Using the Vacuum Oven SMa. RT: Soft Matter Research & Technology Group 2

Using the Vacuum Oven 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 SMa. RT: Soft Matter Research & Technology Group 2

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 SMa.
