The PCV-6000 is a versatile and efficient variable-speed centrifugal vortex mixer with compact construction and high cost-effectiveness. Programmable centrifugation and mixing operations are suitable for centrifugation and vortex mixing of multiple microtubes and 0.2 ml co-tubes. Using the rotate-mix-rotate technology, the sample processing cycle is automatically programmed to process up to 12 tubes at the same time, which greatly saves time and eliminates the need to transfer to other equipment for vortex oscillation after each centrifugation.
