Catalog Number - 48220-02

The 48220-02 Mobile Phase Filter is a robust 316L stainless steel solvent inlet filter designed for high-efficiency particulate removal and consistent solvent flow in HPLC systems. Built for high capacity and excellent throughput, it helps protect pumps, columns, and instrumentation from contamination.

The 2 µm pore size provides fine filtration of undissolved particles, delivering enhanced protection compared to higher micron inlet filters.

Constructed from 316L stainless steel and passivated with 30% nitric acid, this filter offers superior corrosion resistance and durability across a wide range of solvents.

Designed for 1/8 inch tubing, each unit includes PEEK connection components for secure, low-pressure compatibility.
