To use a serological pipette, first, ensure it is clean and attach a pipette bulb or mechanical pipetting device. Insert the pipette tip into the liquid to be transferred. Use the bulb or pipetting device to draw liquid up into the pipette, ensuring that the meniscus aligns with the desired volume on the graduations. Serological pipettes are typically used for variable volumes, so you may need to adjust the amount of liquid by aspirating more or expelling some. To dispense, position the pipette tip over the container and slowly release the liquid, ensuring all the liquid is dispensed. Be cautious to avoid air bubbles, as they can lead to inaccurate readings. After use, dispose of the tip (if disposable) or clean the pipette thoroughly for future use. Serological pipettes are versatile and commonly used in laboratory settings for accurate liquid handling.
