A plasma gel separation capillary tube provides the precision of glass with the safety provided by a Mylar over-wrap. Ideal for isolating plasma in small animal studies since the amount of blood extracted is significantly reduced (up to 70 microliters).

 

Placed within the tube’s ID is a small amount of thixotropic gel, which has a specific gravity between that of plasma and the cellular components of whole blood.  The plasma gel migrates during centrifugation between blood and plasma forming a barrier for easily dispensing the full amount of pure plasma.
