ENDo you know how to properly install pipette tips? The correct method is to insert the pipette (device) vertically into the tip of the pipette, and turn it left and right with a little force to make it tightly combined.
When putting the pipette tips on the pipette, many people will knock on the pipette tip box a few times vigorously. The momentary impact force from a tap can become loose and can even cause the scale adjustment knob to get stuck.
Method Of Pipetting
Before pipetting, make sure that the pipette, tip, and liquid are at the same temperature. When sucking liquid, hold the upper part of the pipette with four fingers together, press the button on the top of the plunger rod with your thumb, keep the pipette in a vertical state, insert the tip of the pipette 2-3 mm below the liquid surface, and slowly release the button. Suck up the liquid and stay for 1-2 seconds (the solution with high viscosity can lengthen the residence time), slide the tip out of the container along the wall, and the tip touches the inclined wall when draining.
Before aspirating, you can aspirate and dispense the liquid a few times to moisten the nozzle (especially when you want to aspirate liquids that are viscous or have a density different from water). Finally, press the tip removal push rod to push the tip into the waste tank.
Maintenance of the pipette gun: If it is not in use, it is necessary to adjust the range of the pipette gun to the maximum scale, so that the spring is in a relaxed state, protect the spring, and hang it vertically on the pipette gun rack. After daily use, the surface of the pipette should be cleaned. After cleaning with 10% sodium hypochlorite or 70% alcohol, let it dry naturally. Pay special attention to the tip of the pipette so that no solution (blood) remains.
