Plasma Vacuum Blood Collection Tube

▶Heparin tubes are coated with spray-dried lithium heparin or sodium heparin, They are used for collecting blood specimen for biochemistry tests and some test items in blood rheology.The anti- coagulants heparin activates anti-thrombins,thus blocking the coagulation cascade of the blood specimen producing a whole blood/plasma sample instead of clotted blood plus serum.

▶Coagulation tubes are filled with a buffered sodium citrate solution.They are available with a citrate concentration of 0.109mol/1(3.2%)or 0. 129mol/l(3.8%).Coagulation tubes are mainly used for examination of coagulation parameters and can provide an excellent condition for the test of PT,APTT VALUES. Coagulation Tube with Sandwich Material consists of inner tube made of PP and outer tube made of PET.Inner tube made of PP can avoid the additive decrease ,which maintains the concentration of sodium citrate stable.Outer tube mabe of PET can guarantee vacuum stable for long time.

▶The additive of glucose tubes are sodium fluoride/potassium oxalate or EDTA/Sodium Fluoride. These tubes are used for glucose determinations.
