Problems solved by technology

At this stage, test tube stoppers such as wooden stoppers or rubber stoppers are used to seal test tubes. Although these test tube stoppers can play a certain role in airtightness, they have been rejected by experimenters due to their large volume and mass, and the shortcomings of being easily contaminated and damaged. criticize
In addition, such test tube stoppers are not easy to pull out after being stored on the test tube for a certain period of time or after the heated test tube is cooled, which brings inconvenience to the experiment.

Abstract

The invention discloses a novel test tube sealer, which comprises a cover body. An annular crack is formed in the lateral wall of the cover body. The lateral wall of the cover body is divided into anouter wall and an inner wall by the annular crack. A waterproof plastic cover is adhered on the inner side of the outer wall. The external side of the outer wall is provided with an annular groove. Alocking hoop is installed in the annular groove. Compared with wooden plugs and rubber plugs, the provided sealer can well seal a test tube and is capable of preventing the volatilization of reagentsduring the experiment process such as water bath, burning, and the like. When a test tube is used as a container to store substances, the sealer is used to seal the test tube, and the test tube can bestored more conveniently. Furthermore, the sealer has the advantages of simple structure, good sealing performance, and low cost, and is disposable. Thus the tedious and repeated washing of test tubeplugs and the risk that a reagent is polluted are avoided effectively.

Description

technical field [0001] The invention relates to a novel test tube sealer, which belongs to the technical field of measuring tools. Background technique [0002] The test tube sealer is a condition and tool specially used to seal the test tube mouth and provide a seal when the substance that needs a sealed environment is stored in the test tube. In various laboratory places such as inorganic chemistry, organic chemistry, and biochemistry, test tubes are one of the most frequently used experimental equipment. In the process of doing various experiments, it is often necessary to burn, bath or preserve the test substance together with the test tube. At this stage, test tube stoppers such as wooden stoppers or rubber stoppers are used to seal test tubes. Although these test tube stoppers can play a certain role in airtightness, they have been rejected by experimenters due to their large volume and mass, and the shortcomings of being easily contaminated and damaged. criticized. ...
