This website provides a link to a simple downloadable program that introduces students to a Schlenk line through a series of short animations. It is designed for Windows (does not appear to work on Windows 8 or on Macs). While a bit rudimentary, it does a nice job of showing students the basic setup, discussing safety concerns with the liquid nitrogen trap, and outlining the general procedure for starting up and shutting down the Schlenk line.
After viewing the program, a student should be able to:
- describe the three major components of a Schlenk line (liquid nitrogen trap, vacuum manifold, and nitrogen manifold) and understand how they are connected,
- understand the safety concerns related to use of the liquid nitrogen trap,
- demonstrate how to operate a 3-way valve to connect a flask to the nitrogen or vacuum manifolds, and
- know the correct order of operations for setting up and shutting down a Schlenk line,
To install the program, download the .zip file from the listed website. Unzip the file, open the Disk 1 folder, and double-click "setup.exe". The program will work on an individual PC or across a network.
I have students download, install, and view the program as part of their pre-lab exercise for our laboratory experiment involving Schlenk line work in our 300-level inorganic course. They are also required to answer a few related questions as a part of the assignment (Describe any specific safety concerns for working with a Schlenk line; Outline the steps required to set up the Schlenk line for use).
I would think the program would also be very a useful resource as an introduction or refresher for research students using Schlenk line techniques.
