The Use of EDTA
Performance of EDTA anticoagulant tube Steady roof EDTA anticoagulant tube vacuum blood vessel collection, blood vessel collection, disposable vacuum blood vessel collection, EDTA anticoagulant tube
1. Use of EDTA anticoagulant tube for vacuum blood vessel collection: It is used for clinical hematology test and suitable for various types of blood cell analysis. The inner wall of the blood vessel was sprayed with anti-hanging agents, and anticoagulant was added at the same time. EDTA anticoagulant has little effect on the agglutination of blood cells and cell morphology, and can inhibit platelet aggregation. Vascular harvesting is widely used in clinical hematology examination and suitable for various blood cell analyzers. It provides a comprehensive and meticulous protection scheme for blood cells, especially the use of biomimetic membrane treatment technology to effectively prevent platelet aggregation and activation, prevent coagulation, and protect the shape and volume of blood cells in a longer period of time.

2. Specification and characteristics of disposable vacuum blood collection: color standard: purple specification: 12 *75 mm 12 *100 mm routine blood collection: 2 ml 3 ml 4 ml 5 ml additives: EDTA-K2, EDTA-K3 operating environment temperature: 0-37 C material: glass maximum vacuum error (+10%).
3. Notices for vacuum blood vessel harvesting:
1. Immediately after blood collection, 180 degrees were gently inverted and blended for 5-6 times.
2. When collecting blood, please take enough blood to ensure the accuracy of the test results.
3. Remaining vacuum in the tube should be cleared if the blood collection can not reach the prescribed amount.

[Product Name] Serum Separting Gel
General Name: Serum Separation Gum (Irradiation Resistant)
[Specification] 20KG/barrel, 25KG/barrel
[Product performance] The product is colourless transparent colloid with light odor and no impurities, is physiological inert, insoluble in water, with relative weight of 1.045-1.065g/cm3, viscosity of 10-300,000 cpa, volatile matter less than 1.5%, and has excellent thixotropy and isolation performance. Other properties are detailed in the product test report.
[Scope of application] This product is specially used to manufacture disposable vacuum blood vessel harvesting and injection blood vessel harvesting, as a necessary material for the preparation of high-quality serum and blood samples for preservation, transmission and transfer in clinical tests.
[Notes]
The company's separating glue is a patent product with unique ingredients. Please do not mix it with other suppliers'products, so as not to cause product defects and unnecessary losses to you.
The recommended temperature range for separating gel is - 20 ~90 C. With the change of ambient temperature, the viscosity of the product will change greatly. Low ambient temperature may cause difficulty in gluing. It is suggested that when the ambient temperature is below 15 C, the water bath can be heated to 60 - 70 C to reduce the viscosity and improve the gluing efficiency.
The phenomenon of "drawing" occurs during normal temperature gluing, which can increase the gluing temperature appropriately or break the filament by vibration.
After high vacuum treatment, there is almost no air inclusion in the colloid. It is not recommended to mix in the process of transferring and adding glue, because mixing easily leads to a large amount of air in the colloid.
After adding the product into the test tube, the gel plane flow distance is less than 5 mm after 20 days of inverted test at 60 C in vacuum. It can ensure that no more than 5 mm flow will occur during 20 days of continuous transportation at 60 C by containers, and it will not affect the normal use of blood vessels. Even so, we still recommend that during the long transport process, the blood vessels with separating gel should not be inverted.
It is recommended not to touch the separating glue directly by hand. When adhering to the skin, you can scrape off most of the colloids with clean iron sheets, wipe off most of the colloids with waste newspapers, then clean them with DMC, D4 and other organic solvents, or clean them with detergent powder mixed with sawdust and detergent, and then rinse them with water.
Heparin lithium
Heparin lithium product details:
[Heparin lithium properties] White amorphous powder, odorless, soluble in water, easy to absorb lakes, average molecular weight of 15 000, stable at room temperature.
[DeSheng Heparin Lithium Packaging] 10g/bottle, 50g/bottle (can be subpacked according to customer needs)
[Lithium potency of deshenheparin] 150 IU/mg-180 IU/mg
[Heparin lithium use] This product is specially used for anticoagulation of blood in vitro. It is an anticoagulant additive for clinical blood test. It is used for pretreatment of blood samples (anticoagulant treatment) in the process of clinical blood collection and test.
Heparin lithium is a chemical with a white to white-like appearance. There was no significant difference between heparin lithium anticoagulant plasma and serum TP, ASO, UA, ALT, Mg, Cl, TC, CRP (P > 0.05). There were significant differences in the results of HBD, LDH and TBA between heparin lithium anticoagulant plasma and serum (P < 0.05). Therefore, besides HBD, LDH and TBA, there is a good correlation between heparin lithium anticoagulant plasma and serum. Therefore, it is feasible to use lithium heparin anticoagulant plasma instead of serum in life test, and it can be used as an important detection method.
Commonly used glycin anticoagulant, sodium, potassium, lithium, ammonium salt of glycin, is anticoagulant, but the binding ion is different, the dissociation degree is different, among which heparin lithium is better!
