ZPure Glass Traps/PurifiersZPure Glass Indicating O 2 TrapThe ZPure Glass Indicating O 2 Trap is an improved, compact indicating filter for highefficiencyoxygen removal, suitable for use with chroma<strong>to</strong>graphy carrier gas streams. Itremoves oxygen <strong>to</strong> low-ppb levels, with an indica<strong>to</strong>r that changes color from green <strong>to</strong> graywhen adsorption capacity is depleted. The adsorbent forms copper oxide in the presence ofoxygen; no gas is generated.ZPure Glass Indicating O 2TrapThe ZPure Glass Indicating Oxygen Trap is recommended as a downstream indica<strong>to</strong>r forhigh-capacity traps such as the ZPure Dual or ZPure O 2 . It can be used with non-oxidizinggases such as He, Ar, N 2 , H 2 or CH 4 . Dual seal design (see box below). Gas lines areprotected from dust by 10μ frits at both ends of the filter. Maximum pressure is 6.8 bar (100psig). Approximate dimensions are 3.5 cm x 26 cm including fittings. Available with either 1/8”or 1/4” brass or stainless steel compression fittings.Description Brass StainlessZPure Glass Indicating Oxygen Trap, 1/8” fittings 202236-B 202236-SSZPure Glass Indicating Oxygen Trap, 1/4” fittings 202237-B 202237-SSReconditioned,1/8” fittings 202236R-B 202236R-SSReconditioned 1/4” fittings 202237R-B 202237R-SSZPure Glass H 2 O/HC PurifierThe inner glass tube contains activated carbon, Co-Free moisture indica<strong>to</strong>r and molecularsieve.
