Ultra Low Temperature Liquid Helium Cooling Holder

The ULTST Single Tilt Ultra Low Temperature Liquid Helium Cooling Holder is used in applications to observe low temperature in-situ phase transitions and to reduce contamination due to carbon migration. It can also be used to reduce unwanted thermal effects in various analytical techniques and to facilitate EDX and EELS analyses by reducing contamination and mass loss.
