Cleans specimens immediately before they are inserted into the electron microscope; removes existing carbonaceous debris from the specimen and prevents contamination from occurring during imaging and analysis. The Plasma Cleaner (shown with the Model 9020 Vacuum Pumping Station) automatically and quickly removes organic contamination (hydrocarbon) from electron microscopy specimens and specimen holders. Contamination typically comes from several sources: inadvertent touching of specimens or specimen holders, back-streaming of oil from an oil diffusion pumped ion milling system, electron microscope column contamination, and adhesives or solvents used in the preparation process. Even when great care is taken to clean the specimen, standard cleaning methods are often not 100% successful. Plasma cleaning removes existing carbonaceous debris from the specimen and prevents contamination from occurring during imaging and analysis. A low-energy, inductively coupled, high-frequency plasma effectively cleans a specimen surface without changing its elemental composition or structural characteristics. Highly contaminated specimens can be cleaned in 2 minutes or less. The plasma cleaner removes contamination from a wide variety of materials prepared by a variety of techniques. The specimen holder is inserted through a single port into the plasma chamber. The port contains a vacuum-sealing surface compatible with the specimen holder’s O-ring. Ports are easily interchangeable in as little as 10 seconds. For cleaning specimens containing significant amounts of carbon or specimens mounted onto carbon support grids, shielded specimen holder ports are available that optimize the cleaning action of the plasma. The Plasma Cleaner readily accepts side-entry specimen holders for all commercial TEMs and STEMs and can accept bulk specimens for cleaning before SEM or surface analysis. The Plasma Cleaner includes the customer's choice of specimen holder port, pumping port assembly, and blank plug assembly. Ports are available for electron microscopes manufactured by: - Thermo Fisher Scientific/FEI Company/Philips Electron Optics - Hitachi High Technologies America Inc. - JEOL Ltd. - Carl Zeiss Microscopy - Topcon Corp.
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
