Flat bottom flasks are suitable for pressureless work. Due to the standard ground joint, plungers can be connected to other ground joint components or closed with ground joint plugs.
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.
