Flask

A flask is a type of laboratory glassware used to hold, mix, and heat liquids during experiments. Key features include: Typically made from borosilicate glass for heat resistance and chemical durability. Comes in various shapes, with common types being Erlenmeyer flask (conical shape with narrow neck) and volumetric flask (pear-shaped with a precise volume mark). The narrow neck helps to reduce spillage and evaporation. Used for mixing by swirling without risk of spilling. Available in different sizes, ranging from a few milliliters to several liters. Often used in titrations, heating liquids, or preparing solutions. Can be stoppered or sealed for storage or reactions requiring containment. Flasks are essential in chemical, biological, and medical laboratories for versatile liquid handling and experimentation.
