A serological pipette is a graduated cylindrical laboratory tool (glass or plastic) used to accurately transfer milliliter volumes of liquid, typically
from 1 to 50 mL. It is commonly used for tasks such as mixing solutions, cell culture work, and reagent transfer. Serological pipettes feature
measurement markings along their length and may be sterile disposable versions or reusable sterilizable ones.
