13. SMaRT: Soft Matter Research & Technology Group Using the Vacuum Oven 2 What did Dr. Foudazi do wrong? No gloves No lab coat No goggles No Safe Operating Card Dry ice wasn’t added before turning on the vacuum pump

14. SMaRT: Soft Matter Research & Technology Group Reasons for Adding Dry Ice At low pressures, solvents boil rapidly Solvent vapor skips the condenser, enters the pump, and damages pump gaskets Solvent vapor then exits the pump into the room 3 Image of pump interior.
