Volumetric
flask is one of the important equipment of laboratory
glassware and is also known as a measuring flask or graduated flask. These
flasks are flat at bottom space and pears in shape used to measure the volume
of a liquid at a particular temperature. It has got a graduation marking on the
neck which is narrow and elongated in shape to measure the volume of a liquid
when it’s filled up. It can be available of various sizes starting from 1ml to
10000ml as per the requirement of process or experiment. It comes in various
shapes but majorly used is narrow neck. It also contains a cap or stopper at its
top of the neck.
Volumetric flask is an
important apparatus used in laboratory to measure the level of liquid to be
used for various processes and so has gained importance in laboratory as its
accuracy is reliable. It is available in different shape and size depending upon
the requirement of process. It has a high resistance capacity to high and low
temperature, is non chemical reactive, transparent and can withstand with high
thermal stress and also has high durability characteristics.
Volumetricflasks are utilized for preparing of chemical solutions,
mixing of two or three chemicals and measuring of partial or full volumetric
pressure and vacuum pressure of a liquid, holding of liquid, cooling, heating
and dissolving of liquid by the various types of industries like hospitals, food
and beverages, pharmaceuticals and chemicals, petrochemicals, life science research
sections, environmental and geological research organizations.
