High quality replacement tungsten filaments for Cambridge, LEO, Zeiss, AEI, FEI, JEOL, Siemens, Camscan, ISI electron and TESCAN electron microscopes. These high quality tungsten filaments are made with specially designed jigs which ensure accuracy and reproducibility in production. Sold in a box of 10.
These high quality 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 relieved of any additonal stress 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.
