2.Clot Activator Tube:It is used in blood collection and storage for quik serum measurement and immunology tests. Its main merit is that it's suitable for a wide range of operation, fast in coagulation, and free from both secondary separation of fibrin protein and the cracking of blood corpuscle. Hence the serum can meet the requirements of fast clinic and emergency medicine.

3.Gel tube: It is used for clinical biochemistry and immunology. Inside the tube there is a barrier gel resent at the bottom, which is a pure substance, very stable in physical and chemical features. Even under a high temperature as 90℃,the barrier will not change inside at all. After centrifugation, the barrier can effectively separate the serum from fibrin and cells, while preventing substance exchange between blood cell and serum. As a result, it can keep biochemical characters and chemical components of serum unchanged for a long time. Serum can also be aspirated directly from the collection tube, no need for transfer to another container.

4.Glucose Tube: It used in blood collection and anticoagulation for the analyses such as blood sugar, sugar tolerance, anti-alkali haemoglobin and sugar water.It is available with different additives,sodium fluoride/potassium oxalate/K2EDTA.Owing to the first use of special stabilizer and surface treatment inside the tube,C.D.RICH glucose tube successfully solves the unavoidable hemolysis and prevents the occurrence of insoluble and anti-coagulant substances.So it can guarantee that value of blld sugar can be kept invariable within 72 hours.

5.PT Tubes: It is mainy used for the test of blood coagulation mechanisam.It is filled with citrate concentrations of either 0.109mol/1(3.2%) or 0.129mol/l(3.8%) available.The choice of the concentration depends upon the policies of the laboratories.The mixing ratio is 1 part citrate to 9 parts blood with the advantage of high accurate blood-to-additive ratio. It can provide an excellent condition for the test of PT AND APTT values.

6.Heparin Tube: It is used in blood collection and anti-coagulation not only for routine clinical biochemistry tests and emergency biochemistry tests but also for some test items in blood rheology. It is coated with lithium or sodium heparin. The anticoagulant heparin activates antithrombins, thus blocking the coagulation cascade and producing a whole blood/plasma sample instead of clotted blood plus serum.C.D.RICH validates that through its special treatment, most of the plasma indexs can be repeated within 6 hours, especially for such sensitive ones as AST,ALT,TBIL,DBIL and GGT.

7.EDTA Tube: It is widely used in clinical haematology as well as various kinds of blood cell test instruments. It makes use of EDTA2/EDTAK3 as anticoagulant. Meanwhile, it offers a comprehensive protection for blood cell, especially for protecting the blood platelet, so that it can effectively stop the gathering of blood platelet and makes the form and volume of blood cell uninfluenced in a long time. EDTA tube can be used in direct sampling analyzers without actually being opened.

8.ESR Tube:It is used in blood collection and anticoagulation for sedimentation rate test. It contains a 3.8/% buffered tri-sodium citrate solution(0.129mol/l)with the mixing ratio of 1 part citrate solution to 4 parts blood. ESR measurement refers to the Westergren method.
