Abstract

The invention discloses a solid dissolution rate testing device for a physics laboratory. Vertical side plates are arranged at the left side and the right side of the base respectively, transverse cylindrical shaft cylinders are arranged at the upper portions of the inner walls of the side plates respectively, and cylindrical rotary shafts are arranged in the shaft cylinders respectively and connected with the centers of the left side end face and the right side end face of a cylindrical testing cylinder respectively; two geared rings uniformly sleeve the outer parts of the left side and the right side of the testing cylinder and are meshed with inner gears respectively, the inner gears are both connected with an outer gear through a gear shaft, the outer gear is meshed with a rack, the lower portion of the rack is arranged in a casing pipe, and an outer calibrated scale is arranged on the side wall of the rack; a row of at least three inclined insertion cylinders are arranged at the portion, at the same height, on the inner wall of the testing cylinder, and inner calibrated scales extending downwards are arranged on the side walls of the insertion cylinders respectively; the lowerportion of the testing cylinder is provided with testing liquid. The solid dissolution rate testing device is convenient to use, the testing result is high in accuracy, and the operational safety ishigh.

Description

technical field [0001] The invention relates to the technical field of chemical experiment equipment, in particular to a solid dissolution rate testing device for a physics laboratory. Background technique [0002] At present, with the improvement of chemical experiment technology, the requirements for chemical experimental equipment are also getting higher and higher. [0003] Existing physical laboratory solid dissolution rate testing devices mostly adopt the structure of common vessels and solid supports, which often have the problems of inconvenient use and poor accuracy of test results. Contents of the invention [0004] The object of the present invention is to provide a solid dissolution rate testing device for a physical laboratory to solve the problems of inconvenient use and poor test result accuracy existing in the prior art. [0005] In order to achieve the above object, the method of the present invention provides a solid dissolution rate testing device for a...
