Multi-CF Comparison Chart & Prices

Multi-CF chambers various sizes: UHV Vacuum Fittings and multi-port, miniature ultra high vacuum chambers.

  • The table below lists most of the standard Multi-CF™ Vacuum Chamber and Fittings part types. 2.75"CF ports and larger have Grabber Grooves for mounting apparatus using Groove Grabbers. See Internal and External Mounting Systems.  The exception to this are the Mounting Flanges where the Grabber Grooves are optional.
  • Additional custom designed parts are possible; contact Kimball Physics Engineering.
  • All Kimball Physics Multi-CF™ flange fittings are compatible with industry-standard ConFlat* flanges.
