turer can effectively improve its quality by accurately controlling the key indicators such as specific gravity, thixotropy and viscosity, which can not only save more time and cost for the blood collection manufacturer, but also win its own reputation and image. Desheng, as a professional manufacturer of anti-irradiation separation adhesive, all indicators are formulated by the R&D personnel according to the experimental requirements, with stable performance and increasing customers. If As a common additive in vacuum test tubes, the quality control of anti-irradiation separation gel is very strict, and there are also clear requirements for various values, such as pH value, physiological inertia, thixotropy, specific gravity, etc., which are important indicators to measure the quality of serum separation gel. Inspectors must also formulate corresponding quality standards and test methods according to these important parameters. In the actual application scenario, these indicators will also directly affect the use effect of reagents, so we will focus on introducing the key to the quality control of serum separation gel.

1、 Control the specific gravity of anti-irradiation separation gel

As a widely used additive, it mainly depends on its precise specific gravity. By controlling the specific gravity, different cellular substances in the blood are separated, and then extracted or tested. Generally, the specific gravity deviation will not exceed 0.002g/cm3. If the specific gravity is not well controlled and cannot be overturned in the test tube, the whole test will not be carried out. The precise specific gravity is also the reflection of the overall quality of the anti-irradiation separation gel.

2、 Control the thixotropy and viscosity of anti-irradiation separation adhesive

The reason why the anti-irradiation separation adhesive can rapidly form a network structure is that the thixotropic property plays a role. Once the thixotropic property is affected, it will also cause the situation that it cannot be overturned. Moreover, it is to control the viscosity of the anti-irradiation separation gel. The importance of viscosity is mainly reflected in the gelation and fluidity. If the gelation is difficult or the gel hangs on the wall, which will affect the test tube, it will also indirectly affect the customer's judgment on the quality of the separation gel.

3、 Control the storage time of anti-irradiation separation adhesive

The reason why the storage time of the anti-irradiation separation adhesive needs to be controlled is that it is the key to determine the quality. Due to the different raw materials and processes produced by different manufacturers, the storage time also varies. Some can only be stored for one year, and some can be stored for three years. If the storage time is long, and there is no aging phenomenon, and the performance does not change, then the quality of the anti-irradiation separation adhesive is controlled in place. Moreover, the storage time after full contact with blood is also the standard for quality inspection.

When producing the anti-irradiation separation gel, the manufacturer can effectively improve its quality by accurately controlling the key indicators such as specific gravity, thixotropy and viscosity, which can not only save more time and cost for the blood collection manufacturer, but also win its own reputation and image.
