Disclaimer: We have deliberately introduced health and safety issues into these flash column chromatography 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.
