< 300 mK familySample-in-vacuum 3He refrigerator - HelioxVT
Versatile: Provides a cryogenic environment (6 K) ideal for sensitive optical and electrical measurements in magnetic field (up to 5 T).
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.
