Description

Technical Field

[0001] The utility model relates to the field of test tubes, in particular to a cleaning device for laboratory test tubes. Background Art

[0002] Test tubes are commonly used instruments in chemical laboratories. In laboratories, test tubes are widely used. They can be directly heated and used as reaction containers for small amounts of reagents. Test tubes are divided into ordinary test tubes, supported test tubes, centrifugal test tubes, etc. In the process of fertilizer research and development, test tubes are often needed to prepare various fertilizer formulas. After use, the test tubes need to be cleaned so that they can be reused.

[0003] Test tubes are generally cleaned manually using a cleaning brush. However, in order to clean them thoroughly, the test tubes need to be rinsed with water and then cleaned manually. Since the test tubes are deep and the outer walls of the test tubes are slippery, manual cleaning of the test tubes is not only time-consuming and laborious, but also easily causes the test tubes to slip and break. Therefore, a laboratory test tube cleaning device is proposed to solve the above problems. Utility Model Content
