Problems solved by technology

As a result, there are disadvantages. First, the inner corner of the biochemical cup is not easy to clean, and the automatic cleaning brush is not easy to clean to the right angle, resulting in the test liquid remaining in the inner corner of the biochemical cup and mixing with the subsequent injected test liquid, causing cross contamination and affecting the test accuracy.
The second is that the liquid siphon is easy to be generated at the right angle of the inner angle, which makes the test liquid level drop, causing the liquid level to leave the position of the test spot
Affect the test accuracy

Embodiment 1

[0026] Such as figure 2 , a glass biochemical cup, the corners between two adjacent sides of the inner wall and the corners between the sides and the bottom surface are arc-shaped. The curvature radius R of the arc is 2-3 mm. The shape of the glass biochemical cup is a cuboid. The glass biochemical cup is made of glass tubes as raw materials, which are molded after being heated and sealed at the back, so that all corners of the inner wall of the glass biochemical cup are arc-shaped.

[0027] The detailed process of the glass biochemical cup preparation method is:

[0028] (1) Rectangular tube making: Manufacture a tube-making mold that meets the requirements, such as image 3 As shown, the pipe-making mold includes a rectangular inner mold and a rectangular outer mold, and the corner between every two adjacent sides of the rectangular inner mold is in the shape of a convex arc. The function of the rectangular inner mold is to control the inner diameter and inner shape of ...

Abstract

The invention discloses a glass biochemical cup and a preparation method thereof. The corners of every two adjacent side faces of the inner wall of the glass biochemical cup and the corners between the side faces and the bottom are shaped like an arc. As the corners in the glass biochemical cup are shaped like an arc, no cleaning blind corners exist and the glass biochemical cup is convenient for cleaning without any test solution residue, thereby avoiding cross contamination to influence test accuracy and avoiding liquid siphon caused by right-angle corners to affect the test accuracy. The existing biochemical cups are produced by bonding a plurality of glass pieces, thus the production efficiency is low and the possibility of errors is high. In the preparation method of the glass biochemical cup, glass tubes are adopted as dies for raw materials, thus the method is simple and easy to operate.

Description

technical field [0001] The invention belongs to the field of optical instruments, and is an improvement to a method for preparing a glass cuvette for spectral analysis, and is especially suitable for a method for preparing a glass biochemical cup with a small capacity. Background technique [0002] The glass biochemical cup used to hold the test solution on the automatic biochemical instrument used in the hospital laboratory, etc. is a kind of glass biochemical cup with closed sides and bottom, with a hollow cavity, in which the two-sided glass used for transmitting light is transparent, not used for transmission Light glass is opaque, a glass cuvette with an upper opening. An analysis and test of dozens or even hundreds of samples requires the same number of biochemical cups. After the test is completed, the biochemical cups containing the test solution must be automatically cleaned before replacing the samples. Since the current biochemical cup is made of several pieces o...
