    http://site-overview.com/stats/kimballphysics.com
    Kimball Physics is a high-tech manufacturer of scientific instruments in ultra-high-vacuum electron and ion optics. KP also manufactures unique, versatile, compact, multi-port vacuum chambers. Kimball Physics Multi-CFTM UHV vacuum chambers and fittings are a unique and innovative assembly of vacuum hardware providing users with distinct benefits over conventional Conflat components. They are particularly advantageous where there are spatial constraints and where a high density of experimental apparatus is required. Ultra High Vacuum performance is improved with highly polished surfaces, contoured interiors and minimal welds. In addition, the modular Multi-CFTM system incorporates built-in internal and external mounting capabilities and apparatus, saving time and eliminating custom design and machining for experimental set-ups. Standard accessory elements include, Groove Grabbers, eV PartsTM and External Mounting Brackets, which are all designed to attach and fit together so that custom experimental set-ups can be made easily, accurately and reproducibly. The combination of benefits generally results in improved experimental utility and versatility, vacuum performance and often a lower overall cost.
