Description

A multi-pipette cleaning device

technical field

The utility model relates to biological experiment equipment, in particular to a cleaning device for multiple suction pipes.

Background technique

The full name of the pipette is "grading pipette", also known as a graduated pipette. It is a measuring-out glass measuring vessel with a graduation line, which is used to pipette a non-fixed amount of solution. The specifications and capacities are: 0.1ml, 0.2ml, 0.5ml, 1ml, 2ml, 5ml, 10ml, 15ml, 20ml, 25ml, 50ml. The graduated straw is a precision liquid measuring instrument. The lower end is a pointed tip with a small hole, and the middle part is a uniform cylindrical shape. The upper end of the pipette with a large measuring range is constricted and narrowed, and the ear washing ball is used to absorb liquid from the upper end.

Generally, for strict tests during cleaning, soak in lotion first, then rinse repeatedly with tap water, and then rinse repeatedly with distilled water.

The cleaning process of existing pipettes has many disadvantages: processes such as lotion soaking and tap water rinsing require different containers, and must be repeatedly transferred between different containers; the lumen of the pipette is narrow, it is difficult to enter the liquid to achieve the purpose of cleaning, and it is easy to clean Not clean; the pipette after cleaning needs to be placed on the pipette rack, which is easy to be polluted; the cleaning process is cumbersome, and the tip of the pipette is easy to be damaged by changing the container back and forth, and the measuring function will be lost.
