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

Embodiment Construction

[0027] The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as Figures 1 to 3 The shown embodiment is a stirring device for dispersion of latex microspheres, comprising a stirring end 222 and a connecting end 221 connected to a driving element, the connecting end 221 is cylindrical, and the driving element adopts a direct connection with the connecting end 221 through a coupling. The connecting end 221 side is provided with four pressure sensors 29 arrayed about the axis of the connecting end 221. In practical application, the pressure sensor 29 is located between the shaft coupling and the connecting end 221 . In addition, a torque sensor can also be used, and the torque sensor can be directly arranged outside the connecting end 221 . The stirring rod 23 rotates synchronously with the driving motor, the driving motor drives the stirring rod 23 to rotate, and the stirring paddle 230 completes ...

Abstract

The invention discloses a stirring device for latex microsphere dispersion, dispersion equipment and a method; the stirring device comprises a stirring end and a connecting end connected with a driving element; the stirring end comprises a stirring rod and a stirring paddle attached to the side surface of the stirring rod; a sample drawing inlet hole formed in the axial direction of the stirring rod is formed in the outer end of the stirring rod, a drawing groove is formed in the outer side wall of the stirring rod, and a sample drawing outlet hole communicated with the sample drawing hole andthe outside is formed in the side wall of the stirring rod. The method has the advantages that the sample dispersing effect and the sample homogenizing effect are high, the components of the sample can be prevented from being damaged, and the stirred and formed sample is good in discreteness, high in uniformity and good in stirring effect; the dispersing equipment is convenient 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 ...
