Erlenmeyer Flasks
Erlenmeyer or titration flasks have wide flat bottoms, conical bodies, and tall cylindrical necks. They are named after their inventor Emil Erlenmeyer.
Erlenmeyer flasks are used to contain liquids and for mixing, heating, cooling, incubation, filtration, storage, and other liquid-handling processes.
Their slanted sides and narrow necks allow the contents to be mixed by swirling without the risk of spills, which is useful for titrations and for boiling liquids. The necks can also support filter funnels.
Erlenmeyer flasks may be marked with graduations and have areas where they can be marked or labeled. Made from glass or plastic resin, they are available in a range of volumes/capacities.
The inside of the mouth of Erlenmeyer flasks may be frosted to accommodate a ground glass stopper. Alternatively, a cap or rubber stopper may be used to contain the contents.
Some Erlenmeyer flasks include a side arm (or one can be attached) to enable filtering.
Erlenmeyer flasks can also be used to prepare microbial cultures. Some are fitted with baffles that help maximize gas transfer and further agitate the contents when shaken.
