• An 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

• Optimized for transferring specimens under vacuum or in the presence of inert gas

• Provides a large field of view in transmission electron microscopes (TEMs) possessing a ST or wider gap pole piece

• Capable of tilting to ��70��; can be used for tomography in microscopes with pole-piece gaps > 5 mm

• Accepts 3 mm specimens or specimen grids

• Available for both Thermo Fisher Scientific and JEOL TEMs

Vacuum transfer for TEMs

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 a large field of view in TEMs possessing a ST or wider gap pole piece.

Specimen protection from atmosphere

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 Vacuum Transfer Tomography Holder is designed specifically for use with a glove box to ensure specimen protection and successful transfer to the TEM.

Simple specimen loading and transfer

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 tweezers 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.

Accepts 3 mm specimen or grid

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.

Gather tomographic data

The Vacuum Transfer Tomography Holder tilts �� 70�� and can be used to gather tomographic data in TEMs with a pole-piece gap > 5 mm.

Touch protection

Fischione’s advanced tomography holders are compatible with the TEM’s touch-alarm that stops goniometer movement in the event that a pole touch occurs. Always be aware of the TEM’s pole-piece configuration and follow the microscope manufacturer’s recommendation for operating the goniometer at high-tilt angles.
