DRY ICE DYAD
The DRY ICE DYAD is a closed-cycle system capable of cooling to 1.4K whilst providing excellent optical access and ultra-low vibration. The sample unit is held separately from the cold head and the main body of the cryostat on an optical table. The two are connected only by a soft thermal link to reduce vibration to a minimum.
The sample space environment can be switched between a top-loading exchange gas module and a vacuum module within a couple of hours, making it a flexible solution for multiple applications in busy labs.
Customisation of the wiring and the addition of magnetic fields, nanopositioners and low-temperature objectives are available.
