Ceramic Insulators for Finnigan MAT

Ceramic and Sapphire Insulators

We are constantly adding insulators for Finnigan MAT and other manufacturer's instrument systems. The following alumina insulators are currently available for the Finnigan MAT instruments. If other sizes and/or types are required, please write us or give us a call or send an old or damaged unit and we will see if we can supply it. All listed insulators are constructed from a high quality aluminum oxide ceramic unless otherwise noted. Additional ceramic and sapphire insulators are listed in the ceramics section of these pages.

All dimensions in inches, tolerances +/- 0.002 inches.
