Stirring device, dispersion equipment and method for dispersion of latex microspheres

Abstract

The invention discloses a stirring device, dispersing equipment and a method for dispersing latex microspheres, comprising a stirring end and a connecting end connected with a driving element, the stirring end includes a stirring rod and a stirring paddle attached to the side of the stirring rod; the stirring rod The outer end of the stirring rod is provided with a sample drawing inlet hole arranged along the axis of the stirring rod, the outer wall of the stirring rod is provided with a drawing groove, and the side wall of the stirring rod is provided with a sample drawing hole connected with the outside world. . The advantages of the present invention are that it has strong sample dispersion and sample homogenization, can prevent sample components from being damaged, and the stirred and formed samples have good dispersion, high uniformity, and good stirring effect; the dispersion equipment is easy to operate.

Description

technical field [0001] The invention belongs to the field of latex microsphere dispersion equipment, in particular to a stirring device, dispersion equipment and method for dispersion of latex microspheres. Background technique [0002] In the latex-enhanced immune turbidimetric kit, the production and preparation of R2 reagent adopts the classic carbodiimide method in organic chemistry to react the amino group on the antibody or antigen with the carboxyl group on the carboxyl latex microsphere to form an amide bond, so that the antibody or antigen can pass through The chemical bonds are firmly combined on the surface of the microspheres, and the production process and quality control of the reagents are very important; among them, in the cleaning steps after each synthesis reaction, the resuspension and dispersion of the latex microsphere solids precipitated in the buffer system after centrifugation is the reagent production process. As a key quality control point, whether ...

AI Technical Summary

Problems solved by technology

Its disadvantages are: 1. The stirring paddle is a symmetrical structure, and the discrete action of the sample is mainly driven by the paddle, and the edge of the paddle is sharp, which is easy to cause damage to the components of the paddle and affect the production efficiency; 2. The mixing of the sample Uniformity depends on the agitation of the paddle, and the agitation of the paddle through the blade is mainly a large area of ​​agitation, the stirring effect is poor, and the time required for sufficient stirring is long, and it is difficult to form a uniform latex microsphere sample
