Kimball Physics UHV Multi-CF™ Fittings is a unique line of ultra high vacuum fittings
including modular chambers, complex instrument
housings, apparatus mounts and flanges. These components are compatible
with standard ConFlat* (CF) flanges and provide maximum internal
volume for a given CF size. Multiple ports provide
exceptional internal access. The components are made of 316
stainless steel, 304 stainless steel, or titanium, and are serial numbered for
traceability. All fittings are UHV bakeable to 450oC and
have mirror-like, UHV-clean interior-surface finishes.
In addition to having a
variety of unique complex shapes, the Multi-CF™ Fitting line uses a flexible method of
mounting apparatus inside of vacuum. Called the
Groove–Grabber / Grabber–Groove system, this technology permits easy
mounting of almost any kind of equipment or device, from the inside
diameter of any prepared flange or port.
The table
below presents the basic part types. Several sizes are
available for most types. Sizing is based on the largest CF port of
the fitting.
