The Finnigan MAT 4000 filaments have been redesigned to provide a filament that has fewer parts, is easier to rebuild, and is less costly to manufacture than the original filament.
This new filament is constructed from a single piece of high purity alumina ceramic with the filament posts and silver filament leads permanently attached. The result is a one piece filament costing half the price of the original Finnigan filament.
SIS repairs all Finnigan MAT filaments, see section on Finnigan Filament Repair.
