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

Two light path cuvette structures

Technical field

The present invention relates to the technical field of cell culture apparatus, be specially two light path cuvette structures.

Background technology

Cuvette, have another name called absorption cell, sample cell, it is used for filling reference liquid, sample liquid, supporting on spectrometric instrument, to material carry out quantitatively, qualitative analysis, be widely used in chemical industry, metallurgy, medical treatment, the test of industry, department and the universities and colleges such as medicine, food, environmental protection, power and water plants, oil, R﹠D institution, chemical examination are used.

Existing 10MM standard colorimetric ware, 2MM standard colorimetric ware, its material is the PS environment-friendly materials, be the identical fluid space of depositing in the cavity of cuvette body from bottom to top, when needs are analyzed respectively the data of a kind of liquid under two kinds of light paths, need respectively liquid to be placed 10MM standard colorimetric ware, 2MM standard colorimetric ware then to analyze, it causes analytical procedure complicated, and the time of test is long, and the versatility of the cuvette of single light path is poor.

Summary of the invention

For the problems referred to above, the invention provides two light path cuvette structures, it can finish the data analysis of 10MM light path, 2MM light path in same cuvette, so that the versatility of cuvette is good, and analytical procedure is simple, has shortened test period.

Two light path cuvette structures, its technical scheme is such: it comprises the cuvette body, loam cake, described loam cake mounts cover in the Inner of described cuvette body edge face, it is characterized in that: the cavity of described cuvette body is bottom fillet structure, the wide mouth structure in top, the upper end of described bottom fillet structure seamlessly transits to the lower end of the wide mouth structure in described top, the width of described bottom fillet structure inner chamber is 10MM, thickness is 2MM, the inner chamber thickness of the wide mouth structure in described top is 10MM, width is 10MM, corresponding of the thickness 2MM of the bottom fillet structure of described cuvette body is logical light face, the transparent surface of the logical light face of described cuvette body is the transparent configuration of indent, the height of described transparent surface is higher than the height of described bottom fillet structure, and extending to the wide mouth structure in top, the surface of contact with described cuvette body of described loam cake is provided with two-layer at least tongue and groove enclosed construction.

After using structure of the present invention, because the cavity of cuvette body is bottom fillet structure, the wide mouth structure in top, the upper end of described bottom fillet structure seamlessly transits to the lower end of the wide mouth structure in described top, and the width of described bottom fillet structure inner chamber is 10MM, thickness is 2MM, the inner chamber thickness of the wide mouth structure in described top is 10MM, width is 10MM, after liquid is poured the cavity of cuvette body into, enter into bottom fillet structure and so that reach enough liquid levels, the light path of its underpart fillet structure is 2MM, the light path of the wide mouth structure in top is 10MM, it can finish the 10MM light path in same cuvette, the data analysis of 2MM light path, so that the versatility of cuvette is good, and analytical procedure is simple, has shortened test period.
