits the physical workload and offers the features needed for repeatable operation rather than choosing on material alone.
Intended Application
Different descriptions point to different use cases. The ONiLAB, Utile, and LC500-6 specifically emphasize PRP, PRF, or plasma work, while the CGOLDENWALL models reference hospital, biochemical, qualitative, and serum or plasma separation. The SUPER DEAL lists medical, laboratory, production, office, and classroom uses, and the NEWTRY prioritizes portable routine operation.
Application descriptions are useful for forming a shortlist but do not establish clinical validation or suitability for every protocol. Buyers should check institutional requirements, sample types, rotor ratings, and any applicable professional guidance. The final choice should satisfy the validated procedure and local operating requirements, not merely the broadest marketing description.
How to Use and Care for Your Centrifuge
Begin by confirming that the rotor, adapters, tubes, and lid are correct for the procedure. Inspect tubes for damage, cap closure, cracks, leaks, and correct fill level, then place them in opposing positions with balanced volumes and weights. Do not use unapproved tube sizes or rotor configurations. Close the lid fully and verify that the interlock has engaged before starting the rotor.
Set the required time, speed, and, where available, RCF using a validated protocol rather than selecting the maximum simply to finish quickly. If the machine offers stored programs, confirm that the recalled settings match the intended procedure. Allow the rotor to accelerate fully, watch for unusual vibration, and never reach into or force open the chamber while the rotor is moving. Use the short-spin control only for procedures designed for brief spins.
After the cycle, wait for the rotor to stop and for the automatic lid release to operate. Remove balanced tubes carefully, inspect the separated material, and clean the rotor, chamber, and exterior according to the manufacturer’s instructions. Keep the bench clean so suction feet can maintain stability, avoid blocking ventilation, disconnect the unit safely when cleaning, and investigate persistent vibration, unusual sound, temperature changes, or error alerts before another run.
Frequently Asked Questions
What is the difference between RPM and RCF in a centrifuge?
RPM measures how quickly the rotor turns, while RCF estimates the centrifugal force applied to a sample. Because RCF depends on rotor radius as well as speed, two centrifuges with the same RPM can produce different forces. Use the force specified by your procedure when available, and verify the tube position if a protocol calls for a particular RCF value.
Which centrifuge is best for routine PRP sample preparation?
The ONiLAB, Utile, and LC500-6 are the most directly oriented toward PRP, PRF, or plasma preparation. The ONiLAB and Utile offer two stored programs with a 2600×g maximum, while the LC500-6 provides nine programs and a 2146×g maximum. The best choice depends on tube formats, batch size, and the validated settings required by your facility.
How many tubes can these benchtop centrifuges hold?
Capacities in this roundup range from six to twelve tubes per run. The CGOLDENWALL 80-2 has the largest stated rotor at twelve positions, while the CGOLDENWALL PRP, LAB FISH, and LCD 8x10ml/15ml models each hold eight. The remaining selections use six-position rotors, so batch requirements may influence the final choice.
Can I use smaller tubes with a larger-tube rotor?
Only when the manufacturer confirms that the correct adapter or holder is available and approved. A tube fitting inside a rotor opening does not automatically mean it is safe or balanced. Check tube diameter, length, shape, material, and speed rating, and use the specific adapter identified in the product instructions.
Why does a centrifuge vibrate during a run?
Unbalanced tubes, incorrectly seated adapters, residue on the rotor, damaged tubes, or a loose surface can all contribute to vibration. Stop the machine if vibration becomes severe, then inspect loading and repeat the run with symmetrically balanced tubes. Models such as the LC500-6 and LCD 8x10ml/15ml include vibration-related protection, but correct loading remains essential.
Is a higher maximum RPM always better?
No. A suitable centrifuge must meet the force and tube requirements of the validated method while remaining stable and easy to operate. A machine offering 5000 RPM may be unnecessary for routine work, while a lower-speed model may be entirely appropriate for simple separations. Capacity, controls, safety, and sample protection often matter more than the largest headline number.
What maintenance does a benchtop centrifuge need?
Keep the chamber, rotor, and lid clean, inspect tubes and adapters regularly, and follow the manufacturer’s cleaning instructions. Use suitable disinfectants only where approved, and never spray liquid into controls or ventilation openings. Do not operate the unit with a damaged lid, unbalanced rotor, cracked tube, or obstructed cooling path.
Can the same centrifuge handle continuous operation?
Most of the reviewed models offer a continuous mode in addition to timed runs. Continuous operation still requires balanced loading, appropriate tube ratings, and monitoring. The timer-beginning behavior and automatic lid release differ among models, so operators should follow the specific manual and laboratory procedure for the unit in use.
Final Thoughts on Choosing the Best Centrifuge
The ONiLAB Lab PRP Centrifuge stands out as the best overall choice because it combines 2600×g of force, flexible tube adapters, two stored programs, and a comprehensive safety system. The LAB FISH LC-8S leads the high-performance side with 5000 RPM, 3074×g, and an aluminum alloy rotor, while the LC500-6 is especially attractive for plasma workflows that benefit from nine programmed settings.
For buyers prioritizing affordability and portability, the NEWTRY Mini Centrifuge is compact, quiet, and simple, although its six-position rotor and unpublished maximum RCF deserve attention. Larger laboratories may prefer the CGOLDENWALL 80-2 for twelve-tube batches, while the CGOLDENWALL PRP model and LCD 8x10ml/15ml model offer useful eight-position alternatives. Prioritize tube fit, force, balanced capacity, controls, and protection rather than relying on speed alone.
Before ordering, verify the current listing specifications, included accessories, rotor and tube approvals, warranty terms, electrical requirements, and intended application. Product details and availability can change, and the correct centrifuge is ultimately the one that supports your validated procedure safely and repeatably.
