Machine capable of controlling liquid flow

Abstract

The invention discloses a machine capable of controlling liquid flow, which comprises a support plate, wherein a touch screen, a test tube frame and a single-chip computer are arranged on the upper surface right end of the support plate, and an opaque sealed box body is arranged on the upper surface left end of the support plate, a column-shaped groove is arranged on the middle part of the upper surface left end of the sealed box body , an injection tube is arranged on the middle part of the upper surface right end of the sealed box body, a hydraulic telescopic rod is arranged on the upper surface of the sealed box body near to the injection tube, the upper end of the sealed box body is connected with the upper end of the injection tube through a connecting plate. A first draft tube is arranged on the left side of the lateral lower end of the injection tube, and a first one-way valve is arranged on the first draft tube. The machine capable of controlling liquid flow has the advantagesof compact structure, easy operation, small space occupation in use, and quantitative take of a reagent. The setting of the sealed box body facilitates the sealed storage of the reagent. The setting of a magnetic flip plate liquid level meter facilitates the observation of liquid level. The setting of lead screw facilitates the clamping positioning of a test tube.

Description

technical field [0001] The invention relates to the technical field of automatic liquid-taking equipment, in particular to a machine capable of controlling liquid flow. Background technique [0002] In the experimental operation of the laboratory, this situation is often encountered, and a certain solution of the same concentration needs to be added to different experimental bottles in the same volume. Especially in the standard substance laboratory, in the production of liquid standard substances, it is often necessary to prepare a large barrel of target standard substance solution in a clean environment. Packed into the smallest packaging unit, this step is called the packaging step. However, when some liquid standard substances are divided into the smallest unit, the volume of the solution is relatively large (>50mL), and the volume of the divided solution needs to be accurately quantified, which requires high precision and high requirements for the packaging environm...
