Product features

Test tube without rim plain is made of neutral glass and has high transparency, allow you to clearly observe the state, color changes and reaction processes of the substances in the test tube, and provide good visual effects. Test tube without rim plain has a certain degree of stability to most common chemicals and will not easily cause chemical reactions to affect the experimental results. But for some highly corrosive chemicals, special protective measures may be required.

Test tube without rim plain can withstand certain high temperatures. During heating operations, neutral glass test tubes can remain stable within an appropriate temperature range and will not easily deform or break. But be careful to avoid rapid temperature changes, which may cause the test tube to rupture. 

Test tube without rim plain has a flat port, which facilitates various operations and makes the operation more precise and convenient. At the same time, the flat mouth design also makes the test tube more stable when placed and less likely to tip over. Different lengths, diameters and capacity specifications are available to meet the needs of different experiments. Some test tubes without rim plain have graduation marks to facilitate you to accurately measure and control the volume of the substance in the test tube.

Product applications

Test tube without rim plain is widely used in laboratories, medical treatment, industry, education and other fields due to their transparency and corrosion resistance.

Chemical experiments: In chemical laboratories, neutral glass test tubes are one of the most commonly used experimental instruments. They 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 process.

Biological experiments: In biological experiments, neutral glass test tubes are also widely used. They can be used for microbial culture, cell culture, blood sample collection, etc. For example, in microbial culture experiments, culture media can be placed in test tubes for bacterial or fungal culture.

Teaching experiments: Because neutral glass test tubes are relatively low in price and simple to operate, they are also widely used in teaching experiments. They can help students better understand the experimental principles and operation methods of subjects such as chemistry and biology.
