Black body flowing colorimetric dish

Abstract

The invention discloses a black body flowing colorimetric dish which comprises a sample chamber (1) with transparent front and rear side surfaces, and is characterized in that a sample injection pipe guide hole (2) and a sample discharging guide hole (3) which communicate with the sample chamber (1) are formed in the sample chamber (1), wherein the lower end of the sample injection pipe guide hole (2) communicates with the bottom end of the sample chamber (1) through a flowing slot (4), and the upper end of the sample injection pipe guide hole (2) communicates with the bottom of a sample injection pipe (5) above the sample chamber (1); the lower end of the sample discharging guide hole (3) is arranged at the top of the sample chamber (1), and the upper end of the sample discharging guide hole (3) communicates with the bottom of a sample discharging pipe (6). Liquid can flow in the sample chamber without a dead corner; a measured sample directly scours a transparent quartz sheet in a measurement process, so that the amount of sample residual liquid is reduced to the lowest; by the adoption of the small-volume sample chamber, the influence of cross contamination is avoided to the maximum extent during continuous measurement, so that the stability and the repetitiveness of measurement are guaranteed, and the sample chamber is high in compatibility.

Description

technical field [0001] The invention relates to the field of biochemical analysis instruments for medical clinical examination, in particular to a flow cuvette used for semi-automatic analysis instruments or full-automatic instruments, specifically a blackbody flow colorimeter capable of analyzing and measuring the concentration of liquid samples Dish. Background technique [0002] In the field of medical clinical laboratory biochemical analysis instruments, when analyzing and measuring the concentration of liquid samples, since the optical path of the droplets is constantly changing during the growth process, it is difficult to ensure the same optical path for different liquids when measuring the spectrum directly through the droplets. As a result, quantitative analysis is difficult, and due to the characteristics and structural limitations of droplet analysis, it is difficult to measure the absorption spectrum of liquid directly through the droplet.
