The Principle of Filtration


As blood flows through the V-PET system, platelets are selectively captured on the surface of the filter through a complex interaction of size exclusion and adsorption, while the majority of red cells pass through. The platelet concentrate is then recovered by back-flushing the filter with a harvest solution.

Filter performance

The system provides a 3x concentration of platelets (PLT) and their associated growth factors, and a 2x concentration of white blood cells (WBC), some of which are stem cells, from 55 mL of the patient’s own blood for use as a cell therapy.
