Problems solved by technology

[0002] When conducting chemical experiments in the laboratory, it is necessary to mix the two solutions through the liquid extractor. The dropper is often used. Due to the low length of the dropper, if you encounter a deep container, the length of the general dropper is not enough, and it will not be smooth. The liquid is taken out, and the general liquid taker is in the shape of a straight cylinder, which is prone to slippery hands when in use

Abstract

The invention discloses a laboratory liquid extractor, comprising a first connecting pipe, a second connecting pipe and a third connecting pipe, the second connecting pipe is an arc tube, one end of the arc tube is connected to the first connecting pipe, The other end of the arc tube is connected to the third connecting pipe, the first connecting pipe is parallel to the third connecting pipe, the first connecting pipe, the second connecting pipe and the third connecting pipe are connected, and there is a movable cavity inside the first connecting pipe , the first connecting pipe, the second connecting pipe and the third connecting pipe are all provided with an air suction channel, a liquid taking pipe is arranged in the movable chamber, a sealing ring is arranged at the top outer end of the liquid taking pipe, and a sealing ring is arranged in the third connecting pipe. a suction device. The present invention has a simple structure. When in use, the length of the liquid-taking pipe can be adjusted according to the depth of the container, which is more conducive to liquid taking. In addition, the present invention is provided with a U-shaped tube, so it can be easily handled when taking liquid, without As for slipping, the shape is novel, the design is reasonable, and the use is more comfortable.

Description

technical field [0001] The invention relates to a laboratory-used liquid extractor. Background technique [0002] When carrying out chemical experiments in the laboratory, it is necessary to mix the two solutions through the liquid extractor. The dropper is often used. Due to the low length of the dropper, if you encounter a deep container, the length of the general dropper is not enough, and it will not be smooth. The liquid is taken out, and the general liquid taker is in a straight shape, which is prone to slippery hands when in use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a laboratory liquid taker with adjustable length, more comfortable handling, more stability and more novel design. [0004] The present invention is achieved through the following technical solutions: a laboratory liquid extractor, comprising a first connecting pipe, a second connecting pipe and a third connecting pipe, the second c...
