SPI Supplies Brand Rebuilt Scanning Electron Microscope Filament for All FEI/Philips Models,AR-Loop
Rebuilt Filament for FEI and FEI-Philips (All Models) (AR LOOP)
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. However, before retipping, the base is sandblasted and otherwise cleaned and returned almost to its clean and pristine condition as when it was new. Filaments shipped in a special container at extra cost if one is not supplied by the customer.
