Silica gel(Silica gel; Silica)Alias: Silicic acid gel is a highly active adsorption material, which is an amorphous substance. Its chemical formula is mSiO2·nH2O; it does not react with any substance except strong alkali and hydrofluoric acid.
It is insoluble in water and any solvent, non-toxic, tasteless, and chemically stable.
Neutral sponge silicon plastic test tube and Erlenmeyer flask stopper are widely used in the cultivation of bacteria in medical and biological research. This new type of test tube stopper has good air permeability, flexibility, high temperature resistance and high pressure. The use time is generally up to 3 years. More convincing, it is an ideal and advanced new type bottle stopper, which is better than the cotton yarn bottle stopper in the past. It has been applied by users such as national universities, hospitals of traditional Chinese medicine, biological research institutes, health and epidemic prevention stations, etc., and the response has been good.
Features
1. It can be applied to different types of test tubes and Erlenmeyer flasks, and the operation is convenient and light.
2. Neutral, breathable, non-toxic, high temperature resistance 160-180℃, open flame disinfection does not catch fire, low temperature -70℃, high pressure 0.103MPa 15 minutes unchanged.
3. Cultivation of bacteria, Leptospira, Ureaplasma urealyticum, the growth rate and amount of growth are the same as those of the control.
4. Clean, dry and store after use. Generally, it can be used for 1000 times, and the cleaning method can use detergent.
