Standard Tungsten Loop Filaments, Electron Microscopy Sciences

Tungsten filments with a minimum tip radius for a coherent beam.

• Rigid attachment of the filament wire to the post
• Polished post ends
• Rebuilt many times
• Better long-term economy

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 the filament. 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.
