Reaction device capable of realizing continuous preparation of colloidal gold

Abstract

The invention discloses a reaction device capable of realizing continuous preparation of colloidal gold. The reaction device comprises a raw material mixing vessel, a reaction vessel and a heating device used for heating the reaction vessel, wherein a raw material inlet, a mixed liquor outlet and a stirring device are arranged on the raw material mixing vessel; the inlet end of the reaction vessel is communicated with the mixed liquor outlet; a colloidal gold collecting vessel is arranged at the outlet end of the reaction vessel; the stirring device is used for stirring liquid in the raw material mixing vessel to form the mixed liquor; the duration during which the mixed liquor enters the reaction vessel through the inlet end and the duration during which the mixed liquor flows out of the reaction vessel through the outlet end are matched with the set duration. The overall reaction device provided by the invention adopts a continuous production design on feeding, mixing, reacting and colloidal gold collecting, so that the structure is simple, a complex pipe spraying device is avoided, the production time consumed is short, colloidal gold is produced not only in batches but also on a small scale, and the preparation quantity can be adjusted through an opening and closing valve.

Description

technical field [0001] The invention relates to a reaction device for preparing colloidal gold, in particular to a reaction device for continuously preparing colloidal gold. Background technique [0002] Colloidal gold is a stable, uniform suspension of gold particles suspended in a liquid in a single dispersed state formed after chloroauric acid is reduced to gold. Colloidal gold can be used as a marker for immunohistochemistry, immunodiafiltration, and immunochromatography. In the past 10 years, colloidal gold labeling has developed into an important immunolabeling technique. Colloidal gold immunoassay has been developed in many fields such as drug detection and biomedicine, and has been paid more and more attention by related research fields. [0003] The traditional colloidal gold production process is difficult to well control the nucleation and formation speed in the reduction process, so the colloidal gold particles prepared in this way are not uniform, and the size ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the problems that the existing colloidal gold production equipment cannot carry out small-scale continuous production or traditional continuous production, the prepared colloidal gold particles are uneven, and the equipment structure is complicated, and provide a kind of continuous preparation of colloidal gold. The reaction device has the characteristics of simple structure, suitable for large-scale and small-scale continuous production, short production time, uniform colloidal gold particles, and controllable particle size and shape
