Schlenk lines are versatile pieces of laboratory equipment that enable the safe and convenient manipulation of air- and moisture-sensitive compounds. First pioneered in 1913 by Wilhelm Schlenk, the apparatus and techniques used today have evolved considerably, allowing more challenging and sensitive synthetic chemistry to be carried out on a routine basis. This tutorial, which is based on The Schlenk Line Survival Guide, aims to showcase and explain the key technical aspects of Schlenk line chemistry through a series of illustrated guides. It is hoped that this practical guide provides a useful introductory resource and teaching tool for beginner Schlenk line users, as well as a convenient go-to aid for chemists of all proficiency.
