Applications

• Vacuum Oven
  • Select a pump for your vacuum oven based on the size of the oven and the nature of the vapors emitted. Select from standard duty pumps for aqueous vapors or choose a PTFE diaphragm vacuum pump for resistance to harsh chemicals. Thorough drying of certain samples requires a deep vacuum, often produced by an oil-seal pump; a cold trap is required to protect the pump. Where sample properties permit, a lesser vacuum dry pump can work well.
