Product introduction

Plastic test tube caps are plastic products used to seal test tubes, usually made of plastic materials such as polypropylene (PP) and polyethylene (PE). They are mostly cylindrical or conical in shape, and the size is adapted to the test tube. They seal the test tube mouth by tightening or twisting. They can prevent the leakage and volatilization of the test tube and the entry of foreign impurities, ensuring the purity of the experimental samples and the accuracy of the experimental results. At the same time, they also have a certain degree of elasticity, which is easy to install and disassemble.

Product features

(1) Excellent material: good chemical stability, corrosion resistance, and not easy to react with the substances in the test tube.

(2) Good sealing: fits tightly with the test tube to prevent liquid volatilization, leakage and external contamination.

(3) Convenient operation: has a design that is easy to open and close, such as a flange or anti-slip pattern.

(4) Various colors: transparent ones are easy to observe, and colored ones can be used to distinguish the contents of different test tubes.

(5) Economical and practical: low cost, can be used in large quantities, and can be reused.

Product applications

(1) Chemical experiments: prevent reagent volatilization, avoid cross-contamination of different reagents, and ensure the accuracy of the experiment.

(2) Biological testing: protect biological samples, maintain their activity and stability, and facilitate sample storage and transportation.

(3) Medical testing: seal test tubes containing blood, urine and other samples to prevent sample leakage and contamination, and ensure reliable test results.
