Disclaimer: We have deliberately introduced health and safety issues into these Dean-Stark apparatus scenes for educational purposes. We do not condone bad lab practice, but allowing learners to see such scenarios can help develop hazard perception skills and a general appreciation of health and safety. We have not highlighted all hazards in these exercises. Best practice may differ in your institution so please discuss this with a local instructor before setting up any apparatus.
