Spherical Stainless Steel Chambers for Ultra-High Vacuum Systems (UHVs)

MDC Standard Spherical Chambers have been designed to suit a variety of analytical studies and experiments.

These versatile chambers, available in either 16" or 12" nominal diameter, are constructed from 304L stainless steel. Both versions comprise of a wide range of access ports of varied sizes in order to accommodate connection to different experimental devices, experimental devices, analytical instruments, vacuum measurement gauge tubes, electrical and motion feedthroughs and several other accessories.

All 2-3/4" Del-Seal™ flanged ports are attached to the chamber with extra-large 1-3/4" outside diameter tubing in order to provide maximum apertures and permit the installation of bigger devices. During construction, all access ports are precision aligned with a helium-neon laser during.

Sealing and fastening hardware, including bolt sets and copper gaskets, are available under the individual size flange in the Flanges and Fittings section of the MDC catalog or on the website.
