Description

Technical Field

[0001] The utility model relates to the field of experimental equipment, in particular to a test tube support for laboratories which is easy to dry. Background Art

[0002] Experimental equipment refers to the instruments and tools needed for experiments. Experimental equipment mainly refers to the instruments and tools designed for students to use for experiments in class. It includes physics experiment boxes, chemistry experiment boxes, and biology experiment boxes for junior and senior high schools, as well as microscopes, magnifying glasses, voltmeters, ammeters, and test tubes. Test tubes are commonly used experimental instruments in laboratories. They are used as reaction containers for small amounts of reagents and are used at room temperature or when heated. Test tubes are divided into ordinary test tubes, supported test tubes, centrifugal test tubes, etc. At present, students need to use test tubes when conducting experiments or research in the laboratory. After the test tubes are used, the test reagents used this time will remain, and the reagents will adhere to the inner wall of the test tubes. The test tubes need to be cleaned. In order to ensure dryness, the cleaned test tubes need to be dried.

[0003] According to Chinese patent number CN216522766U, a test tube drying and placing device for laboratory use is disclosed, which includes a box assembly, an electric control cabinet, a drying assembly, a button switch, a drain pipe, a cover and an exhaust pipe.
