Volumetric flasks, also called graduated flasks or measuring flasks, are items of laboratory glassware or plasticware that are calibrated and labelled to hold specified volumes (at a stated temperature) of standard solutions, reagents, solvents or other liquids with a specified tolerance and precision.
- Graduated flasks offer greater accuracy and precision than beakers or measuring cylinders
- They are typically pear shaped, with a flat base and long neck
- They feature a single (or occasionally multiple) ring graduation etched or marked onto the neck defining the specified fill level
- They may also be supplied with a glass or plastic stopper
Volumetric flasks come in a range of capacities from 1mL up to 2L, manufactured from either glass (borosilicate or soda lime), or autoclavable and chemically-resistant plastics such as polymethylpentene, polypropylene or PFA. Glass versions may either be clear glass or amber to hold light-sensitive liquids. Plastic flasks offer the advantages of being break-resistant and may also offer lower extractable profiles.
What's the difference between volumetric flasks Class A and B?
Volumetric flasks may be designated as Class A or Class B. Class A are manufactured to high standards of precision for critical analytical work, whereas Class B flasks offer less accuracy and are therefore more suitable for less demanding applications within education or teaching.
Volumetric flasks are important items in a range of laboratory environments in research and industry. Typical applications include:
- Preparation of standard solutions
- Preparation of series dilutions
- Filling, measuring and then decanting precise volumes of liquid
- Calibrating other containers and devices
