Special offer - Delivery now £4.99 when ordered onlineEBS Tungsten EM filaments
Manufactured by Energy Beam Sciences (EBS) using the most recent advances in ceramic and metallurgical technologies these high quality, high stability EM filaments exceed the specifications of the original microscope manufacturers. Available for all major microscope brands.
The advantages of EBS EM tungsten filaments are:
- Minimum tip radius for a coherent beam
- Rigid attachment of filament wire to posts for increased stability
- Fully stress relieved for enhanced lifetime
- Polished post ends for better contact
- Precise dimensions for minimal alignment adjustments
- Better long term economy
Filament bases are made using high quality ceramic discs, exact size contact pins and high grade tungsten filament wire. Special jigs are used to produce the exact shape of the tungsten filament and to precisely align it with the posts before it is welded and then annealed in high vacuum to reduce stress in the filament. This guarantees optimum stability and maximum brightness with a longer lifetime and lower running costs.
There are filaments available for most current and previous makes and models of electron microscopes, including Carl Zeiss, Coxem, Hitachi, JEOL, Pemtron, Tescan and ThermoFisher (FEI).
See also our range of Kimball Physics LaB6 cathodes as an alternative to a replacement tungsten filament.
