Moisture Traps

Water which can be present in the carrier gas stream can hydrolyze common silanized supports which leads to stationary phase degradation.



This is an advanced-design gas filter for applications requiring high-efficiency moisture removal with the benefit of a depletion indicator. Up to 6 grams water is removed to low-ppb levels. The adsorbing materials are Molecular Sieve 5A and cobalt-free CoFree(TM) indicator, held in a sturdy glass tube. The gas to be purified contacts only glass, metal and the adsorbents.

  • Molecular Sieve 5A and Indicating CoFree Indicating adsorbing materials
  • Inner glass tube encased in plastic shell with threaded aluminum end caps - makes it easy to disassemble and reactivate
  • Stainless steel frits with nickel plated end fittings
  • For use below 100psig
  • Approx. dimensions: 3.2 x 26cm
