SS Scientific are a recognised world leader in the manufacture and repair of filaments for mass spectrometers, electron ion guns, x-ray sources, ion gauges and electron scanning microscopes.

We supply filaments in a wide range of high purity wire or ribbon, straight or coiled with either Thoria or Yttria coating.

We also offer a pre-condition service once the filament assembly is completed which helps to reduce impurities and a rise in pressure when emission is switched on.

Our wealth of experience in the manufacturing techniques used to produce our filaments is our guarantee of the highest quality.

We use state of the art equipment throughout our processes of cleaning, electro polish with laminar flow for final assembly.

We can supply one off prototype filament assemblies from your specifications and drawings, manufacturing in quantities as required.

At all times our design and production teams work in partnership with you to deliver a filament that is right for your application.
