SPI Supplies Brand Rebuilt Electron Microscope Filament for JEOL GC Models, each
Rebuilt Filament for JEOL JSM GC
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 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.
