简介

该真空传输断层扫描样品架专为敏感样品设计，可在转移至透射电子显微镜（TEM）过程中保护样品免受环境影响。通过将样品缩回并密封在主体中，隔绝周围大气。适用于需要在真空或惰性气体环境中转移的样品，接受3毫米直径的样品或网格，可倾斜±70°，适用于具有5毫米以上极靴间隙的TEM进行层析成像。同时兼容Thermo Fisher Scientific和JEOL品牌的TEM。样品加载简便，支持在手套箱内操作以确保样品保护。具备触碰保护功能，与TEM的触碰报警系统兼容。

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.
