Welch-Ilmvac

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. Pumps can be ordered with an optional exhaust filter to control oil mist.

Welch-Ilmvac

Welch direct-drive rotary vane vacuum pumps achieve vacuum levels down to 1x10-4 Torr (0.1 micron) with flows up to 11.3 cfm. These compact, portable oil-seal pumps are recommended for a variety of laboratory applications. Vacuum system configuration with a cold trap is recommended for use with harsh chemicals. Direct drive pumps are not recommended for filtration, aspiration, drying electrophoresis gels, or other applications requiring sustained operation above 30 Torr.
