heparin tubes are coated on the inside wall with spray-dried lithium, ammonium or sodium heparin and are used to determine analytes in clinical chemistry. The additive acts as an anticoagulant, and blocks the clotting cascade.
heparin separator tubes contain an inert separator gel on the base of the tube which, after centrifugation, forms a stable barrier between the plasma and the blood cells. VACUETTE®
heparin tubes with separator gel improve the plasma yield and allow plasma to be stored in primary tubes.
Our green top heparin blood tubes are primarily used for drawing blood for chemistry and immunochemistry testing. See our available Lithium Heparin tubes, Lithium heparin tubes with gel separator and Sodium Heparin tubes in a variety of sizes and types.
