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.
