Purifier Carrier Gas Indicating, 1/4'', SS

Removes multiple impurities such as O2, H2O, CO2, CO, halogenated compounds, siloxanes, hydrocarbons (heavier than butane), sulfur-containing molecules, and ammonia from inert gases (He, Ar, N2, and H2).
Can be used with other filters to provide endpoint detection.
Contains highly sensitive visual indicators for oxygen and water contamination. The oxygen indicator signals breakthrough when the adsorbent changes from green to grey, and the moisture indicator signals breakthrough by changing from blue to brown.
Heavy-walled inner glass tube is protected by a sealed outer plastic tube to further protect against leaks.
