Pipette Use

Make sure the pipette, tip and liquid to be pipetted are at the same temperature; then rinse the pipette tip 1-2 times with the liquid to be pipetted, especially for viscous liquids or liquids with a density different from water. When pipetting the liquid, immerse the tip of the tip vertically at a depth of 2-3mm below the liquid surface (it is strictly forbidden to insert the tip into the solution), loosen the operating lever slowly and evenly, wait for the tip to inhale the solution, and let it stand for 2-3 seconds. And stick it obliquely on the wall of the container to drain away the excess liquid on the outer wall of the suction head.
