How to use pipette bulb?

To use a pipette bulb, start by attaching it to the pipette. Immerse the tip of the pipette into the liquid, and squeeze the bulb gently to expel the air. Release the bulb slowly to create suction, and allow the liquid to be drawn into the pipette. Be sure to hold the pipette vertically and ensure no air bubbles are drawn in. When the desired amount of liquid is in the pipette, remove the bulb and proceed with dispensing the liquid into the receiving container. Always ensure you are dispensing accurately, keeping the meniscus in mind.
