What is Schlenk line and glovebox?

Also known as: Schlenk line · Schlenk flask · glovebox

Definition 33.2 University Chemistry — Year 3 · Chapter 33 — Lab Techniques III: Research Practice

A Schlenk line is a double glass manifold, one tube connected to a vacuum pump through a cold trap, the other to a supply of dry inert gas vented through an oil bubbler, with taps that connect each outlet to either. A Schlenk flask has a side arm with a tap for connection to the line. A glovebox is a sealed box filled with inert gas, continuously purified, in which work is done through gloves.

A Schlenk line, schematic: a gas manifold and a vacuum manifold joined by taps; each tap connects its flask either to vacuum or to inert gas. Solvent vapour pumped off condenses in the cold trap before it reaches the pump; the gas leaves through an oil bubbler, which keeps air from flowing back.
