Features of new type silicone rubber stopper are given as below:
1. Applicable to each different aperture test tube and triangle flask, having wide size range, saving time and labor with convenience and practicality.
2. Neutral 250 high-temperature resistance and high-pressure resistance (it will not burst and stopper), good air permeability, it can be frozen under low temperature of 60 with flexible performance.
3. It has no inhibition to growth of any bacterium, biological cell and virus, and is the same as cotton stopper (means growth conditions).
4. Without water sucking and pollution, it is more convenient for sampling of cotton skewer.
5. No burning during sterilization with open fire, convenient cleaning, without smell and deformation during dry bake of 200. (It should be cleaned and dried after using).
