Cuvette Transmittance Tester

Abstract

The invention discloses a cuvette light transmittance tester, which comprises a base, a reaction disc installed on the base, a reaction tank, a driving device, a light emitting device, a photoelectric receiver and a shell cover; the reaction disc passes through the driving device and the base Rotational connection, the edge of the reaction plate is connected with a plurality of cuvettes forming a circle along the circumferential direction; the reaction tank is provided with an annular groove with an upward opening along the circumference, and the multiple cuvettes are located in the ring. In the groove; the light-emitting device is located in the reaction tank, and the emitted light beam is received by the photoelectric receiver after being connected with the cuvette, and the photoelectric receiver is electrically connected with the data analyzer of the tester through a wire; the edge of the shell cover and the The edge is connected, and the cuvette joint is located at the opening on the top surface of the shell cover. After adopting the above structure, the differences among cups, between lines and between batches are reduced, so that the results of biochemical analysis through cuvettes are more accurate.

Description

technical field [0001] The invention relates to the technical field of biochemical analysis equipment, in particular to a cuvette transmittance tester. Background technique [0002] A cuvette, also known as a cuvette, is a container used to hold the sample solution to be tested when the transmittance of the sample solution is tested. It is mainly used in biochemical analyzers. It is an instrument for measuring a certain chemical composition in a solution based on the principle of photoelectric colorimetry. It is widely used in hospitals at all levels because of its fast measurement speed, high accuracy, and small consumption of reagents. , epidemic prevention stations, family planning service stations and other places. The light transmittance requirement of the cuvette is relatively high, which is related to the detection result of the solution in the cuvette. Therefore, in practical applications, the difference between the cuvettes should be minimized, and the repeatabili...

Problems solved by technology

However, in the prior art, there are differences between cuvettes and cuvettes, there are differences between a series of multiple cuvettes, and there are also differences between batches of a batch of multiple cuvettes. There are differences, therefore, the purpose of reducing the differences can not be achieved only by manual visual inspection of the light transmittance of the cuvette
