Kimball Physics UHV (Ultra-High Vacuum) Vacuum Chambers
Kimball Physics UHV (Ultra-High Vacuum) Vacuum Chambers are precise, modular, multiport fittings and housings that utilize integrated ConFlatTM (CF) sealing surfaces at each port.
Kimball Physics Multi-CFTM UHV fittings are designed as both instrument housings and as vacuum chambers, with the specific design intent to:
- Conveniently support a diversity of internal apparatus
- Permit complex port arrangements
- Maximize interior functional volume while remaining compact to minimize their external footprint
- Provide convenient internal access
- Improve pumping efficiency
- Follow a modular dimensioning system
- Cluster together in close proximity
Most of the chambers include internal mounting channels “Grabber Grooves” along the internal bore of their ports (2.75″ or greater) to enable secure mounting of internal apparatus. A circumferential array of double density threaded holes is typically associated with the flange port of each CF sealing surface to enable chambers to be rotated in smaller angular increments while also providing redundancy.
Vacuum Chamber Configurations
The vacuum chamber design is initially based on an internal and external spherical geometry. Many configurations are available, including our most common designs of Spherical Cubes, Spherical Squares, and Spherical Octagons. Other versatile designs are also available for your application: Spherical Decagon, Spherical Dodecagon, Spherical Hexadecagon, Spherical Hexagon, Spherical Pentagon, and Spherical Triangle.
Vacuum Chamber Sizes
The chamber sizes range from miniature and sub-miniature designs (with primary CF ports of 0.95″, 1.33″ and 2.75″) up to systems with 4.50″, 6.00″, 8.00″ and 10.00″ primary ports.
The chambers are typically fabricated from a single piece or monolith of 316L Stainless Steel. Custom designs are also available in Titanium for reduced weight, low magnetic permeability, and minimized outgassing of hydrogen for Extreme High Vacuum (XHV) applications.
