Erlenmeyer Flasks

Erlenmeyer or titration flasks have broad flat bottoms, conical bodies, and tall cylindrical necks. Erlenmeyer flasks are used to accomodate 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 chance of spills, which is beneficial for titrations and for boiling liquids. The necks can even support filter funnels. Erlenmeyer flasks could also be marked with graduations and have areas where they can be marked or labeled. Manufactured from glass or plastic resin, they're available in an exceedingly range of volumes/capacities. The inside of the mouth of Erlenmeyer flasks is also frosted to accommodate a ground glass stopper. Alternatively, a cap or rubber stopper could also be used to contain the contents. Some conical flasks include a side arm (or one can be attached) to enable filtering. Titration flasks can even be used to prepare microbial cultures. Some are fitted with baffles that help escalate gas transfer and further agitate the contents when shaken.
