Lithium Heparin with Gel Tube 

PSGT Tube stands to Lithium Heparin with Gel Tube. It is coated with lithium heparin, and the inert separation gel is at the bottom of heparin tube. Through centrifugation, the separation gel can form a barrier between plasma and blood cell and prevent substance exchange. Plasma specimen obtained is the best choice for electrolyte test and plasma analysis in routine biochemistry and any emergent biochemistry.
