Vacuum is required for a number of laboratory procedures. This is most routinely achieved in the laboratory by the use of vacuum pumps. In addition to working at low pressures, vacuum pumps can also be used to enable rapid changing of the atmospheres in a reactor or flask by evacuation and backfilling.
1. Use of Personal Protective Equipment
2. Use of Proper Tubing and Equipment
Operations requiring vacuum have multiple hazards associated with them. Vessel implosion can lead to flying glass and other materials, the release of chemicals to the working environment, and potentially fire due to the condensation of liquid oxygen. Vacuum operations should be set up properly and only operated after potential risks have been identified and properly mitigated.
