Agar Scientific TEM filaments are fabricated with specially developed jigs that ensure reproducibility and accuracy in production. High-ductility tungsten wire is used for minimizing strain.
Stress-relieving of all filaments is done by flashing in a vacuum at temperatures above the normal operating level, and are then checked for accuracy of centering.
Filament assemblies with alignment screws are adjusted subsequently adjusted using a light microscope to ensure that they are ready for immediate operation in the electron microscope.
Agar Scientific filaments are fabricated with specially developed jigs ensuring repeatability and precision. Full repair services are also offered by Agar.
