In the invention, the sliding ring and the stand column are movably connected to change the height of the whole fixing mechanism, and the sliding column and the sliding rod are movably connected to change the position between the clamping ring and the pipe body.

Description

technical field [0001] The invention relates to the technical field of pipettes, in particular to a highly practical pipette. Background technique [0002] A pipette is a measuring device used to accurately pipette a certain volume of solution. It belongs to a measuring instrument and is only used to measure the volume of the solution it emits. It is shaped like a long and thin glass tube with an enlarged part in the middle. Its lower end is beak-shaped, and a marking line is engraved on the neck of the upper end, which is a sign of the accurate volume obtained. Commonly used pipettes have specifications such as 5, 10, 25, 50, and 75 (mL), and usually have Scaled straight glass tubes are called pipettes. Commonly used pipettes have specifications of 1, 2, 5, and 10 (mL). The volume taken by pipettes and pipettes is usually accurate to 0.01mL. [0003] The procedure for using the pipette is generally to select a pipette of appropriate specifications according to the volume a...
