A volumetric flask, often known as a vol flask, is a form of glassware used in laboratories. It is used to retain and measure precise liquid amounts. It has a Florence flask-like form, but a flatter bottom. A stopper can be used to seal the aperture at the top of a volumetric flask's tall, thin neck. To indicate how much to fill the flask, there is a line on the neck. The sizes of volumetric flasks range from a few millilitres to many litres. They're frequently employed to create liquid solutions. Buy now!
