Specific Gravity Of Serum Separating Gel 1.045-1.065g/Cm3

Serum separating gel is a viscous fluid, which can separate serum and blood clots. It is physiologically inert, insoluble in water, and contains a large number of hydrogen bonds in its structure. It forms a network structure with excellent thixotropic and isolation properties. Under the action of centrifugal force, the reticular structure will be destroyed. If the thixotropic property is strong, the fluid can gather in a short time to form a reticular structure, so as to achieve the purpose of isolation.

Serum separating gel

The serum separating gel is mostly used in vacuum blood collection vessels to isolate blood clots and serum. The yellow tube for blood drawing in the hospital will contain serum separating gel. If you want to ensure the accuracy of serum separating gel, you need to rely on its performance and specific gravity.

Today, although many different manufacturers are producing serum separating gel, the specific gravity control is difficult to be stable. The conventional specific gravity should be controlled between 1.045-1.065g/cm3, just as the specific gravity of serum separating gel produced by Desheng is controlled at 1.055g/cm3.

Generally, the blood will be divided into three layers after centrifugation in the gel separating accelerator tube. The top layer is light yellow liquid serum, with a specific gravity of 1.02-1.03. The lowest layer is blood clot, with a specific gravity of 1.08-1.09. It can be seen from the comparison that the specific gravity of the blood clot is much higher than that of the serum, and the specific gravity of the serum separating gel is between 1.050-1.060, just between the two. The blood clot is divided into upper and lower layers by centrifugation.

The quality of the serum separating gel determines the separating effect. If the quality of the separating gel of the blood collection tube is poor and the specific weight cannot meet the requirements, the separating effect of the serum will be affected, and the separating gel and the serum will easily converge.

In addition to the specific gravity of serum separating gel, there are also requirements for viscosity. The viscosity of separating gel within this range is conducive to thixotropy and isolation when the viscosity is between 100000-300000kPa. It should be noted that the viscosity is affected by the ambient temperature. Cold winter and high viscosity will lead to difficulty in adding glue, while hot summer and low viscosity will lead to increased mobility, which should not be kept for a long time. It is generally required to use serum separating gel with lower viscosity in winter and higher viscosity in summer.

As an important material for the preservation, transmission and transfer of high-quality serum and blood samples in clinical tests, the serum separating gel must be produced by manufacturers with reliable quality.
