- Electropolished 304 Stainless Steel Construction
- Electropolished cold thimble and trap interior. Provides resistance to corrosion, with superior vacuum compatibility. Reduces the effect of radiant heat on the cold surface.
- Easily removable cold thimble
DescriptionSIS cold traps are on the "cold thimble" design. The surface of the cold thimble containing liquid nitrogen at -187 °C, being exposed to the vacuum system, rapidly condenses molecules in the vapor phase. This action provides the trapping effect, and cryopumping especially for water vapor the most common condensable in vacuum systems. Pumping speed for water vapor at the trapping surface is 95 liters/sec. per sq. inch. The vapor pressure for water vapor at the cold thimble is reduced to 10-21 Torr, "theoretical," producing a low base vacuum. other gases found in vacuum processes will be sublimated or liquefied at the cold trapping surface. This effect provides a convenient trapping or collecting mechanism.
Industry standard die-cast aluminum clamp.
When vacuum pumps are first turned on they usually emit a considerable quantity of oil vapors into the air.
Mass Spectrometer filaments and heaters can be repaired and restored to a like-new condition at S.I.S.
Hermetic, Sealed, In-line Oil Mist Separator For Mechanical Vacuum Pumps.
Quick action aluminum clamp with finger closure "T" knob for positive sealing of NW flanges.
Available with Viton® or Buna O-ring, this centering ring complete with O-ring should be used when joining any two NW flanges with a quick flange clamp.
Union for connecting two different size NW flanges.
The Assimilation Traps are similar to our Coaxial Foreline Traps in that they are used between the rough vacuum pump and the diffusion (or turbo) pump to prevent backstreaming of oil into the diffusion pump.
