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.
