Oxygen Traps

Oxygen is the leading cause of column degradation. These oxygen traps use a copper-based catalyst to remove oxygen to sub-ppm levels.



This is an improved, compact indicating filter for high-efficiency oxygen removal, suitable for use with chromatography carrier gas streams. It removes oxygen to low-ppb levels, with an indicator that changes color from green to gray when adsorption capacity is depleted.

  • Inner heavy walled glass tube encased in a hard plastic tube for added safety and strength
  • Redundant three part inner seal for leak-free operation
  • Maximum fow rate of 150ml/min., maximum pressure is 100psi
  • Can be regenerated - no need to dispose
  • Approx. dimensions: 3.5 x 26cm including the fittings
  • Brass fittings (also available in stainless steel)
