Hint: When you're done making a starter and want to get the stir bar out for a second starter or before you pitch, use a rare earth magnet on the outside of the flask to pull it up the side. While there's no harm in accidentally dumping the stir bar into the fermenter (we've all done it), you will inadvertently forget it's in there and end up pouring it down the drain when you go to clean the fermenter. That's why it's always good to have spares. ;)
Many processes in the lab involve the handling and storage of chemical substances. To handle these substances, you need glassware to contain, mix, and store these substances. One of the most common glassware found in a lab is the Erlenmeyer Flask. These flasks are typically used in chemistry and biology labs.
An Erlenmeyer flask has a broad flat base and a conical body that tapers upward into a cylindrical neck. It is used in labs for mixing, cooling, heating, filtrating, incubating, and storing liquids. These flasks are named after Emil Erlenmeyer, who was the German chemist that created these flasks. The flasks are also known as conical flasks or as titration flasks.
Erlenmeyer flasks have wide bases and narrow necks.[3] They may be graduated, and often spots of ground glass or enamel are used where they can be labeled with a pencil. It differs from the beaker in its tapered body and narrow neck.[4] Depending on the application, they may be constructed from glass or plastic,[5] in a wide range of volumes.[6]
The mouth of the Erlenmeyer flask may have a beaded lip that can be stopped or covered. Alternatively, the neck may be fitted with ground glass or other connector for use with more specialized stoppers or attachment to other apparatus. A Büchner flask is a common design modification for filtration under vacuum.
The slanted sides and narrow neck of this flask allow the contents of the flask to be mixed by swirling, without risk of spillage, making them suitable for titrations by placing it under the buret and adding solvent and the indicator in the Erlenmeyer flask.[7] Such features similarly make the flask suitable for boiling liquids. Hot vapour condenses on the upper section of the Erlenmeyer flask, reducing solvent loss. Erlenmeyer flasks' narrow necks can also support filter funnels.
The final two attributes of Erlenmeyer flasks make them especially appropriate for recrystallization. The sample to be purified is heated to a boil, and sufficient solvent is added for complete dissolution. The receiving flask is filled with a small amount of solvent, and heated to a boil. The hot solution is filtered through a fluted filter paper into the receiving flask. Hot vapors from the boiling solvent keep the filter funnel warm, avoiding the premature crystallization.
Erlenmeyer flasks are also used in microbiology for the preparation of microbial cultures. Erlenmeyer flasks used in cell culture are sterilized and may feature vented closures to enhance gas exchange during incubation and shaking. The use of minimal liquid volumes, typically no more than one fifth of the total flask volume, and baffles molded into the flask's internal surface both serve to maximize gas transfer and promote chaotic mixing when the flasks are orbitally shaken. The oxygen transfer rate in Erlenmeyer flasks depends on the agitation speed, the liquid volume, and the shake-flask design.[9] The shaking frequency has the most significant impact on oxygen transfer.[10]
To impede illicit drug manufacturers, the state of Texas previously restricted the sale of Erlenmeyer flasks to those who have the requisite permits.[14] On September 1, 2019, SB 616 amended the law so that permits are no longer required, but accurate inventory of this and certain other pieces of lab equipment must still be maintained, loss or theft must still be reported, and the owner must still allow audits of their records and equipment to be made.[15]
Corning closed system Erlenmeyer flasks will and enhance the productivity of your shaker culture operations when adding or removing medium and cells. Flask is made from optically clear polycarbonate and is preassembled with an aseptic transfer cap. Unit is sterilized by gamma radiation.
Erlenmeyer Conical Flasks from Narrow Neck Borosilicate Glass is perfect for a wide range of laboratory experiments. These heavy-duty flasks are made from durable and chemically-resistant glass that offers reliability and durability for a range of applications. Each flask features a narrow neck for easy pouring and a uniform cylindrical shape for better temperature control.
This flask is conical in nature and made from borosilicate glass. The sturdy design features a beaded rim, graduations (mL and %) and a matte white marking spot for easy identification. Image may vary. 781b155fdc
