Retipped Filaments
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.
