915 Double Tilt Liquid Nitrogen Cryo Transfer Holder

The 915 Double Tilt Liquid Nitrogen Cryo Transfer Holder is designed for low temperature transfer and subsequent tomographic recording of electron beam sensitive, frozen hydrated specimens in the TEM.

Key Features

ToggleTilt™ beta drive mechanism

• Provides robust operation with no mechanical binding of the specimen cradle at tilt limits 

Analytical Design

• Specimen cradle, Hexring® and Anti-twist washer are made of beryllium

Low drift design 

• High mechanical stability by conduction cooling from well-insulated, bubble-free dewar

Precise temperature measurement

• Temperature of the holder is monitored by a calibrated silicon diode which provides a sensitive, linear temperature response

• The conductor rod connecting the specimen holder tip to the liquid nitrogen dewar contains an electric heater to change the specimen temperature

Frost-free specimen transfer

• Light weight cryo workstation provides low temperature specimen loading to protect the frozen hydrated grid

• One piece cryo shield encapsulates the frozen hydrated grid providing protection against damage caused by warming and frost formation during transfer from the workstation to the electron microscope

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.
