Cryo transfer and tomography of thin-film frozen-hydrated/vitrified specimens for low-dose imaging and analysis. Ideal for specimens that require liquid nitrogen cooling for transfer to a transmission electron microscope for imaging and analysis. The Cryo Transfer Tomography Holder is an advanced, single-tilt holder that provides cryogenic specimen cooling and transfer 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. The innovative design of the specimen tip makes loading and unloading of the specimen very easy. The holder accepts a 3 mm diameter TEM specimen grid that is secured by the holder’s one-piece, integrated specimen clamp. The specimen holder tip retracts inside an actively cooled cryo shield located within the end of the holder. The specimen clamp automatically closes when the holder tip is retracted. The Cryo Transfer Tomography Holder rapidly reaches a working temperature of -175 °C or better. Hold times in excess of 4 hours are readily obtained with the 200 ml capacity dewar. A zeolite absorption medium enhances dewar vacuum. The cryo workstation facilitates the handling of the specimen and its loading into the holder. The modular design of cryo workstation allows you to reposition the reservoirs to enhance ease-of-use for both right- and left-handed operation. The temperature controller connects directly to the specimen holder dewar and displays the holder tip temperature. The holder includes: a Model 9010 Vacuum Storage Container, an anti-boiling tool, a specimen loading tool, and Viton tubing. The cryo workstation and the temperature controller are purchased separately. For evacuating the holder during zeolite regeneration, Fischione Instruments recommends the Model 9030 Turbo Pumping Station. Prior to freezing thin films, TEM carbon support grids should be cleaned to remove hydrocarbons and to make the grids’ surface hydrophilic. Fischione Instruments recommends that you clean the support grids with the Model 1020 Plasma Cleaner or Model 1070 NanoClean. The Model 2550 Cryo Transfer Tomography Holder is available for both JEOL and Thermo Fisher Scientific microscopes.
Includes all the components required to produce high quality cross-section specimens for transmission electron microscopy. Widely used cross-section specimens include semiconductor devices (which often have multiple layers and, thus, multiple interfaces), specimens with thin film layers, and composite materials. For the study of interfaces by transmission electron microscopy, it is critical to align the interface of interest parallel to the incident electron beam. One method for preparing such samples is to fabricate cross-section specimens. - Stacks and holds cross-section specimens - Aligns areas and interface of interest - Produces consistent glue layer thickness - Resulting stacks are readily cut by the Model 170 Ultrasonic Disk Cutter - Fabricate self-supported 3 mm diameter disk specimens

Specimen Grinder. Mechanically prethins specimens for transmission electron microscopy. Produces uniform thickness specimens with parallel sides. Greatly reduces the time spent during the final preparation process of ion beam milling. For transmission electron microscopy, the quality of the initial disk determines the quality of the final specimen. The disk can be mechanically ground using the Model 160 Specimen Grinder to a precisely controlled thickness. Use the Model 200 Dimpling Grinder for final thinning. - Accurate and dependable - Precisely controlled - Specimens up to 18 mm diameter - No additional force needed - Large diameter provides excellent stability - Platen transferable to the Model 200 Dimpling Grinder

Ultra-Narrow Gap Tomography Holder. A holder capable of tilting up to 90° while providing a maximized field of view for transmission electron microscopy. The Model 2030 Ultra-Narrow Gap Tomography Holder is capable of tilting up to 90° while providing a maximized field of view. The holder is suitable for ultra-narrow gap (< 3 mm) pole-piece geometries. The Ultra-Narrow Gap Tomography Holder accepts a 1.5 mm square or round TEM specimen or grid into a cartridge, securing it with a single clamp. Items included are a specimen loading stand, a Model 9010 Vacuum Storage Container, a loading fixture, a clamp tightening tool, copper grids, tweezers, and a spare parts kit. The holder: - Specimen loading station allows easy positioning and clamping of the specimen into the cartridge - Has a streamlined specimen clamping mechanism eliminates the shadowing associated with most holders at high-tilt angles - Has a retractable clamp that evenly distributes force on the specimen - Accommodates specimen thicknesses up to 100 μm - Is compatible with the TEM’s touch alarm, which stops goniometer movement in the event that a pole touch occurs The holder is available for both JEOL and Thermo Fisher Scientific microscopes.

Produces high quality disk specimens from thin metal foils. A precision ground punch and die plate eliminate specimen stress and distortion. An ideal accessory to the Model 110 Automatic Twin-Jet Electropolisher. The specimen punch is available with a standard base or with a wide base, which provides extra stability when producing thin foils. A precision ground punch and die plate eliminate specimen stress and distortion of the disk specimen. A spring-loaded return plunger keeps the disk specimen on the die plate surface for convenient handling. Available in standard sizes of 1 mm, 2.3 mm, and 3.0 mm; other sizes available upon request
