Catalog Number - 48220-03

The 48220-03 Mobile Phase Filter is a high-capacity 316L stainless steel solvent inlet filter designed for fine particulate removal and dependable solvent delivery in HPLC systems. Manufactured for maximum durability and throughput, it effectively protects pumps, columns, and instrumentation from contamination.

The 2 µm pore size removes fine undissolved particles before they enter critical system components, supporting long column life and consistent performance.

Each filter is passivated with a 30% nitric acid treatment, improving corrosion resistance and compatibility with a wide range of mobile phases.

The integrated all‑PEEK tripod connector (3-step molded design) allows tubing to slip directly onto the fitting with no ferrules or nuts required, supporting:

• 1/16 inch (1.6 mm) tubing

• 1/8 inch (3.2 mm) tubing

Designed for direct placement in solvent reservoirs, these filters are intended for inlet (vacuum) filtration only and are not recommended for sparging.
