The invention discloses a novel test tube rack for experimental teaching. The novel test tube rack for experimental teaching comprises a test tube rack and a plastic storage box; a second test tube fixing plate is arranged below the test tube rack; test tube rack outer supporting smooth rods are arranged at the two ends above the second test tube fixing plate correspondingly; test tube rack innersupporting smooth rods are arranged in the two test tube rack outer supporting smooth rods; a plastic storage box door is arranged on one side of the opening position of a box body of the plastic storage box; a fixed valve is provided, so that the lengths of parts, exposed out of the test tube rack outer supporting smooth rods, of the test tube rack inner supporting smooth rods can be adjusted, the adjustability of the distance between the two fixing plates is realized, and the requirements of the test tubes with different length during experiment or storage can be met; the plastic storage boxis arranged outside and a sealing strip is arranged at the opening position of the plastic storage box, so that the test tubes and the test tube rack can be stored safely and properly, dust and dirtcan be prevented, and the requirements on adjustability of the supporting rods of the test tube rack, dust prevention and safe storage during teaching can be met.
Description
technical field [0001] The invention belongs to the related technical field of experimental teaching equipment, and in particular relates to a novel test tube rack for experimental teaching. Background technique [0002] Test tube rack, a kind of chemical experimental instrument, the test tube rack is the most basic experimental instrument in the chemical laboratory used to place (sometimes the test tube can also be placed on the test tube rack to observe the phenomenon of a certain experiment) and dry the test tube , the test tube rack is equipped with a corresponding number of test tube fixing holes. If there are test tube fixing holes, the test tube can be placed vertically for use or to continue to observe the progress of the reaction. The test tube is one of the reaction containers, which can be heated and carried out between solid and liquid Because the bottom of the test tube is protruding, the test tube can be placed on the test tube rack when not doing experiments o...
