Description
Separation is a physical argument, and a centrifuge is the bench that settles it. Every protocol that depends on plasma, serum, or a clean cell pellet stands or falls on whether the instrument can hold a rotor speed long enough and steadily enough for density to do its work. The Serum Bench is built by JOANLAB, a manufacturer whose catalogue begins with magnetic stirrers and pipettes and ends with the instruments a working laboratory actually replaces least often.
The drive is a stepless system spanning 500 to 5000 revolutions per minute, with the LCD reporting both RPM and relative centrifugal force so the operator is not converting between the two by hand mid-protocol. Acceleration accuracy holds within plus or minus 30 revolutions per minute, and the timer runs from ten seconds to ninety-nine minutes and fifty-nine seconds, which covers short spins for cell washing as well as the longer cycles PRP preparation demands. Peak RCF reaches 3074 times gravity, sufficient for platelet concentration and serum separation without forcing the sample into a profile that damages it. Three rotor options are offered - six, eight, or twelve positions accommodating 15 millilitre conical tubes or 5 and 10 millilitre blood collection tubes - so one instrument serves a small clinic and a research bench with the same footprint.
Safety and repeatability are handled in the hardware rather than the operator's memory. A lid-lock interlock prevents the rotor from spinning unless the chamber is sealed, and the lid releases automatically when the cycle ends, which removes the most common source of operator error on a shared bench. Noise stays at or below 60 decibels, roughly the level of ordinary conversation, so the instrument can run in a treatment room without dominating it. The chassis measures 375 by 320 by 240 millimetres and weighs 6.5 kilograms, drawing 130 watts from a 110 or 220 volt supply - light enough to move between benches, heavy enough to stay where it is put. The housing is finished in laboratory white with a clear polycarbonate lid, and every unit ships CE certified with a calibration card.
Density does the work. The instrument only has to be honest about the time.

Where It Belongs
This is the instrument that a PRP or aesthetic clinic runs between treatments, separating platelet-rich plasma from whole blood in the small volumes a single patient session produces. In a veterinary practice it prepares serum for in-house panels without sending samples out and waiting a day. Research laboratories use the twelve-position rotor for cell washing and pelleting across a batch of cultures, and the six-position version for protocol development where only a few tubes run at a time. Clinical and cosmetic training schools keep one on the bench because the automatic lid release and the interlock make it forgiving for students. Because it weighs under seven kilograms and draws only 130 watts, it also suits mobile phlebotomy services and field clinics that work from a converted van with a modest inverter supply. Anywhere a protocol specifies a force in times gravity rather than a speed in revolutions, this is the class of instrument that can honour it.
Frequently Asked Questions
Q: Can it run PRP protocols?
A: Yes. The instrument reaches 3074 times gravity at peak, which is within the range used for platelet-rich plasma separation, and the stepless speed control plus the RPM and RCF readout let you hold the exact setting your protocol specifies.
Q: Which rotor should I order?
A: Choose LC-6S for small-volume work and protocol development, LC-8S where you routinely run a batch of eight tubes, and LC-12S when the workload is blood collection tubes at 5 or 10 millilitres. All three accept 15 millilitre conical tubes where the rotor size allows.
Q: Is the lid safe to operate?
A: The chamber cannot spin unless the lid is locked, which is enforced in hardware rather than by a warning label. When the cycle ends the lid releases automatically, so there is no lever to force while a rotor is still moving.
Q: Does it need a dedicated power supply?
A: No. It draws 130 watts from a standard 110 or 220 volt wall outlet at 50 hertz. That is roughly the draw of a domestic appliance, so no special circuit is required.
Q: How loud is it in a treatment room?
A: Measured noise stays at or below 60 decibels, comparable to normal conversation. It can run in a treatment room, a small clinic, or a teaching laboratory without disrupting the people in it.
Q: What is supplied with the unit?
A: The centrifuge ships with its rotor, a power lead matched to your region, and a calibration card. Tubes are not included, because the correct tube depends on the protocol and we would rather you choose the consumable than receive the wrong one.
The EastSupplier Promise
Every unit ships from our overseas warehouse network after a hands-on inspection pass. We verify the plug type, count the parts, and confirm the unit powers on before it leaves the shelf. If a component arrives damaged, our support team responds within one business day with a replacement or a refund - not a script. We have supplied industrial buyers, workshops, and distributors since 2010, and the same standard applies to a single order as to a pallet.
