arrow11*Rebuilding Services

The base assembly of all of our new filaments are guaranteed to be rebuildable for the lifetime of the electron beam instrument. All of our filaments, new or rebuilt, are inspected for consistent quality and performance before being shipped to you. Return the base and we will rebuild it to meet its original specifications.

Filament Rebuilding Services Include: Reconditioning of the base; cleaning and/or replacement of necessary parts; Installment of new standard loop or special filament tip; Pre-centering; Vacuum normalizing; and Microscopic inspection.
