Plasma Separation Gel Tube (PSGT)
Ampulab Plasma tubes with gel contain spray-coated lithium heparin and a polymer gel in the bottom for plasma separation. The specific gravity of this material can make the barrier gel move upward to the plasma - clot interface during centrifugation and it forms a stable barrier separating the plasma from cells.
Samples processed in these tubes are used for plasma determinations in chemistry. Those tubes provide the convenience of gel separation with the added advantage of
improved turnaround time.
