No Additive tubes do not contain any additives. They are used for collecting and sorting blood specimen for biochemistry, immunology and serology tests in medical inspection and applicable for all current mainstream biochemical analyzers.
Clot Activator tubes are coated with clot activator on the inner wall of the tubes. They are used for serum determinations in chemistry. Samples processed in these tubes may be used for routine blood donor screening, immunohematology, and diagnostic testing of serum for infectious disease.
Gel Tubes are coated with clot activator and gel for serum separation. They are used for serum determinations in chemistry. They are used for clinical biochemistry and immunology.
The obvious characteristic of Gel Tube is used to obtain high-quality plasma specimen for medical laboratories.
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 anticoagulants 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
The additive of glucose tubes are sodium fluoride/potassium oxalate or EDTA/Sodium Fluoride. These tubes are used for glucose determinations.
Coagulation tubes are filled with a buffered sodium citrate solution. They are available with a citrate concentration of 0.109mol/l(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.
EDTA tubes are coated with EDTA-K2 or EDTA-K3. They are for the examination of whole blood in haematology and can be used in direct sampling analyzers without actually being opened. EDTA bind the calcium ions and therefore blocks the coagulation cascade. Erythrocytes, leukocytes and thrombocytes in an EDTA anticoagulated blood sample are stable for up to 24 hours.
ESR tubes contain a 3.8% buffered tri-sodium citrate solution (0.129mol/l) with the mixing ratio of 1 part citrate solution to 4 parts blood. They are used for blood collection and anticoagulation for sedimentation rate test.
ESR 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 made of PET can guarantee vacuum stable for long time.
