A comprehensive kit for biochemical experiments

Abstract

The invention discloses a comprehensive kit for biochemistry experiments, and relates to the technical field of experimental instruments. The comprehensive kit comprises a kit body, a cover body, an operation board and a reagent shelf, wherein the reagent shelf is used for placing a reagent tube and a color developing agent tube; a supporting ring is fixed in the kit body; the supporting ring is provided with a concave channel; the peripheral surface of the box body is provided with an opening; and the bottom surface of the kit body are provided with four penetrating holes. By the rotation ofa rotating column and the coordinated use of the concave channel and convex sliding blocks, the operation board is driven to rotate along the supporting ring; one type of test paper and a colourimetric card thereof are at the position of a sector-shaped operation hole, and by the dropwise addition of experiment reagents, the test paper is developed and is compared with the colourimetric card to test parameter values; by the rotation of the rotating column, another type of test paper and a colourimetric card thereof are under the sector-shaped operation hole, another parameters can be tested; and therefore, the problem that laboratory appliances are too many to be place disorderly, so that the experiment is not facilitated for users is solved.

Description

technical field [0001] The invention belongs to the technical field of experimental instruments, in particular to a comprehensive kit for biochemical experiments. Background technique [0002] Add the test reagent dropwise to the test paper or the color developer, and produce a color through the chemical reaction between the test reagent and the test paper or the color developer, and then compare the color produced by the test paper or the color developer with the color of the color card It is a common experimental method in student chemistry and biology experiments to determine the properties of the experimental reagents based on the parameter values ​​corresponding to the colors of the color comparison card, such as digestive enzyme experiments, pH value measurement experiments, etc. [0003] In the traditional reagent experiment, it is necessary to use color comparison cards, test papers, and color reagents, etc., and it needs to be compared. It is convenient to observe ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a comprehensive kit for biochemical experiments. By rotating the rotating column and using the concave groove and the convex slider to drive the operation plate to rotate along the support ring, one type of test paper and The color comparison card is at the fan-shaped operation hole, and the parameter value is determined by comparing the color development of the test paper with the color comparison card by dropping the experimental reagent, and making another type of test paper and its color comparison card in the fan-shaped operation hole by rotating the rotating column. Below, another parameter can be measured, which solves the problem of messy and inconvenient experiments caused by too many experimental equipment
