LT3B Helium Flow Cryostat

The ARS manufactured LT3B Helitran® is a true UHV cold head (10-11 Torr) where all of the rubber o-ring seals have been replaced with welded joints and metal seals.

Like all of our LT3 liquid helium flow cryostats, the LT3B is an advanced liquid helium flow cryostat utilizing many unique features, such as the matrix heat exchanger and the co-axial shield flow transfer line, to achieve unparalleled efficiency and ultra low vibration levels.

The combination of true UHV and angstrom level vibrations makes the LT3B ideal for low temperature STM applications.

For UHV surface science where very long cold fingers are required, we have the LT3M with customizable length up to 1200 mm and rigid support tube to allow for cleaving and manipulation.
