Inline LN2 Cooled Traps (Single Fill Tube)

Works in vacuum systems containing solvents, water vapor, or organic vapors.

  • Traps volatile materials before they can enter the mechanical pump to ruin the foreline pressure and contaminate the oil
  • Traps all oil vapors before they can enter the chamber from the mechanical pump
  • Acts as a pump, producing lower base pressures and faster pump down
  • Two-piece split-housing body enables quick removal of the reservoir for cleaning without disassembling the system

NOTES: 4" traps holds 0.75 liter LN2 and 6" traps holds 1.6 liters LN2. Under standard conditions, 4" diameter traps can run a maximum of 5 hours before needing a refill; 6" diameter traps can run a maximum of 8 hours before requiring more liquid nitrogen.
