Description

Technical Field

[0001] The invention relates to the technical field of test tube cleaning devices, in particular to a biological test tube ultrasonic cleaning device and a cleaning method. Background Art

[0002] Test tubes are often used in biomedical experiments. They are often used as reaction containers for small amounts of reagents and are usually used at room temperature or when heated. At present, in order to reduce the workload of manual test tube cleaning, ultrasonic cleaning machines are used to clean the test tubes. However, there are still the following shortcomings in the use of ultrasonic cleaning machines to clean the test tubes: First, since no brush is used during the cleaning process, it is difficult to effectively clean off the solid impurities adhering to the inner wall of the test tube, resulting in the need for manual subsequent selective cleaning operations based on the test tube conditions; secondly, the placement, removal, and draining of the test tubes all require the operator to use tools to participate, resulting in the entire test tube cleaning operation being time-consuming and labor-intensive, and less convenient.

[0003] In view of this, it is particularly important to design and manufacture a test tube cleaning device with high cleaning efficiency, good cleaning effect and convenient cleaning operation during use in biomedical experiments. Summary of the invention

[0023] Beneficial effects

[0024] The present invention provides a biological test tube ultrasonic cleaning device and a cleaning method. Compared with the prior art, it has the following beneficial effects:
