eV Parts are a group of 350+ standardized parts that save time and money in construction of all types of surface physics and high vacuum apparatus. eV Parts are made of high quality materials and designed for maximum flexibility. Parts are manufactured to standard dimensions with high tolerances and may be used to modify or add to existing commercial high vacuum apparatus with little effort. Ordinary hand tools are the only additional tools needed to use eV Parts. For permanent applications, a laboratory spot-welder may be used. eV Parts come in standard packages where QTY/PKG varies by product type. Quantity discounts available for multiple packages in the eV Parts series.
High-Quality Vacuum Materials
eV Parts are manufactured from the highest quality materials available and can easily withstand 500°C bakeouts. Standard parts are made of chemically cleaned 304 stainless steel and insulators are made of best grade 98/99% pure vitreous alumina. Refractory metal fasteners and springs are available for non-magnetic structures. Other materials including tantalum or gold plated stainless are available on request.
eV Parts may be used to build rigid, self-supporting, and dimensionally stable assemblies. eV Parts are self-aligning by virtue of their mounting holes and remain locked in place even over extended bakeouts. Parts are assembled on centerless-ground ceramic rods and secured using any of a variety of fasteners: lock rings, screw clamps, strap nuts, friction wirenuts, and ordinary machine screws. Parts fit reliably and make the accurate alignment of lenses, slits, and apertures straight-forward. Assemblies may be disassembled quickly for modification, salvage, or cleaning. Permanent assemblies can be spot-welded.
