Tips for using pipette tip cartridges

The pipette tip box is made of high-purity virgin PP material, designed to produce a more coaxial, rounder, more pointed tip (nozzle, pipette tip) open end, this feature has the advantage of helping a drop of liquid to be more easily separated from the tip without adhering to the edge of the opening, especially for small volume pipetting operations
.
BUNSEN Bunsen uses polypropylene material, which can be sterilized at high temperature, autoclaved, and the inner wall of the inner wall is siliconized without sticking to liquid to ensure the accuracy of specimen transfer
.
Tips for using the pipette tip box: 1.
Install the tips: After entering the tip at the bottom of the sleeve, if it is operated in the tip box, shake left and right or turn slightly for 1-2 seconds while gently pressing down; If using bulk tips, turn the tips slightly for 1-2 seconds while gently applying pressure to the pipette by hand
.
If this does not achieve the ideal seal, the tip and pipette need to be checked
.
2.
About residence time: For large-range pipetting and pipetting with a viscosity significantly higher than that of water samples, after releasing the thumb when aspirating, the tip must stay in the liquid for 3-5 seconds before it can be removed 3.
Storage: After use, it must be adjusted to the maximum capacity, and then hung (it can be hung on a special bracket or on the metal crossbar of the experimental bench cabinet).

Skilled operation of the use of the method must master the above requirements
.
4.
Control the speed of suction: During the process of suction, the downward pressure of the thumb must be slowly reduced so that the liquid rises evenly and slowly in
the suction head.
5.
Control the depth and angle of aspiration: (1) Depth requirements for tip immersion: The depth of aspiration needs to ensure that the required pipetting volume is reached; Keep the outer wall of the tip in contact with as little liquid as possible
.
(2) Pipetting angle: It must be kept upright during the pipetting process
