DS 40M is a small roughing (foreline) pump of choice for GC MS instruments, designed for very low noise and low power consumption.

The Agilent DS40M 2m3/hr Rotary Vane Pump is compact, quiet, consumes power frugally, and has a magnetic coupling to eliminate oil leaks.

Key features

• Magnetic coupling makes the pump oil-leak free, thus ideal for a clean laboratory environment and higher pump reliability.
• Low power consumption results in low cost of ownership.
• Low noise creates a pleasant and quiet working environment in a laboratory.
• Integrated antisuckback valve protects high vacuum pump from air inrush.
• Foreline pump’s compact design is ideal for retrofitting.
• Low 10^-3 mbar operation
• Low operating temperature
• Minimal backstreaming at low pressure
• Good pumping efficiency and gas ballast in the low 10^-2 mbar region.
