Comparison Chart and Prices

The table below lists most of Kimball Physics standard Multi-CF™ Vacuum Chamber and Fittings.

  • All Kimball Physics Multi-CF™ fittings are compatible with industry-standard Conflat* flanges.
  • Most part types 2.75"CF ports and larger have Grabber-Grooves™ for mounting experimental apparatus using Groove-Grabbers™. Exceptions are Mounting Flanges where the Grabber-Grooves™ are optional.
  • Custom designs are welcomed. If you can't find a chamber or fitting that meets your requirements, contact us.
