Techniques & Standard Operating Procedures

Collected here are guides and standard operating procedures (SOPs) we follow in SMC. Our goal is to do better and safer chemistry with minimized equipment wear and tear.

In building this set of resources we drew heavily on the excellent initiative The Safety Net, founded by Prof. Alex Miller of UNC Chapel Hill and Prof. Ian A. Tonks of the University of Minnesota - Twin Cities. A big thank you to them and their teams!


Acid bath SMC's guide to prepare and handle an acid bath for cleaning glassware

Ammonium fluoride from U. of Michigan, some guidelines on safely working with NH4F

Aqua regia a solution for cleaning glassware when normal solvents don't work

Base bath preparation and usage

Changing vacuum pump oil pump oil should be changed twice at year at least

Changing gas cylinders from The Safety Net how to safely work with gas cylinders and regulators. Note that special precauations are needed for toxic gases! (e.g., CO)

Cleaning glassware for normal cleaning of glassware

Dealing with liquid oxygen from The Safety Net how to recognize and safely deal with unexpected liquid oxygen, for example in a vacuum trap

Degassing solvent adapted from The Safety Net

Electrochemistry troubleshooting from The Safety Net

Electrode polishing from The Safety Net it is time to make some figure-8's

GC-MS details on SMC's GC-MS instrument

Glovebox the user guide for SMC's argon-filled glovebox

Guide to Pipettting by Gilson for correct autopipette use

NMR basic guidelines on SMC's 400 MHz NMR spectrometer

Piranha a very effective, yet dangerous, cleaning solution which should only be used when absolutely necessary - aqua regia is safer to prepare as it does not become very hot during mixing

Pyrophoric chemicals from The Safety Net on how to safely work with pyrophorics

Rotovaps how to use the SMC rotovaps

Transport of chemicals and solvents SMC's guidelines how to transport chemicals and solvents inbetween labs on different floors

Vacuum transfer of liquids from The Safety Net on how to transfer liquids using a Schlenk line

Waste Disposal SMC collects solid contaminated glass and non-glass waste in yellow bins and liquid waste in 25 L plastic drums. Please see the PDF guidelines for how to dispose of waste in SMC, and posted instructions by the waste fume hood.

If you have unique waste, please see UU's published guidelines (på svenska).

Please recycle non-contaminated waste! SMC has a recycling collection point in the corridor for non-hazardous recyclables like packaging materials and metal. When this collection area becomes full, please take the recycling to the Ångström recycling center in K1 of House 5 (no special card access needed). This is the responsibility of all SMC members. The Ångström recycling center can also accept batteries, light bulbs, and other common materials.
