Test tube storage rack capable of cleaning test tubes

Abstract

The invention discloses a test tube storage rack capable of cleaning test tubes and relates to a chemical experimental instrument. A supporting rod is arranged at a central position of a bottom plateand penetrates through a second laminate, a third laminate and the center of a ring magnet to reach a central position of the bottom of a top plate; a plurality of through holes are formed in the upper surface of the second laminate and correspond to grooves in the bottom plate; a plurality of perforations are formed in the upper surface of the third laminate and correspond to the through holes inthe upper surface of the second laminate; necked-down clamping rings are arranged in the perforations; the lower part of a test-tube brush penetrates through the necked-down clamping rings to be suspended at the lower ends of the perforations; the upper part of the test-tube brush is clamped on edge surfaces at the upper ends of the necked-down clamping rings. According to the test tube storage rack disclosed by the invention, to-be-cleaned test tubes can be arranged on the test tube storage rack in a centralized manner, and the test tubes are cleaned while rotating the test-tube brush. Therefore, the conditions that a person needs to hold the test tube by one hand and hold the test-tube brush by the other hand, so as to clean the test tubes one by one and the test tubes drop to be damaged due to difficulty in holding are avoided in the traditional test tube cleaning process.

Description

technical field [0001] The invention relates to a chemical experiment instrument, in particular to a test tube placing rack for cleaning test tubes. Background technique [0002] The test tube racks in the prior art generally only provide the storage of test tubes alone, and have no corresponding function for the cleaning of test tubes. Due to the needs of chemical experiments, test tubes are widely used. The traditional way of cleaning test tubes is mainly manual cleaning. During the process, it is necessary to hold the test tubes in one hand and the test tube brush in the other hand to clean them one by one. The cleaning work is time-consuming and labor-intensive, and the test tubes are easy to drop if you do not pay attention while holding the test tubes in your hand, causing damage and causing inconvenience to the cleaning personnel. Existing batch test tube cleaning machines are often expensive and costly to use. Contents of the invention [0003] In order to overc...

Problems solved by technology

[0003] In order to overcome the deficiencies in the background technology, the present invention discloses a test tube placement rack for cleaning test tubes. Through the present invention, the test tubes to be cleaned can be concentratedly placed on the test tube placement rack, and the test tubes are cleaned while rotating the test tube brush. The process saves time and effort, avoiding the need to hold the test tube in one hand and the test tube brush in the other hand to clean one by one in the traditional process of cleaning test tubes. The cleaning work is time-consuming and labor-intensive, and it is easy to drop the test tube and damage it
