Cuvette light transmittance tester

Abstract

The invention discloses a cuvette light transmittance tester. The tester comprises a pedestal, and a reaction disc, a reaction tank, a driving device, a luminescence device, a photoelectric receiver and a shell cover which are arranged on the pedestal; the reaction disc is in rotating connection with the pedestal through the driving device, and the edge of the reaction disc is circumferentially connected with a plurality of cuvette couplings forming a ring; the reaction tank is circumferentially provided with a ring of annular grooves with upward openings, and the cuvette couplings are positioned in the annular grooves; the luminescence device is positioned in the reaction tank, light beams emitted by the luminescence device go through the cuvette couplings and are received by the photoelectric receiver, and the photoelectric receiver is electrically connected with the data analyzer of the tester through a lead; and the edge of the shell cover is connected with the edge of the pedestal, and the cuvette couplings are positioned in the perforated position of the top surface of the shell cover. The cuvette light transmittance tester adopting the above structure reduces differences in cuvettes, couplings and batches, so the biochemical analysis result using the cuvettes is 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...

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
