Acti-Fine vacuum tubes for venous blood sampling with

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 Acti-Fine plasma tube is used for biochemical tests and rapid diagnostics due to the absence of waiting up to 30 minutes for clot formation. Fully threaded screw thread on the cap and on the tube to avoid spillage of material during transport, mixing and centrifugation, as well as for repeated opening and closing of the tube without splashing the material, to avoid the risk of contamination.
