Two-optical-path cuvette structure

Abstract

The invention provides a two-optical-path cuvette structure. Data analysis of a 10MM optical path and data analysis of a 2MM optical path can be finished in the same cuvette, so that the cuvette is high in generality, analysis steps are simple, and testing time is shortened. The two-optical-path cuvette structure comprises a cuvette body and an upper cover, and the upper cover covers the inner edge surface of the cuvette body. The two-optical-path cuvette structure is characterized in that a cavity of the cuvette body has a lower narrow strip structure and an upper wide opening structure; the upper end of the lower narrow strip structure smoothly transits to the lower end of the upper wide opening structure; the width of the inner cavity of the lower narrow strip structure is 10MM, and the thickness of the inner cavity of the lower narrow strip structure is 2MM; the thickness of the inner cavity of the upper wide opening structure is 10MM, and the width of the inner cavity of the upper wide opening structure is 10MM; a surface, which corresponds to the 2MM thickness of the lower narrow strip structure, of the cuvette body is a light passing surface; and a light transmitting surface of the light passing surface of the cuvette body has an inwards concave transparent structure, is higher than the lower narrow strip structure, and extends to the upper wide opening structure.

Description

technical field [0001] The invention relates to the technical field of cell culture devices, in particular to a two-light-path cuvette structure. Background technique [0002] Cuvettes, also known as absorption pools, sample pools, are used to hold reference liquids and sample liquids, and are matched with spectroscopic analysis instruments for quantitative and qualitative analysis of substances. They are widely used in chemical industry, metallurgy, medical treatment, medicine, and food. , environmental protection, power plants, water plants, petroleum and other industries, departments, colleges and universities, scientific research units for testing and laboratory use. [0003] The existing 10MM standard cuvettes and 2MM standard cuvettes are made of PS environmental protection materials. The cavity of the cuvette body is the same space for storing liquid from bottom to top. When it is necessary to analyze one liquid in two For data under the optical path, it is necessary...

Problems solved by technology

[0003] The existing 10MM standard cuvettes and 2MM standard cuvettes are made of PS environmental protection materials. The cavity of the cuvette body is the same space for storing liquid from bottom to top. When it is necessary to analyze one liquid in two For data under the optical path, it is necessary to place the liquid in a 10MM standard cuvette and a 2MM standard cuvette for analysis, which leads to complex analysis steps, long test time, and poor versatility of a single optical path cuvette
