Serum separation gel is a viscous fluid with a large number of hydrogen bonds in its structure, forming a network structure due to the association of hydrogen bonds. Under the action of centrifugal force, the network structure is destroyed and becomes a fluid with low viscosity; After the centrifugal force disappears, it forms a network structure again and returns to a fluid with high viscosity. This property is called thixotropy. By utilizing this characteristic, a serum separation gel can be prepared. When the separation gel and coagulated blood are centrifuged in the same test tube, the separation gel forms a gel like isolation layer between the serum and the blood clot Chemicalbook, separating the serum and the blood clot. This improves the recovery rate of serum and preserves the serum in its original state, simplifying the clinical testing process and improving work efficiency. Serum separation gel can completely separate serum and thrombus in blood samples and accumulate in the center of the test tube to form a barrier, preventing component exchange between the two and ensuring the accuracy of the test results. Especially during the storage and transportation of blood samples, it is necessary to isolate and process them.

Desheng is an established blood test reagent company with 14 years of R&D and production experience.All kinds of blood collection additives we can supply. If you in need of serum separation gel ,please feel free to contact us.
Our company's separation gel is a patented product with unique composition. Please do not mix it with other suppliers' products, so as to avoid product damage and unnecessary loss to you;
The recommended temperature range of separation gel is -20 ~ +90ºC. The viscosity of this product will change greatly with the change of ambient temperature. Too low ambient temperature may cause difficulty in dispensing. It is suggested that when the ambient temperature is lower than 15 ºC, the water bath can be heated to 60-70ºC, the viscosity can be reduced, and the dispensing efficiency can be improved;When adding gel at room temperature, the phenomenon of "wire drawing" appears, which can increase the temperature of gel adding properly or break the wire by vibration;
Our separation gel is treated with high vacuum, there is almost no air in the gel. It is generally not recommended to stir in the process of transfer and gel addition, because it is easy to cause a large amount of air in the stirring process of the gel;
After adding the gel into the test tube, the plane flow distance of the gel is ≤ 5mm through the inverted test at 60ºC for more than 20 consecutive days under vacuum. It can ensure that the container will not flow more than 5mm for 20 consecutive days at 60 ºC and will not affect the normal use of blood tube. Even so, we still suggest that during the long-term transportation, the blood tube containing the separation gel should not be inverted;
It is recommended not to touch the separation gel directly by hand. When sticking to the skin, it can be scraped off with a clean iron blade, wiped off most of the gel with a waste newspaper, cleaned with DMC, D4 and other organic solvents, or cleaned with detergent powder mixed with sawdust and detergent, and then washed with water.
