Purpose of test tube rack
Apr 13, 2022
The test tube rack is used to place the test tube, because the bottom of the test tube is protruding, so there is no place to put it without doing experiments.
The test tube is one of the reaction containers, which can be heated for the reaction between solid and liquid.
The test tube clamp can clamp the test tube, and can clamp the test tube when heating, so as to avoid hand contact with the test tube with too high temperature. The structure of ordinary optical microscope can be divided into two parts: one is mechanical device and the other is optical system.
Precautions for test tube rack
Put the test tube rack on the spacious and flat desktop. First put the alcohol lamp on the test tube rack, and then fix the test tube according to the height of the alcohol lamp (if it has been installed, you can install things in the test tube first). The mouth of the fixed test tube should face upward and the tail should be in the outer flame of the alcohol lamp. Then light the alcohol lamp for heating, and heat it evenly first and then locally. The main purpose of the test tube rack is to hold the test tube and hold it on the top of the test tube clamp handle. Do not press and hold the clamp to prevent the test tube from sliding.
