Product features

Test tube without rim plain is made of high-quality borosilicate glass, which has extremely high transparency, allow you to clearly observe the state, color changes and reaction process of the substances in the test tube. Can provide good visual effects. It has good tolerance to most chemicals and   will not easily react with common acids, alkalis, salts and other solutions, ensure the accuracy of experimental results.

Test tubes without rim plain can withstand a certain degree of high temperature and are not easily deformed or broken during heating operations. They are suitable for experiments that require heating, such as heating for dissolution, evaporation and concentration, etc. Test tube without rim plain has a flat port, which facilitates various operations, makes the test tube more stable when placed and less likely to tip over. Test tubes without rim plain are available in different length, diameters and capacity specifications to meet the needs of different experiments. Some Test tube without rim plain have graduation marks to facilitate you to accurately measure and control the volume of the substance in the test tube. This is very helpful for experiments that require precise metering.

Test tube without rim plain has a smooth body, round tube bottom, and round tube mouth with thickened rim and wall thickness to reduce the probability of damage caused by slight accidental collisions. Low expansion rate, high temperature resistance, acid and alkali resistance, high strength, high hardness, high light transmittance, high chemical stability, smooth surface, no burrs, no protrusions, fine craftsmanship, delicate and strong, beautiful and textured.

Product applications

Chemistry experiments: In chemistry laboratories, glass test tubes are one of the most commonly used experimental equipment. It can be used for chemical reactions, solution preparation, material heating and other operations. For example, in acid-base neutralization reaction experiments, test tubes can be used to observe color changes and precipitation formation during the reaction.

Biological experiments: In biological experiments, glass test tubes are also widely used. It can be used for microbial culture, cell culture, blood sample collection, etc. For example, in a microbial culture experiment, the culture medium can be put into a test tube to culture bacteria or fungi.

Teaching experiments: Because test tubes are simple to operate, they are also widely used in teaching experiments. It can help students better understand the experimental principles and operating methods of subjects such as chemistry and biology.
