Palladium Tube - OD 5mm ID 4.4mm L 1000mm

Details

SKU: 1000080550 Product Code: PD00-TB-000250
Palladium Tube combines excellent corrosion resistance, high hydrogen permeability, and catalytic performance in a hollow form ideal for gas transport and reactive processing environments. Industries such as chemical engineering, renewable energy, and analytical instrumentation use palladium tubes for hydrogen purification systems, catalytic membrane reactors, and protective gas delivery conduits. Specific applications include selective hydrogen separation, catalytic reforming processes, and laboratory-scale gas flow control. In research, they are central to studies on hydrogen transport mechanisms, membrane reactor optimization, and long-term corrosion resistance. Their ability to integrate structural stability with functional catalytic and separation properties ensures a critical role in advanced technological systems.
