Middle school miniature chemical experiment instrument

Abstract

The invention discloses a middle school miniature chemical experiment instrument, which comprises a support seat, wherein an inner cavity of the support seat is fixedly connected with a storage battery; the bottom of the support seat is fixedly connected with a suction disc; the left end of the outer surface of the support seat is fixedly connected with a controller; the outer surface of the controller is sequentially and fixedly connected with a temperature control press key and a sensor switch from the left side to the right side; the middle end of the top of the support seat is fixedly connected with a first support rod. A heating plate is fixedly connected with the lower end of the inner cavity of the heating seat, so that chemical instruments such as a beaker can be heated; through the effect of the temperature sensor, people can conveniently detect the temperature inside the chemical instruments such as the beaker; the detection result can be displayed through the display; the problems that the existing chemical experiment instrument is lack of the substance heating capability, so that a teacher needs to additionally carry tools such as a alcohol burner during the experiment, and the teaching burden of the teacher is increased are solved.

Description

technical field [0001] The invention relates to the technical field of experimental instruments, in particular to a micro chemical experimental instrument for middle schools. Background technique [0002] Chemistry is a kind of natural science. It studies the composition, properties, structure and change law of matter at the molecular and atomic levels. It is the science of creating new matter. The world is composed of matter, and chemistry is used by human beings to understand and transform the material world. One of the main methods and means. It is a subject with a long history and full of vitality. Its achievements are an important symbol of social civilization. There are two forms of change in chemistry, chemical change and physical change. When the teacher is doing chemical experiments , needs to use chemical experiment equipment, but the existing chemical experiment equipment lacks the ability to heat substances, so that the teacher needs to carry additional tools suc...
