Erlenmeyer Flasks

Laboratory use glass Erlenmeyer flasks from Ace, Aldrich, Corning, Duran and Pyrex

The Erlenmeyer flask, also known as a titration or conical flask, is probably the most iconic piece of chemistry glassware. Named for its inventor, Emil Erlenmeyer, this vessel with a wide, flat bottom, conical sides, and cylindrical neck is used similarly to a beaker for measuring, mixing, and heating, but it is better suited to swirling solutions and can easily be held at the neck in one hand. The unique shape of the Erlenmeyer flask also makes it difficult to tip over. It’s also easier to seal an Erlenmeyer flask than a beaker.

Our Erlenmeyer flasks come in common sizes, including 25 mL, 50 mL, 100 mL, 1000 mL (1 L), 2 L, and up to 6 L. Choose from borosilicate glass, polycarbonate, and polypropylene and well-known names like the Pyrex® and Corning® brands or our own Aldrich® chemistry glassware.

We also offer sterile models, Instatherm® flasks that heat up to 250 °C without a separate heating bath, microchemical filtering flasks, and assortment packs of flasks in multiple sizes. Most chemical flasks come singly, but many models are sold in sets of 6 or 12. Click the pricing drop-down to see the price and package size.

Erlenmeyer flask are available in several styles (narrow-mouth, ST joint, aseptic connector, narrow neck, wide neck, baffled, Delong shaker with extra deep baffle, and heavy wall) with various openings (screw cap, stopper top, or joint).

Product pages provide full details for each type of laboratory glassware.

Never use an Erlenmeyer flask under vacuum as a filtering flask.
