We are constantly adding insulators for Dupont and other manufacturer's instrument systems. The following alumina insulators are currently available for the Dupont/CEC Mass Spectrometers. If other sizes and/or types are required, please write us, 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.
