Removes oxygen to low ppb levels from He, Ar, N2, or methane.
Indicator changes from green to gray when adsorption capacity is depleted.
Can be used with nonoxidizing gases such as He, Ar, N2, H2, or CH4.
Heavy-walled inner glass tube is protected by a sealed outer plastic tube to prevent oxygen and water infusion.
Pre-purged for fast stabilization.
160 psi (1103 kPa) maximum operating pressure.
Reduces oxygen to 100 ppb.
10 µm frits at inlet and outlet.
Optimal flow rate: < 150 mL/min.
