A pipette cleaning device

Abstract

The invention provides a pipette cleaning device, which belongs to the technical field of test auxiliary equipment. The present invention includes a box body, a cover plate, a supporting mesh plate, a pressure mechanism and a communication mechanism. The box body is horizontally provided with a partition block, and the partition block divides the inside of the box body into a first cavity and a second cavity, so The outer side wall of the box body is connected with a liquid inlet pipe and a liquid outlet pipe, the cover plate is covered at the upper end opening of the box body, the supporting mesh plate is horizontally fixed in the first cavity, and the supporting mesh The plate is provided with several first perforations for inserting pipettes, the pressure mechanism can generate negative pressure and positive pressure in the pipettes inserted in the first perforations, and the several first perforations The lower ends of the inserted pipette are all communicated with the first cavity and the second cavity through a communication mechanism. The invention can automatically clean the inside of the pipette and improve the cleaning efficiency.

Description

technical field [0001] The invention belongs to the technical field of experimental auxiliary equipment, and relates to a pipette cleaning device. Background technique [0002] A pipette is a measuring device used to accurately pipette a certain volume of solution. A pipette is a metering-out instrument that is used only to measure the volume of solution it releases. It is a slender glass tube with a bulge in the middle. The lower end is beak-shaped, and a marking line is engraved on the neck of the upper end, which is a sign of the exact volume removed. [0003] At present, the cleaning of pipettes is generally carried out by manual cleaning. This cleaning method has a large workload, is time-consuming and labor-intensive, and easily causes damage to the pipette head and tail; For small-sized pipettes, the inner wall of the tube is relatively thin, and manual cleaning cannot ensure that the inner wall of the tube can be completely washed, and the cleaning effect is poor,...

Problems solved by technology

[0003] At present, pipettes are generally cleaned manually. This cleaning method has a large workload, is time-consuming and laborious, and is likely to cause damage to the tip and tail of the pipette; For small-sized pipettes, the inner wall of the tube is thinner, and manual cleaning cannot ensure that the inner wall of the tube can be completely rinsed, and the cleaning effect is poor, which affects the effect of secondary use.
