How do you properly use a pasteur pipette for accurate and precise liquid transfer in the laboratory?

To properly use a pasteur pipette for accurate and precise liquid transfer in the laboratory, first, ensure the pipette is clean and dry. Next, draw the liquid into the pipette by gently squeezing the bulb and placing the tip into the liquid. Release the bulb slowly to draw in the desired amount of liquid. To dispense the liquid, hold the pipette at a slight angle and gently press the bulb to release the liquid drop by drop. Be careful not to introduce air bubbles, and always handle the pipette with care to avoid spills or contamination.
