SPI Supplies Brand Rebuilt Electron Microscope Filament for all Zeiss Models
Rebuilt Filament for Zeiss Camscan/Tescan
SPI is also able to save our customer large amounts of money by retipping used filaments. You, the customer, supply the bases and container and we will return them, all retipped, ready to use, typically for cost savings of roughly 50% (or more) off the price for new filaments.
Therefore the full range of electron microscope filaments is available "retipped" as well as new. Despite the fact that there are numerous different electron microscope models, and different geometries to the filament bases, we have organized the selection process to make it easy to determine the cost of retipping any particular style of filament.
Some instruments are reported to run even better with a "pointed" filament (e.g. pointed loop) because of a greater coherency of the beam, leading to better contrast and resolution.
All SPI retipped filaments are constructed with a special-alloy tungsten wire, 3% rhenium doped and are formed in high-precision fixtures. These filaments are fully annealed, precision aligned and strain-free. Microscopic inspection assures consistent quality and performance. New Filaments, both new and retipped, come 10 to a box and are easy to see and retrieve from the special protective packaging. However, before retipping, the base is sandblasted and other wise cleaned and returned almost to its clean and pristine condition as when it was new. Filaments shipped in special container at extra cost if one is not supplied by customer.
Some of our customers have accumulated large quantities of filaments bases (e.g. burned out filaments). We say "there is gold in those bases". Return ten boxes and you will received one free box retipped and returned to you freight prepaid any where in the world. Just be sure that each box worth of filaments is returned in its "box", and not just loose.
Note: We reserve the right to limit this offer to keep our over stock in balance. Be sure to contact SPI first, before returning anything. Be sure to get a valid Return Authorization number.
