Featuring an overmolded or welded polypropylene housing, a 50-mm process filter is offered for use in various applications. Engineered for high-performance venting or liquid applications, the filter has a standard 0.2-µm PTFE membrane. Liquid applications can include aqueous solutions, high-performance liquid and gas chromatography solvents, cell-culture media, and protein solutions. Though the welded filter achieves burst pressures of only 50 psi versus the 100-psi burst pressure capability of the overmolded version, the welded filter offers a lower profile and cost-efficient design. The housing comes standard with 1⁄4-, 3⁄8-, or 1⁄2-in barbed ports. Custom port configurations and membrane options are available. Custom inlet and outlet connection options are also offered.
