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!

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.
