  • Wide range of free-air capacities to match specific applications
  • Positive pressure oil system ensures proper lubrication and prevents oil starvation at high gas loads
  • Fast acting inlet valve protects internal components against oil and air contamination if the pump stops while under vacuum
  • Gas ballast valve limits internal condensation—use pump when condensable vapors are present
No need to purchase both single- and dual-stage pumps! Dual-mode pumps offer a choice of high-vacuum (HV) mode or high-throughput (HT) mode in one pump. Pumps also feature three-position gas ballast control. Set the pump to HV mode with gas ballast off for use with electron microscopes or mass spectrometers; set it to HT mode with gas ballast fully open for use with gel dryers, vacuum ovens, or rotary evaporators. What’s included: vacuum oil. Pumps do not include a power cord.Power cord and plug are included with the pump.
