Agilent/HP Filaments can be repaired by S.I.S. We will completely clean the assembly and replace the rhenium filament wire. This is not an exchange program. Your filaments are repaired and returned to you. For a complete description of this repair service see the section on Mass Spectrometer Filament Repair and Manufacture.

Return Authorization numbers are not required.

  • SISAlloy® Filament Repairs. Filaments are repaired with Rhenium alloy (SISAlloy®) developed by SIS. SISAlloy which is an alloy of pure rhenium doped with a small concentration of Yttria. The Yttria improves the strength of the Rhenium. The electrical characteristics of SISAlloy are identical to pure rhenium, however the filament has less tendency to sag, thereby improving filament performance.


Standard Procedures for the Repair of Filaments

  • Inspected upon arrival at our facilities
  • Cleaned completely
  • Damaged or broken parts repaired or replaced
  • New filament aligned & spotwelded in place
  • Not an exchange program. Your filaments are replaced and returned to you.

For a complete description of this repair service see the section on Mass Spectrometer Filament Repair and Manufacture.

New Filaments

SIS is the world's leading manufacturer of mass spectrometer filaments Using our experience in repairing many different types of mass spectrometer filaments, Scientific Instrument Services, Inc. has redesigned several of these filaments to provide filaments that are less expensive for our customers, are more durable and have a longer life, and are easier to rebuild and clean. For a list of New Mass Spectrometer Filaments manufactured by SIS see the section entitled - New Mass Spectrometer Filaments from SIS

Shipping Instructions

Package filaments carefully when sending them in for repair

Most filament glass parts and ceramic insulators are very fragile and are easily damaged during shipment. Therefore, please package all filaments carefully to avoid damage during shipment. We recommend that you package the filaments personally. Filaments should be packaged in a box at least 6 inches square using packing peanuts or bubble pack as cushioning. We recommend shipping by UPS or Federal Express for best handling.

Ship to:
Adaptas Scientific Instrument Services
