Product introduction
Test tube cork stopper is a stopper used to seal the opening of a test tube, usually made of natural cork or other similar material.
Product features
(1) Diverse materials: natural cork, which is soft, elastic, breathable, and chemically stable; there are also synthetic materials such as rubber and plastic, which are low-priced, rubber has good elasticity and flexibility, and plastic has high strength and is not easy to deform.
(2) Good sealing: It can fit tightly to the mouth of the test tube to prevent leakage of substances and entry of external impurities.
(3) Diverse functions: It can fix instruments such as glass tubes and thermometers, and can also assist in controlling reaction conditions.
