Erlenmeyer Flasks

Erlenmeyer flasks carry a distinctive conical shape and narrow neck and are suitable for various laboratory applications, including mixing, storing, and dissolving solid and liquid substances.

Erlenmeyer flasks carry sterile properties to reduce the risk of cross-contamination between sample types. Erlenmeyer filter flasks offer disposable options with marked graduations. Baffled Erlenmeyer flasks are suitable for shaker culture applications. Models available from Thomas Scientific include vent cap options for applications requiring a sterile gas exchange. Find baffled Erlenmeyer flask, Erlenmeyer filter flask, and side arm flasks to accommodate a range of applications. Manufactured of the highest quality materials, including polymethyl pentene (PMP) and polypropylene (PP), Erlenmeyer flasks are an excellent break-resistant alternative to using glass flasks.

Multiple sizes, including marked graduations such as 15mL or 50mL for easy measuring solutions, are available. Baffled flasks are individually packaged for easy storage and handling within the lab.

What is the Erlenmeyer flask used for?

The Erlenmeyer flask is a versatile laboratory vessel for mixing, heating, and storing liquids. Its conical shape minimizes spillage and splashing during mixing, making it ideal for tasks like titrations, preparing solutions, or culturing microorganisms. The narrow neck reduces evaporation and allows stoppers for secure containment, while its broad base ensures stability on lab surfaces. Scientists and researchers use Erlenmeyer flasks in chemistry, biology, and microbiology for both small-scale experiments and large-scale media preparation.

What is the function of a filter flask in chemistry?

A filter flask, also known as a Buchner flask or vacuum flask, is used in chemistry to facilitate filtration processes under reduced pressure. Its thick-walled design withstands the vacuum created when connected to a vacuum pump or aspirator. When used with a Buchner funnel and filter paper, the sidearm outlet allows air to draw out, speeding up the filtration process. Filter flasks separate solids from liquids, purify samples, or dry precipitates in analytical and preparative chemistry.
