Laboratory flasks are found in most chemical, biological, clinical and industrial laboratories and a variety of other workplace settings.
Lab flasks are manufactured from glass (borosilicate or soda lime) or plastics such as polypropylene, PMP (polymethylpentene), polycarbonate or PTFE.
Laboratory flasks are available in a range of capacities ranging from 10mL up to 10L. Depending on the type, they may be supplied with a jointed ground glass top, a glass or plastic stopper, a screw top, or simply left plain.
Laboratory flasks are offered in a choice of styles depending on the intended application:
- Erlenmeyer flasks (also called conical flasks), are popular types used for a wide range of purposes. They are graduated and come in narrow-neck or wide-neck versions.
- Büchner flasks are also conical, but have a side-arm which accepts tubing for vacuum applications, and extra thick walls for increased strength for operating under reduced pressures.
- Round-bottom flasks (including retort and Kjeldahl flasks) are used in the chemistry laboratory for reactions, digestions or heating and may have up to three necks for connection to inlet/outlet tubing and other fixtures.
- Volumetric flasks are used for the preparation of standard solutions. They are supplied with precise, one-mark graduations and a stopper, and are designated as Class A or Class B depending on their accuracy. Standard measuring flasks are also offered for less critical measurements.
- Cell culture flasks often have specialised cell-adherent treated surfaces, vented filters and are normally supplied sterile. They may have baffled bases for improved aeration during agitation.
