IMPROVACUTER® No additive tube is used in blood collection and storage for biochemistry, immunology and serology tests in medical inspection. It can provide enough and unpolluted serum specimen for clinical test, while keeping the serum invariable in the long inspection period. It is applicable for all current mainstream biochemical analyzers.

IMPROVACUTER® Pro-coagulation Tube is used in blood collection and storage for biochemistry and immunology tests. It is coated with micronized silica particles which activate clotting in a comparatively short time. High quality serum can be acquired after centrifugation, meeting the requirement of fast clinic and emergency medicine.

IMPROVACUTER® Gel & clot activator tube is contains a barrier gel that is present in the bottom of the tube.The density of this material causes it to move upward during centrifugation to the serum-clot interface, where it forms a barrier separating serum from fibrin and cells. Serum may be aspirated directly from the collection tube, eliminating the need for transfer to another container.

The interior of the tube wall is coated with lithium heparin or sodium heparin to inhibit clotting. The anticoagulant heparin activates antithrombins, thus blocking the coagulation cascade and producing a whole blood / plasma sample instead of clotted blood and serum.

IMPROVACUTER® ESR Tube (4NC 0.109M)/( 4NC 0.129M) contain a 3.2 % buffered tri-sodium citrate solution (0.109 mol/l).  The mixing ratio is 1 part citrate to 4 parts blood.  IMPROVACUTER® ESR Tube (4NC 0.109M)/( 4NC 0.129M) are used for the collection and transport of venous blood sedimentation rate testing.  ESR measurements refer to the Westergren method.

IMPROVACUTER® Gel & EDTA.K2 tube is a kind of EDTA.K2 tube for a special use: the preparation of undiluted plasma specimen instead of whole blood specimen. There are 2 kinds of additives inside: inert separation gel at the bottom of the tube and EDTA.K2 sprayed in the interior surface above gel.

IMPROVACUTER® EDTA tube  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. The ultrasonic spraying technique is used during the production process, which ensures complete and rapid decentralization of the additive, and thus sufficient mixing with the blood specimen.

IMPROVACUTER® Citrate Tube  concentrations of either 0.109 mol/l (3.2 %) or 0.129 mol/l (3.8 %) are available. The choice of the concentration depends upon the policies of the laboratories. The mixing ratio is 1 part citrate to 9 parts blood. It can provide buffered system and ultrahigh surface energy surface of blood specimen and avoid the activation of blood platelet. It can provide an excellent condition for the test of PT and APTT values.

IMPROVACUTER® Gel & heparin tube is a kind of anti-coagulation tube with inert separation gel at the bottom of heparin tube. Through centrifugation, the separation gel can form a barrier between plasma and blood cell and prevent substance exchange between them, while keeping the original characters of plasma. Plasma specimen obtained is the best choice for electrolyte test, and is also used for plasma analysis in routine biochemistry and any emergent biochemistry. The specimen could be put into the equipment directly and kept stable in cold storage for 48 hours, which favors the specimen retest.

IMPROVACUTER® Glucose Tubes are available with different additives. The tubes contain a stabilizer and an anticoagulant, Sodium Fluoride and Potassium Oxalate or Sodium Fluoride and EDTA. Glucose tubes are suitable for the analysis of blood sugar and lactate.
