A dilution device capable of simplifying the ratio dilution operation

Abstract

The invention discloses a dilution device capable of simplifying the ratio dilution operation, which is composed of a water inlet pipe, a plurality of intermediate pipes and a tail pipe connected in sequence, and the water inlet pipe, a plurality of intermediate pipes and the tail pipe all include connecting pipes arranged obliquely and the vertically arranged mixing tube, the connection between the connecting tube and the mixing tube is equipped with a rotary switch; in the connected middle tube and tail tube, the upper edge of the rotary switch of any mixing tube is connected to the connecting tube to the previous mixing tube The volumes in the tubes are equal, and the volume is also equal to the volume in the tubes from the upper edge of the rotary switch on the water inlet pipe to the quantitative standard line; the lower end of each mixing tube is connected with a piston, a latex tube and a liquid outlet tube in turn; the center of the piston A lower liquid pipe is arranged along the length direction, and glass beads for controlling liquid outflow are arranged in the latex pipe. The device effectively simplifies the steps of adding samples for doubling dilution, not only overcomes the shortcomings of cumbersome operation and prone to errors, but also has the advantages of accurate dilution and simple operation.

Description

technical field [0001] The invention belongs to the field of experimental equipment, and mainly relates to a dilution device capable of simplifying the ratio dilution operation. Background technique [0002] In the teaching and scientific research of physics, chemistry, biology and other fields, a large number of liquid reactions are involved. In order to detect some indicators qualitatively or quantitatively, it is necessary to use a variety of reaction test solutions with different concentrations during the reaction process. Especially in the field of biology, such as antigen antibody agglutination test, precipitation test, hemagglutination test, hemagglutination inhibition test, and research on the minimum inhibitory concentration and minimum bactericidal concentration of antimicrobial drugs, etc., all require liquids such as antigens, antibodies or drugs Doubling dilutions were used for the determination of test results. The traditional dilution method needs to add a sa...
