Description
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.
Key Features
- High contamination tolerance
- Ultimate vacuum <0.001 Torr
- Low RPM for long service life
Suggested Applications
- Rotary Evaporator
- Vacuum Oven
