Cryo transfer and tomography of thin-film frozen-hydrated/vitrified specimens for low dose imaging and analysis
Key Features
Liquid nitrogen cooling - The Cryo Transfer Tomography Holder is an advanced single-tilt holder that provides cryogenic specimen cooling with an extended field of view at high-tilt angles up to 80°. Tomographic data can be acquired in TEMs with pole-piece gaps of approximately 5 mm. Included with the Model 2550 Cryo Transfer Tomography Holder is a Cryo Work Station, a Temperature Controller, a Model 9010 Vacuum Storage Container, and a specimen tool
Simple specimen loading and transfer - The modular design of Cryo Work Station’s grid box allows you to re-position the reservoirs to enhance ease-of-use for both right, and left, handed operation. The thin profile of the clamp maximises specimen visibility, even at high-tilt angles and the specimen holder tip retracts inside an actively cooled cryo shield located within the holder which prevents any atmospheric water from condensing on the specimen during transfer to or from the microscope
Rapid cool down, extended hold time - The Cryo Transfer Tomography Holder rapidly reaches a working temperature of less than -175 °C in either the Cryo Work Station or a TEM. Hold times in excess of 4 hours are readily obtained with the 200 ml dewar capacity. A zeolite absorption medium enhances dewar vacuum. The Temperature Controller connects directly to the specimen holder dewar and displays the holder tip temperature
