WebA Schlenk Line is a tubular glass apparatus commonly used in chemistry or material laboratory research to carry out experiments under a vacuum and an inert atmosphere (like nitrogen or argon). It is used when samples are sensitive to air/moisture and the vacuum is also often used to remove the last traces of solvent from a sample. A Schlenk ...
