Reciprocating test tube holder for chemical testing experiment

Abstract

A test tube support for reciprocating chemical detection experiments, including a mounting seat, a lifting device is fixed on the right side of the mounting seat, a sleeve is provided on the left side of the mounting seat, a guide column is provided in the sleeve, and the lifting device The top end and the top of the guide column are fixedly connected with a mounting plate, and a number of test tube through holes are provided on the mounting plate, rubber sleeves are provided on the side walls of the test tube through holes, and a number of test tube protection devices are fixed on the mounting base; A reciprocating device is arranged under the seat, and the reciprocating device includes a base plate, and support plates are fixedly connected to both sides of the base plate. The beneficial effect of the present invention is that the lifting device is used to drive the lifting of the mounting plate, so as to drive the lifting of the test tube, which is more convenient and effective than the traditional method of using a backing plate to solve the problem of the height of the instrument and the test tube; the test tube protection device can effectively protect the height of the test tube The bottom, so that it is not damaged; the vibration device can vibrate the test tube, which is beneficial to the experiment.

Description

technical field [0001] The invention relates to the technical field of chemical detection experiments, in particular to a test tube support for reciprocating chemical detection experiments. Background technique [0002] Chemistry is a kind of natural science, which studies the composition, properties, structure and changes of substances at the molecular and atomic levels; it is the science of creating new substances. The world is composed of matter, and chemistry is one of the main methods and means used by human beings to understand and transform the material world. It is a subject with a long history and full of vitality, and its achievements are an important symbol of social civilization. There are two forms of chemical change and physical change in chemistry. [0003] Chemical testing refers to the use of chemical analysis instruments, physical and chemical instruments and other equipment to test the finished products of chemical products such as reagent solvents, daily...

Problems solved by technology

[0004] In the process of chemical experiments, test tubes are often used. Since the test tubes are easily damaged, they need to be very careful when using them; in some experiments, it is also necessary to shake the test tubes, and the experimenter needs to shake them by himself. Test tubes, when there are many test tubes, the workload is greater
