ZPure Glass H2O Filter

The ZPure Glass H2O Filter is for applications requiring high-efficiency moisture removal with the benefit of a depletion indicator. The adsorbing materials are molecular Sieve 5A and cobalt-free CoFree™ indicator. The CoFree indicator changes color from greenish-yellow to blue at 4-6% relative humidity to signal leaks in the system; the molecular sieve removes moisture to trace levels. The gas to be purified contacts only glass, metal and the adsorbents. 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. An internal frit at each end prevents particulate contamination.
