Chemtech Scientific Vacuum Engineers, Chemists and Vacuum Pump Mechanics consider the following factors in selecting the perfect performing and lowest maintenance Short Path Distillation vacuum pumps: Partial pressure of solvent/ material to be fractioned out of product Ultimate pressure of vacuum pump Latent heat of vaporization Temperature of heat bath Temperature of condenser or cold trap Temperature of circulating bath Volume of distillation flask Solvent expansion ratio Pumping speed of vacuum pump Chemical compatibility of product fractions and wetted parts of system and pump Your process can be accomplished with a higher maintenance oil sealed rotary vane pump or a Dry, oil free PTFE Diaphragm pump. Your lab will enjoy many benefits when processing product with a clean, dry, Chemical Duty vacuum pump and eliminate oil changes and the risk of oil migrating to contaminate your product/samples. However, Dry high vacuum pumps are considerably higher cost. A mechanical oil sealed pump will also do the job. Make your selection below.
