产品描述
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
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.
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.
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.
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.
The Vacuum Transfer Tomography Holder tilts ± 70° and can be used to gather tomographic data in TEMs with a pole-piece gap > 5 mm.
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.
在转移到透射电子显微镜的过程中提供样品保护。
一个先进的机构将样本缩回到支架的主体中，从而将样本与周围的大气密封并隔离
非常适合可被环境条件改变的敏感样品
优化用于在真空或存在惰性气体的情况下转移试样
在具有ST或更宽间隙极片的透射电子显微镜（TEM）中提供大视场
可倾斜至±70°；可用于极片间隙>5 mm的显微镜中的断层扫描
接受3 mm试样或试样网格
适用于赛默飞世尔科技公司和JEOL TEM
TEM的真空转移
2560型真空转移层析成像支架是一种能够倾斜±70°的单轴支架，专为室温应用而设计。支架在具有ST或更宽间隙极片的TEM中提供了大的视场。
样品大气保护
为了在转移到TEM的过程中保护样本，一个先进的机构将样本缩回到支架的主体中，从而将样本与周围的大气密封和隔离。支架是敏感样品的理想选择，这些样品可能会因环境条件而改变；样品可以在真空或惰性气体环境中转移。
在真空或惰性气氛中装载TEM样品需要使用手套箱；真空转移层析成像支架专门设计用于手套箱，以确保样品得到保护并成功转移到TEM。
简单的样品装载和转移
要加载试样，请将支架放在加载台上，然后用夹具打开试样弹簧夹。抽完手套箱后，用镊子将样本放入支架中。将试样收回支架内；弹簧夹自动固定样本，而不需要夹具。样品现在处于真空/惰性环境中，并准备转移到TEM。
接受3 mm样本或网格
支架尖端接受直径为3 mm的TEM样本或网格，该样本或网格用弹簧夹固定。当接合时，夹具在试样边缘提供一个安全的力，并最大限度地提高试样的可见性，即使在高倾斜角度下也是如此。
收集断层图像数据
真空转移层析成像支架倾斜±70°，可用于收集极片间隙>5 mm的TEM层析成像数据。
触摸保护
Fischione的先进断层摄影支架与TEM的触摸报警器兼容，该报警器在发生触杆时会停止测角仪的移动。始终注意TEM的极片配置，并遵循显微镜制造商的建议，在高倾角下操作角度计。
