Dean-Stark Setup – Interactive Exercise

Look through the five Dean-Stark scenes. Try to identify any hazards/errors within them. Can you spot the scenario with the fewest errors?

Note, Health and safety errors have been deliberately introduced into the  scenarios for educational purposes.  We do not condone bad lab practice, but allowing students to see such scenarios can help develop hazard perception skills. Best practice may differ in your institution, please discuss this with a local instructor before setting up any glassware.
