Accessories and Ancillary Equipment

Turbomolecular pumping stations provide a convenient means for evacuating laboratory cryostats and transfer lines to high vacuum levels (< 10-6 Torr). Turbopump stations include a turbopump controller, roughing/backing pump, vacuum gauging, as well as a five foot long flexible pumping line, and valves. The turbopump module utilizes low maintenance ceramic bearings while the mechanical pump includes vibration absorbing mounting. The entire pumping system is mounted on casters for easy movement throughout the laboratory. Two standard configurations are described below. Custom configurations can include larger pump capacities, different gauging, and various inlet flanges.

High Vacuum Pumping Stations

TS-75-W

The new TS-75-W turbopump station includes the same EXT-75DX turbopump, oil-sealed E2M1.5 backing pump, and Wide Range Gauge from Edwards Vacuum as the TP-75 that Janis has been selling for many years now.  The controller on the new pumping station is simpler than the TIC controller on the TP-75, but it still allows the pump to be turned on and off with the push of a single button.  The new TS-75-W is mounted on a smaller cart and the overall system weighs less than the TP-75.

The TS-75-W offers the same performance as the TP-75 at a significantly lower price.

The TS-75-W includes the following features:

  • Turbo pump with nominal 42 liters/second capacity
  • Oil-sealed E2M1.5 backing pump
  • 11 mm OD nozzle built into exhaust
  • All metal mounting frame with rubber feet and cutouts for easy handling
  • Wide range vacuum gauge (atmosphere to 10-8 Torr)
  • Controller with integral air cooler, digital display of turbo speed, and input for one vacuum gauge
  • 5-foot flexible stainless steel pumping line with NW-25 flanges and all fittings necessary for connection to a Janis cryostat
  • Vacuum isolation valve
  • Total weight = 22 kg including pumping line

The TS-75-D offers the same performance as the TP-75-DR at a significantly lower price.

The TS-75-D includes the following features: 

  • Turbo pump with nominal 42 liters/second capacity
  • 0.8 CFM dry diaphragm backing pump
  • Integral silencer built into exhaust
  • All metal mounting frame with rubber feet and cutouts for easy handling
  • Wide range vacuum gauge (atmosphere to 10-8 Torr)
  • Controller with integral air cooler, digital display of turbo speed, and input for one vacuum gauge
  • 5-foot flexible stainless steel pumping line with NW-25 flanges and all fittings necessary for connection to a Janis cryostat
  • Vacuum isolation valve
  • Total weight = 18 kg including pumping line
