An OpenSTEM laboratory
school providing you with 24 hours of ‘hands on’ experience with several widely used
techniques in chemistry. Techniques include pipetting, titration, solvent
extraction, heating under reflux, crystallisation, filtration, melting point
determination, TLC, UV-Vis analysis and IR spectroscopy. The laboratory
protocols are designed to develop good laboratory practice (GLP).
To gain this badge, you
must have successfully participated in all aspects of practical training/techniques at the OpenSTEM ‘Laboratory skills for chemistry’ Laboratory School (SS002/SS021), and demonstrated awareness
of and working to relevant health and safety guidance, including completion of
the pre-laboratory test and the associated guide Chemistry: a practical subject.
