Welch Vacuum 1400B-01 DuoSeal Vacuum Pump, 580 Pump RPM

DuoSeal Vacuum Pump, 580 Pump RPM

DuoSeal Vacuum Pumps are known for their ruggedness world-wide. These pumps have large oil reservoirs to dilute contaminants. Low pump rpm to reduces friction and wear while minimizing reservoir temperature to lessen chemical reactivity. Pump can be ordered with an optional exhaust filter to control oil mist.

Features

• High contamination tolerance
• Ultimate vacuum <0.001 Torr
• Low RPM for long service life

Applications

• Rotary Evaporator
  • Rotary evaporators are typically used to remove solvents following chemical reactions. Combined with gentle heat from the evaporator bath, controlled vacuum is used to bring solvents to boiling or near-boiling. Efficient solvent distillation requires vacuum balanced to achieve sufficient pressure reduction and molecular flow without losing sample or overrunning the condensing capabilities of your rotovap.
• 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.
