Vacuette Lithium Heparin Tube, 4mL, 13x75mm, 50/Pk

The interior of the tube wall is coated with lithium heparin or sodium heparin. Heparin is an anticoagulant that binds antithrombins, effectively blocking the coagulation cascade producing a plasma sample. Heparin tubes are used for determinations in clinical chemistry and Immunochemistry.

VAGUE lb Plasma Tubes with Lithium Heparin and Gel contain a barrier gel in the tube. During centrifugation, the gel barrier moves upward where it forms a stable barrier separating the plasma from cells. Plasma may be aspirated directly from the collection tube, which eliminates the need for transfer to another container
