Automatic Twin-Jet Electropolisher The Automatic Twin-Jet Electropolisher is used to electrolytically thin TEM specimens. The twin-jet technique polishes both sides of the specimen simultaneously, achieving electron transparency within a few minutes. Electrolyte flow and polishing voltage are controlled by the Model 120 Automatic Power Control. Use the Model 220 Low Temp Container for applications at cryogenic temperatures. High-quality thin foils for TEM Electrolytic thinning of conductive materials is an effective method for quickly producing transmission electron microscopy (TEM) specimens without inducing artifacts. In the Model 110 Twin-Jet Electropolisher, twin jets polish both sides of the sample simultaneously, producing electron-transparent specimens within a few minutes. The electropolisher features easily adjustable electrolyte flow, polishing voltage, termination-detection sensitivity, and jet and specimen holder positions. Integrated operation The electropolisher consists of the electrolyte pump and motor, jet assemblies, specimen holder, fiber optic assemblies (including the light source and photocell detector), and a box that holds a glass dish for the electrolyte.
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
