Cryotechnology
Cryogenic cooling solutions from bath cryostats to closed-cycle systems
Magnet Cryostats
Superconducting magnet cryostats for high-field SPM. Bath systems house 1D, 2D, or 3D magnets up to 22 T; a dry UHV magnet offers 3 T standard, up to 7 T. SPM / STM / AFM compatible.
Continuous Flow Cryostats
Continuous flow cryostats, supplied with LHe or LN₂, for variable-temperature experiments in UHV and optical setups. Temperature range from below 3 K to 500 K with cool-down in minutes. Cold-finger (Konti UHV) and top-loading exchange-gas (Konti Spectro) designs.
Bath Cryostats for SPM
Liquid helium bath cryostats for scanning probe microscopy, where ultra-low vibrations are required. Temperature range 2.2 K to 4.2 K; 1 K pot and Joule-Thomson versions reach 1.0 K with helium-4.
Dry 1K Top Loader
Closed-cycle variable-temperature cryostat with top sample loading, 1.5 to 300 K with a superconducting magnet running.
Dry Micro Cryostat
Compact closed-cycle cryostat with a built-in liquefier that transfers liquid helium directly to the sample holder, 5 to 500 K with < 10 mK stability.
GM Top Loader Dry Cryostat
Top-loading cryogen-free cryostat on Gifford-McMahon cooling, below 4 K to 325 K, with sample exchange without warming.
Konti Micro Cryostat Family
Compact continuous-flow cryostat with a working distance below 1 mm, 3.0 to 650 K, with modular piezo-stage upgrades and an external dry magnet up to 9 T.
Konti Spectro Cryostats
Continuous-flow cryostats for optical and non-optical setups, in top-loading exchange-gas and cold-finger variants, 3.0 to 325 K, supplied with LHe or LN2.
Konti Spectro IT
Bath cryostat with a top-loading exchange-gas variable-temperature insert, 1.2 to 325 K in continuous and single-shot modes.
Konti UHV Cryostats
Fully UHV-compatible continuous-flow cold-finger cryostats, below 3 K to 500 K, with vibration levels that allow atomic resolution.
PT Top Loader Dry Cryostat
Top-loading cryogen-free cryostat on low-vibration pulse-tube cooling, below 3 K to 325 K, for optical and non-optical experiments.
UHV 1K Bath Cryostat
1 K helium pot on an ultra-low-loss helium bath cryostat, 1.0 to 4.2 K in single-shot and continuous operation, initially conceptualized for STM, TEM and AFM measurements.
UHV JT Cryostat
Joule-Thomson stage on an ultra-low-loss helium bath cryostat: 450 mK with helium-3 or 1.0 K with helium-4, SPM / STM / AFM compatible.
UHV Split-Pair Magnet
Compact dry split-pair superconducting magnet for UHV: 3 T (upgradeable to 7 T), inner vertical bore > Ø 70 mm, side access for sample transfer and optical access, bakeable to 120 °C.
