In addition to the suppliers listed below:

  • SPI. Sells microscopy products (widely used for SEMs)


Not available, but may be needed.

  • Replacement "O" ring for chamber->gun vacuum tube, for the chamber-side mounting adapter. (Will this work?
    • Tim G., SEM contact, says any old Viton o-ring is suitable.
    • Ring measures 56mm Dia., 2.75mm thickness. Source
    • Plasma (talk) 23:10, 1 April 2014 (PDT)
      If they're deformed (crushed) or leave a residue when pressed onto a clean surface, then they need replacing. But really, if the vacuum holds.. let 'em be. -Gatohaus (talk)
  • Hand lens (for detecting fibers or hair on the mating surfaces) Plasma (talk) 15:21, 3 April 2014 (PDT)
  • Disposable gloves to keep organic, warm-pressed human oil off of components.
    KC Nitrile are nice, $14 per 100, maybe there's another non-latex option that's cheaper?:


Already at the space.

  • Apiezon M vacuum grease for "O" rings, to be used for vacuum seals at room temperature: ($70 for 25g). Edit: page 058 of the manual states "The use of O ring grease is not recommended on any O rings, but a small amount may be used, if necessary, on moving seals e.g. the specimen stage and apereture changer micrometers."
    • 31Mar2014 - there's a syringe of Ap. T grease in the space (~2g). It's on top of the SEM's chamber atm.
  • Cleaning alcohol Plasma (talk) 15:31, 3 April 2014 (PDT)


Frequently burned up in normal operation.

  • E-Beam Emission Filament. Hopefully we can keep that item out of the 'RoutinelyConsumed' category by warming it up gently.
