Vacuum tubes "Acti-Fine" for venous blood sampling with lithium heparin gel, size 13x75 mm, volume: 1,0 ml.

Acti-Fine plasma vacuum tubes contain heparin salts applied to the inner walls of the tube (heparin concentration 12-30 IU/1 ml of blood).The use of heparin as an anticoagulant activates antithrombins, blocking the clotting cascade in the blood sample.The use of tubes with a separating gel is useful to ensure a stable barrier between the formational elements and plasma after centrifugation.The Acti-Fine tube for obtaining plasma is used for biochemical studies and rapid diagnostics, due to the absence of the need to wait up to 30 minutes for clot formation. In addition, the volume of the obtained sample is larger in the case of plasma. Fully threaded screw threads on the cap and on the tube to avoid material spillage during transport...
