Product Description

Agar Scientific tungsten filaments are made with specially designed jigs which ensure accuracy and reproducibility in production. High-ductility tungsten wire is used to minimise strain. All filaments are stress relieved by flashing in a vacuum at temperatures above the normal operating level and are then checked for accuracy of centring.

Filament assemblies having alignment screws are subsequently adjusted using a light microscope to ensure that they are ready for immediate operation in the electron microscope.
