Filaments for Philips (S loop)

Box of 10

SPI Supplies is pleased to offer filaments, brand new, usually the original product from the manufacturer but still at attractive prices. However, if the new filaments carry the SPI Supplies name instead of the name of the original manufacturer, you can be sure that SPI guarantees equivalence in performance or else a full refund is immediately made upon the return of the unused box. In all the years that we have been offering new filaments, including some under the SPI name, we have almost never been asked to take back filaments because the performance of the filaments was below the customer's expectations.

We are often times asked about "expected filament lifetimes" and that is a hard question to answer. Quite a bit is already known as to the factors that influence filament lifetimes; be sure you are aware of how you can get the maximum lifetime out of your tungsten filaments, be they new or retipped. In addition, the quality of the cleaning of the wehnelt cap when changing a filament can be, at least in some instruments, the single most critical factor affecting filament life times.
