Preparation process of serum separation gel

 

The serum separation gel has four colors: transparent, translucent, opaque, and milky white. It smells light and has no impurities. It is a colloidal substance that cannot be dissolved in water. It has good thixotropy and isolation.

 

It is generally used for blood detection in hospitals. It can quickly separate the serum and blood cells in the blood, extract the serum, and test the corresponding items, so as to improve the efficiency of blood detection. Let's take you to understand its working principle and production process preparation method.

 

The working principle of serum gel separator is: the specific gravity of serum is about 1.02, the specific gravity of blood clot is about 1.08, and the specific gravity of gel separator is about 1.05. Through centrifugation, because of the thixotropy of gel separator, the gel changes into a liquid that can flow upward, and forms a separation layer between serum and blood clot, effectively separating serum and blood clot, and preventing the exchange between the two substances.

 

How to prepare:

1. First, a microbial reactor is used to make a transparent polymer resin

2. Add the prepared transparent resin adhesive to the vacuum mixer, add 0.5-1.0 silica by weight, 0.1-0.3 silane coupling agent and 2.0-3.5 plasticizer. The temperature is between 30 ℃ and 40 ℃. Stir for 0.5-1 hour under normal pressure and 0.5-1.5 hours under negative pressure.

3. Add a certain proportion of mixed white carbon black, thixotropic agent and defoamer into the mixer, or mix for 0.5-1 hour under normal pressure at 30-40 ℃, and then stir for 2-4 hours under negative pressure.

 

According to the above preparation method, and by controlling the reaction temperature and reaction time of the microchannel, a low specific gravity serum separation gel with a specific gravity of 1.030-1.040g/cm2 can be obtained.

 

The raw materials are generally styrene, pentene or butyl ester, butyl acrylate, dimethyl azodiisobutyrate and solvent. The mixing ratio and dosage are not described too much here.
