LT3M Helium Flow Cryostat

The ARS manufactured LT3M is an extended length true UHV cold head (10-11 Torr) where all of the rubber o-ring seals have been replaced with welded joints and metal seals.

The LT3M is ideal for UHV surface science where very long cold fingers are required. The LT3M has a customizable length up to 1200 mm and a rigid support tube to allow for cleaving and manipulation. The upturned feedthroughs limit the rotational footprint to just 4.8 in.
