  • 3.4 K - 500 K temperature range. May be extended down to 2.7 K when used with a rotary pump (not supplied as standard)
  • Cooling to 4.2 K in around 15 minutes
  • Low liquid helium consumption, <0.70 L/h when used with a low-loss transfer siphon
  • Compact and lightweight, 1.5 kg
  • Short working distance, just 2.2 mm
  • Ideal for Quantum Dot applications
  • Extremely low sample vibration, less than 20 nm in optimal conditions
  • Configured for reflectance and transmission measurements
  • Measurement-ready, via 10-pin electrical wiring to the sample
  • Supplied with a MercuryiTC temperature controller
  • 1 year standard warranty

Versatile: The MicrostatHiRes can be fitted with an interchangeable pillar for easy integration into a magnet bore.

Low cryogen consumption: Brings significant benefits in terms of running cost.

Simple: The experimental windows and sample holders can be easily changed.

Easy to use: A range of window materials are available. Please contact your local sales representative for more information.

Software control: Oxford Instruments electronics products are controllable through the software using RS232, USB (serial emulation), TCP/IP or GPIB interfaces. LabVIEW function libraries and virtual instruments are provided for Oxford Instruments electronics products to allow PC-based control and monitoring. These can be integrated into a complete LabVIEW data acquisition system.
