Dilution apparatus capable of simplifying double dilution operation

Abstract

The invention discloses a dilution apparatus capable of simplifying double dilution operation. The dilution apparatus is formed by successively connecting an inlet pipe, multiple intermediate pipes and a tail pipe which all comprise slantly-arranged connecting pipes and vertically-arranged hybrid pipes. A rotary switch is arranged at the junction of each connecting pipe and a corresponding hybrid pipe. In the connected intermediate pipes and the tail pipe, pipe volume from the rotary switch of any hybrid pipe to the junction of the last hybrid pipe and the corresponding connecting pipe is equal; and the volume is also equal to pipe volume from the rotary switch of the inlet pipe to a quantitative standard line. The lower end of each hybrid pipe is successively connected with a piston, a latex tube and an outlet pipe. A downcomer is arranged at the center of the piston along its length direction. A glass bead for controlling outflow of a liquid is arranged in each latex tube. By the adoption of the apparatus, a loading step during double dilution is simplified effectively. The defect that operations are tedious and errors are easily caused is overcome. In addition, the apparatus also has advantages of accurate dilution, simple operation and the like.

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...
