Leak test tube

Abstract

The invention relates to a leak test tube, which is U-shaped and consists of a test tube body and a handle, wherein the test tube body is provided with a plurality of leaks; and when an experiment that gas is generated from solid and liquid is performed, a solid reagent is put into the test tube body, the test tube body is put into the traditional test tube, and then a liquid reagent is added. People can control the reaction velocity by increasing or reducing the contact area between the solid reagent and the liquid reagent.

Description

Technical field [0001] The invention relates to the field of chemical experiment equipment. Background technique [0002] At present, the test tubes widely used are mostly made of glass, and various chemical experiments can be done with this test tube. But this test tube is not easy to control the reaction rate when doing solid-liquid gas generation experiments. Contents of the invention [0003] In order to overcome the disadvantage that the existing test tube is not easy to control the reaction rate in the experiment of solid-liquid gas formation, the present invention provides a leaky test tube, which can effectively control the reaction rate when used in conjunction with the traditional test tube. [0004] The technical solution adopted by the present invention to solve its technical problems is: the present invention is U-shaped in shape and consists of a test tube body and a handle. In the body, put the test tube body into the traditional test tube, and then add th...
