What is the serum separation gel

Serum separation gel is a viscous fluid that can separate serum and blood clots. It is physiologically inert and insoluble in water. The structure contains a large number of hydrogen bonds. The network structure composed of hydrogen bonds has excellent thixotropy and isolation properties. Under the action of centrifugal force, the network structure will be destroyed, but the good thixotropic properties can make the fluid gather again to form the network structure in a short time, thus playing the role of isolation.

It is commonly used in vacuum blood collection tubes to isolate serum and blood clots. It is very common in hospitals to "draw a blood". Many times the tubes contain different blood collection tube additives, and the golden head cap contains serum separation gel. tube.

The characteristics and functions of serum separation gel

The current serum separation gel has been produced with many different components, but the principles are the same, the specific gravity is controlled between 1.045-1.065g/cm3, so that the serum and blood clots can be isolated completely, such as Desheng serum separation gel The conventional control is 1.055g/cm3.

Now the appearance is more diversified, transparent, translucent, opaque, etc., without impurities, there is also a requirement for viscosity, 100,000 to 300,000 cps, such a viscosity is more conducive to thixotropy and isolation. Of course, the ambient temperature often affects the viscosity. When the winter is relatively cold, the viscosity is too high and it will be difficult to add glue; if the viscosity is too low in the summer, the flow will increase and it is not suitable to be placed. Therefore, the usual practice is to use a lower viscosity in winter, and use a higher viscosity serum separation gel in summer.

Serum separation gel is dedicated to disposable vacuum blood collection tubes, as a necessary material for the preservation, delivery and transfer of high-quality serum and blood specimens in clinical tests. There are also many custom-made serum separation gels for the extraction of platelets and other cells for use in cosmetic surgery and other body operations.

Defects of serum separation gel

Although the serum separation gel has many advantages, the serum separation gel itself is also caused by defects, such as easy to produce bubbles and affect the appearance, and the hydrolysis performance of serum separation gels of different components is also different.

Intolerant to radiation

Since it is used in blood collection tubes, the original characteristics of human blood must not be destroyed. It is better to preserve the tube without other bacteria, so as to further ensure the accuracy of the detection, while the earlier serum separation gel is not. If the conditions are suitable for irradiation, undesirable phenomena such as curing will occur after irradiation. Now this type of serum separator is still used in China. Driven by low cost, the test results are worrying.

Not resistant to hydrolysis

Polyolefins, polyesters and propylenes are more commonly used now, but their hydrolysis resistance is not good. They are hydrophilic. Long-term contact with water will cause changes in the pH value, leading to changes in the original properties of the blood. Test results Will also be affected to a certain extent.

Advantages of Desheng Serum Separating Gel

Desheng used more than two years to develop a new generation of resin serum separation gel. Although it is expensive, it solves the series of problems such as radiation intolerance and hydrolysis resistance, and it is used in special applications such as PRP, CPT, PST, etc. The tube has unique advantages in terms of extracting platelets and blood cells, and has obvious advantages in different fields.
