Infinite Helium technical specifications

STABLE TEMPERATURE

Sensitive samples require a stable environment. Guard against thermal-induced changes with low thermal drift. Precise to 15 mK at base temperature.

AUTOMATED SAFETY ALERTS

  • Water shut off
  • Loss of power
  • Contaminated helium
  • Small leak
  • Major leak
  • Equipment not responding
  • Helium pressure out of range
  • Maintenance due

VERSATILE

Easily move Infinite Helium between multiple continuous flow cryostats.

6 MONTHS+ CONTINUOUS RUN TIME

All components are selected for performance longevity. Don't interrupt your research because of servicing

*Vibration testing was conducted on a production ST-500 cryostat cooled by an Infinite Helium. The stage displacement was measured using a laser Doppler vibrometer with a resolution of better than 10 pm. The vibrometer and cryostat were mounted to a floating optical table located in an environmentally controlled lab with limited foot traffic and low ambient noise, while the Infinite Helium compressor was housed in an enclosed ancillary space in proximity to the optical table.
