What is schlenk flask?

A Schlenk flask is a type of reaction vessel used in chemistry for air-sensitive reactions. It is made of glass and features a side arm that can be connected to a vacuum or inert gas source using a stopcock. This allows for the manipulation of the atmosphere inside the flask, enabling reactions to be carried out under inert conditions.

Schlenk flasks are commonly used in organic and inorganic chemistry for reactions such as Schlenk line techniques, organometallic synthesis, and catalysis. They are especially useful for reactions involving sensitive or reactive compounds that must be protected from air or moisture.

In addition to the side arm, Schlenk flasks typically have a ground glass joint on the neck for connecting to other pieces of glassware or equipment. They are available in a range of sizes, from small-scale reactions to larger reactions requiring more volume.

Overall, Schlenk flasks are an essential piece of equipment for any laboratory working with air-sensitive compounds, allowing for safe and efficient handling of reactions under controlled conditions.
