The Pipette Dispenses The Solution

Hold the pipette or pipette upright, the receiver is tilted, the lower end of the tube is close to the inner wall of the receiver, release the index finger, and let the solution flow down the inner wall of the receiver. Slide the tip of the tube or pipette a few times back and forth against the wall at the receiver point (or rotate the pipette tip against the inner wall of the receiver a few times), and remove the pipette (a small amount of solution remaining at the inner wall of the tube tip) , do not use strong external force to make it flow out, because when calibrating the pipette or pipette, the volume of the remaining solution at the inner wall of the tip has been considered. Except for the one marked with the word "blow" on the tube body, it can be blown out with an ear-washing ball, not reserved).
