Magnetic stirring device for teaching

Abstract

The invention provides a magnetic stirring device for teaching. The magnetic stirring device comprises an upper annular plate, a lower annular plate, a magneton and a rope tape, wherein the upper annular plate and the lower annular plate are fixed by a plurality of supporting columns which are uniformly distributed around the axes of the upper annular plate and the lower annular plate; a cross supporting plate is arranged inside the upper annular plate; the end part of the cross supporting plate is fixedly connected with the upper annular plate; a center plate is arranged at the center of thecross supporting plate; the magneton is positioned between the upper annular plate and the lower annular plate; a suspender is arranged at the center part of the magneton; the upper end of the suspender is fixed on the center plate and the lower end of the suspender is rotationally connected with the magneton; an inverted U-shaped rod is arranged on the center plate and the end part of the inverted U-shaped rod is fixed on the upper surface of the center plate; a rotating sleeve sleeves the inverted U-shaped rod; a circular groove is formed in the outer wall of the rotating sleeve; the rope tape can surround the inner part of the circular groove. The magnetic stirring device for teaching, disclosed by the invention, has the beneficial effects that direct contact between the magneton and areactor is avoided, and the friction of the magneton to the inner wall of the reactor is avoided while a stirring effect is ensured.

Description

technical field [0001] The invention relates to a magnetic stirring device for teaching. Background technique [0002] When conducting microbial experiments, it is often necessary to use a round bottom flask to stir the internal mixture with magnets. In order to mix the materials evenly, the magnets need to be rotated at high speed. Since the magnets are in direct contact with the inner wall of the round bottom flask, during the rotation process Neutrons wear the inner wall of the flask, and long-term use will cause damage to the flask. If the damage occurs during the reaction, it will easily lead to the failure of the reaction. Contents of the invention [0003] The problem to be solved by the present invention is to provide a magnetic stirring device for teaching, which overcomes the deficiencies in the prior art. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a magnetic stirring device for ...
