  • Speed Display Actual rotor speed will be within 1% of the set speed
  • time, 0 to 99 h 59 min; HOLD for longer runs
  • Electrical 208/220/240 V nominal power, AC, 50 or 60 Hz, 30A (circuit breaker) on/off, Single Phase
  • Dimentions, H x 1295 mm (51 in.) – W x 978 mm (38.5 in.) – D x 699 mm (27.5 in.)

Interlocks prohibit drive operation in the event of a missing or damaged over-speed disk, an over-speed condition, excessive rotor temperature, loss of chamber vacuum, an open chamber door, an overheated drive, an imbalanced rotor, or interruption of the oil supply to the seal assembly of the CF-32 Ti rotor. Diffusion pump in tandem with a mechanical vacuum pump reduces chamber pressure to below 5 microns (0.665 Pa). Digital readout indicates accumulated w² t to three significant figures and exponential notation. Can be used to terminate a run at a reselected value.


If you are a bargain hunter please give us a call, we always have instruments in stock, which have not been refurbished and can be sold as is in working condition.
