Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipettes, in particular to an antibacterial long filter core pipette for biological experiments. Background Art
[0002] A pipette is a laboratory instrument used to accurately dispense liquids, and is usually used in the fields of biochemistry, biology, and drug research. It can dispense micro or macro volumes of liquids with pipette tips of different capacities, which can improve experimental efficiency and accuracy. There are at least the following disadvantages in the use of existing pipettes: 1. The existing pipette tips often have thinner filter elements inside, but the thinner filter elements have limited filtering effects. When there are more particles in the solution or sample, the thin filter elements cannot protect the pipette and prevent cross contamination; 2. After use, most existing pipettes are placed on gun racks, but the existing gun racks cannot protect the suction end and the pipette tip of the pipette, which can easily cause the suction end to be damaged by collision. Therefore, we have introduced an antibacterial long filter element pipette for biological experiments. Utility Model Content
