The Model 2560 Vacuum Transfer Tomography Holder is a single-axis holder capable of tilting ±70° and is designed for room-temperature applications. The holder provides up to 1 mm field of view.

For specimen protection during transfer to the TEM, an advanced mechanism retracts the specimen into the body of the holder, which in turn seals and isolates the specimen from the surrounding atmosphere. The holder is ideal for sensitive specimens that can be altered by environmental conditions; the specimen can be transferred in the presence of vacuum or an inert gas environment.

Loading TEM specimens in vacuum or an inert atmosphere requires the use of a glove box; the holder is designed specifically for use with a glove box to ensure specimen protection and successful transfer to the TEM.

To load a specimen, place the holder on the loading stand and open the specimen spring clamp with the clamp tool. Once the glove box is pumped, use the forceps to place the specimen in the holder. Retract the specimen within the holder; the spring clamp secures the specimen automatically without the need of the clamp tool. The specimen is now in a vacuum/an inert environment and ready for transfer to the TEM.

The holder tip accepts a 3 mm diameter TEM specimen or grid, which is secured with a spring clamp. When engaged, the clamp provides a secure force on the edge of the specimen and maximizes specimen visibility, even at high-tilt angles.

Included with the holder are a holder loading stand, a Model 9010 Vacuum Storage Container, a loading stand, forceps, and a specimen clamp tool.

• Advanced mechanism retracts the specimen into the body of the holder, which seals and isolates the specimen from the surrounding atmosphere
• Ideal for sensitive specimens that can be altered by environmental conditions
• Can be used to gather tomographic data in TEMs with a pole-piece gap > 5 mm
• Is compatible with the microscope’s touch alarm, which stops goniometer movement in the event that a pole touch occurs

Available for both JEOL and Thermo Fisher Scientific microscopes.
