PRP Centrifuges for Aesthetic Medicine

PRP (platelet-rich plasma) centrifuges have grown quickly in aesthetic and regenerative medicine. The principle is simple: blood components differ in density, so centrifugation separates red cells, platelet-rich plasma and platelet-poor plasma into layers, and the platelet-rich middle layer is taken for further preparation.

Two spins, not one

PRP preparation usually requires two spins — the biggest difference from routine clinical separation.

The first is a separation spin at lower speed and shorter time, letting red cells settle while plasma stays on top. The second is a concentration spin: transfer the upper plasma to another tube and use higher speed and longer time to pellet the platelets, then discard a proportion of the platelet-poor supernatant to obtain concentrated PRP.

The key to both spins is a flat, clearly defined interface. If the layers are uneven, red cells come along when you draw off the layer, directly compromising the final product.

Four parameters to check

First, the adjustable speed range and its precision.PRP protocols usually need lower speeds than routine high-speed centrifugation, but demand more stability and repeatability at the low end — the same sample should give a consistent layering result from run to run.

Second, the rotor type.A swing-out rotor is recommended: the buckets swing level, the tube sits perpendicular to the axis and the interface is a horizontal line. With an angle rotor the interface is slanted and layers mix easily when drawing off. This is often overlooked when selecting.

Third, tube compatibility.PRP preparation often uses dedicated single-use tubes with diameters and lengths that differ from standard tubes, so confirm the buckets can take them and that adapters exist. Tube material matters too: PP and PC differ in clarity and centrifugation resistance.

Fourth, whether temperature control is needed.Blood samples are temperature-sensitive; if the preparation environment fluctuates or the protocol requires a constant temperature, choose a refrigerated model.

On the word "dedicated"

Many units are marketed as "PRP-dedicated", but the real differences come down to three things: preset programs (the speed and time of both spins on one-touch keys), matched consumables (dedicated preparation tubes and kits) and the operator interface. In principle it is still a low- or medium-speed centrifuge in a particular application configuration.

So do not select by name — go back to the process: does the speed cover both spins, is it a swing-out rotor, does it take your preparation tubes, and is temperature control required. If all four fit, a standard model with the right rotor will do the job.

Compliance note

PRP involves medical procedures, and the equipment is only one link in the chain. Sterile control during preparation, consumable qualification, operator credentials and indication scope are all governed by the regulations applicable to the medical institution in its jurisdiction. Equipment selection does not substitute for these compliance steps.

To confirm speed, rotor and tube configuration for a specific protocol, our engineers will check each item against your tube specification and target layering — there is no universal answer here; it must be matched to the actual consumables.
