Objective
Our objective is to demonstrate how to set up a Schlenk tube and explain what we use it for.
Background
A Schlenk
tube or Schlenk flask is a reaction vessel used mainly in air sensitive chemistry.
This is, chemistry where we observe the reactivity of chemical compounds with
some constituent of air (atmospheric oxygen, water vapor, carbon monoxide…).
It was
invented by Wilhem Schlenk, a German chemist and it is made of borosilicate glass,
which is resistant to thermal shocks. These occur when temperature causes different
parts of an object to expand. When using a Schlenk tube, we might need grease
to join stopcock valves and ground glass to prevent glass pieces from fusing. In
this post we will explain how to set up a Schlenk tube and how to use a Vacuum
line, which consists on a dual manifold with several ports.
