Catalog Number - 48220-05

The 48220-05 Mobile Phase Filter is a durable 316L stainless steel solvent inlet filter designed for high-capacity particulate removal and efficient solvent flow in HPLC systems. Built for excellent throughput and system protection, it helps prevent contaminants from reaching pumps, columns, and instrumentation.

The 10 µm pore size removes larger undissolved particles while maintaining low flow resistance, supporting consistent solvent uptake and improved vacuum efficiency compared to finer filters.

Each unit is passivated with a 30% nitric acid treatment, enhancing corrosion resistance and ensuring compatibility with a wide range of HPLC solvents.

Designed for 1/8 inch tubing, each filter includes PEEK connection components for secure, reliable low-pressure connections.
