Preparation Of Serum Separating Gel

Packaging specification: 25kg/drum (other packaging can also be customized, need to communicate with the sales manager in advance) Appearance: transparent, translucent, opaque colloid Properties: Physiologically inert, insoluble in water Specific gravity: 1.045-1.065g/cm�³ Viscosity: 10-300,000 cps Volatile matter: â?¤1.5% Validity: Two years Storage conditions: sealed at room temperature (0-40�°C), avoid direct exposure to air and sunlight Reminder: When it is found that there are impurities and foreign substances in the serum separation gel, abnormal smell, abnormal color and expired expiration date, it is recommended not to use.

[product name]General name: serum separating gel (radiation resistant) [Specification] 20kg / barrel, 25kg / barrel [product performance] the product is colorless and transparent colloid with light smell and no impurities; it is physiologically inert and insoluble in water, with a relative specific gravity of 1.045-1.065g/cm3, a viscosity of 100000-300000 centipa, and a volatile content of â?¤ 1.5%. It has excellent thixotropic and isolation properties. See the product test report for other properties. [scope of application] this product is specially used for manufacturing disposable vacuum blood collection vessels and injection blood collection vessels, as the necessary materials for the storage, transmission and transfer of high-quality serum and blood samples in clinical test. [principle of use] generally, the specific gravity of serum is about 1.030, the specific gravity of blood clot is about 1.092, and the specific gravity of separation gel of our company is between 1.045 and 1.065. The separation glue has good thixotropic and isolation properties. When the separation glue and the coagulated blood are centrifuged in the same tube, under the effect of centrifugal force, the hydrogen bond between the separation glue molecules is broken and converted into a low viscosity fluid. Because its specific gravity is between the blood cell and serum, the separation glue gradually accumulates between the serum and the blood clot in the centrifugation process. When the external centrifugation disappeared, the hydrogen bond between the molecules recombined to form a network structure, and the separation gel became a high viscosity gel again, forming a dense isolation layer to separate the serum and the blood clot. [Validity] 24 months

Serum separation gel, a kind of raw material commonly used in hospital laboratory, is inseparable from many biochemical analyses. It is an inert polymer, insoluble in water, and has high temperature resistance, low temperature resistance, oxidation resistance, and high stability. Some manufacturers such as Desheng's separation glue also have the characteristics of anti-radiation. With the improvement of peopleâ??s health awareness, blood testing has become more common. Serum separation gel is favored by various medical institutions. There are many manufacturers of separation gel. Due to the different requirements of medical institutions for separation gel, each manufacturer produces The components of the separation rubber are different, regardless of the transparency, color, viscosity, specific gravity and other aspects of the performance. The high-quality serum separation gel can shorten the serum separation time, and the separation gel is between the serum and blood cells, which can effectively protect the serum components, so as to realize the original tube on the machine and the original tube to save the serum for future reference, reducing the possibility of errors caused by re-transfer Sex. However, the impact of inferior separation gel on the test items cannot be ignored. The use of inferior separation gel detection can increase the triglyceride (TG) in the test results abnormally. Therefore, a comparison test must be done before using serum separation gel. The following is a quick, easy and easy-to-operate method to detect triglycerides in the separation gums of various manufacturers, as follows: 1. Apparatus and reagents: automatic biochemical analyzer, triglyceride (TRIG) reagent and calibration solution are special reagents for the instrument, 5ml disposable sterile syringe, Desheng serum separation gel blood collection tube, a certain brand of inferior serum Separation gel blood collection tube, traditional ordinary blood collection tube, 0.9% sodium chloride injection. 2. Method: The traditional ordinary blood collection tube is the control group A, the Desheng serum separation gel collection tube is the control group B, and a certain brand of inferior serum separation gel collection tube is the experimental group C. Each group randomly selects 10 blood collection tubes, each tube Add 5ml 0.9% sodium chloride injection separately, place in 37â?? water bath for 15min, centrifuge at 3000r/min for 10 minutes, measure the above tubes on the automatic biochemical analyzer, record the test results, and compare the results It can be found that TG cannot be detected in the blood collection tubes of group A and B, but different concentrations of TG can be detected in each tube of group C. This method can be used to conduct a comparison test to quickly and accurately identify the quality of the separation gel in the blood collection tube The pros and cons.
