HCHST3008 Single Tilt Liquid Helium Cooling Holder

The HCHST3008 Single Tilt 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 EDS and EELS analyses by reducing contamination and mass loss.  

Key Features 

Specialized helium dewar 

• 'Vapor shielded' design requires liquid helium only and provides 1.5 hours of stable operation at base temperature with longer hold times at intermediate temperatures

Temperature operating range

• 20 to 100 Kelvin

Specimen securing mechanism

• Clamping ring screws into the specimen cradle to maintain excellent thermal contact between the specimen holder and the specimen grid

Optional beryllium specimen insert and Hexring®

• For EDS analysis

Optional electrical connections

• 2 or 4 optional electrical connections to the specimen area

System package

• Includes temperature controller, helium transfer tube, flow pump and controller, protective sleeve with pump-out fitting, pump-out tool, holder loading stand, clamping rings and clamping ring tools  

Tilt ranges and compatibility of specimen holders vary according to the TEM manufacturer, model, pole piece gap, and the presence of in-gap accessories.  Please contact your local Gatan representative for more information.
