The primary purpose of a rubber stopper is to prevent a gas or liquid from escaping its container during a scientific experiment. Rubber stoppers can also prevent the contamination of samples by protecting the contents of laboratory glassware from air. Last, the use of rubber stoppers allows experimenters to shake or mix solutions without spilling them.

Products Material

Silicone:The term silicone covers a large group of materials in which vinyl-methyl-silicone (VMQ) is often the central ingredient. Silicone elastomers as a group have relatively low tensile strength, poor tear and wear resistance. However, they have many useful properties as well. Silicone has a good heat resistance, good cold flexibility, and good ozone and weather resistance as well as good insulating and physiologically neutral properties.

 

Natural rubber is one of the most important polymers for human society. Natural rubber is an essential raw material used in the creation of more than 40,000 products. It is used in medical devices, surgical gloves, aircraft and car tires, pacifiers, clothes, toys, etc. Natural rubber is obtained from latex
A whitish milky fluid containing proteins, starch, alkaloids, etc., that is produced by many plants. In some plants it also contains rubber.
, a milky liquid present in either the latex vessels (ducts) or in the cells of rubber-producing plants. Around 20,000 species of plants produce latex, but only 2,500 species have been found to contain rubber in their latex. The biological function of rubber for the plants is not fully known. However, it has been shown that rubber can help plants to heal after they are damaged, by covering wounds and stopping the bleeding. This blocks the entry of harmful bacteria and viruses into the plants.
