Product Description:

This is a compact indicating purifier 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. The adsporbent forms copper oxide in the presence of oxygen; no gas is generated. The ZPure Glass O2 Filter is recommended as a downstream indicator for high-capacity purifiers such as the ZPure Dual or the stainless steel ZPure O2 Filter. It can be used with non-oxidizing gases such as He, Ar, N2, H2 or CH4.  Dual Seal Design: In this design the heavy-walled inner glass tube is protected by a sealed outer plastic tube. This design provides extra protection if the glass tube were to fail, the gas system is still fully protected against leaks.  *This item ships as a hazardous small quantity exception.
