The correct tip immersion depth can improve accuracy by up to 5%. The tip should be immersed between 1-2 mm for micro-volume pipettes and up to 3-6 mm for normal-range pipettes, depending on the tip size. If the tip is immersed too far, the volume of gas in the tip is compressed, causing too much liquid to be aspirated. 2. Wrong pipetting angle.Plus Mechanical Pipette.
