Abstract

The invention discloses a test-tube stand for chemical experiments. The test-tube stand comprises a support shell and is characterized in that a protective cover is fixedly connected to the top of thesupport shell, an upper fixing plate is fixedly to the top of the protective cover, through holes are evenly formed in the fixing plate, the top of the support shell is provided with grooves, the inner bottom of each groove is provided with an arc-shaped heat-conduction plate, a heating plate is fixedly connected to the bottoms of the arc-shaped heat-conduction plates through heat-conduction wires, a resistance heating wire winds the outer side of the heating plate, a circuit board is fixedly mounted at the inner bottom of the support shell, a power switch is mounted on the outer side of thesupport shell and electrically connected with the circuit board, the circuit board is electrically connected with the resistance heating wire, one side of the protective cover is provided with an openslot, and a placing tank is arranged inside the open slot. The test-tube stand has the advantages that the test-tube stand is reasonable in design, test tube heating can be performed conveniently, test tube drying can be facilitated, residual water, which affects experiment data, in test tubes can be prevented, and the test-tube stand is worthy of energetic popularization.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a test tube rack for chemical experiments. Background technique [0002] After the chemical experiment test tube is cleaned, the water droplets or water vapor remaining in the tube cannot be removed in time. The water droplets stay along the tube wall and often accumulate in the bottom of the test tube. When the test tube is used for testing, the accumulated water at the nozzle will affect the experiment. Moreover, long-term water accumulation will cause water stains on the surface of the lower plate of the test tube rack, and even be oxidized and corroded. , Therefore, it is necessary to invent a kind of test tube rack for chemical experiments to solve the above problems. Contents of the invention [0003] The object of the present invention is to provide a test tube rack for chemical experiments to solve the problems raised in the above background technology. [...
