Catalog Number - 48220-01

The 48220-01 Mobile Phase Filter is a durable 316L stainless steel solvent inlet filter designed for high-efficiency particulate removal and long-term use in HPLC systems. Engineered for high filtration capacity and excellent solvent throughput, this filter protects pumps, columns, and instrumentation from particulate contamination.

The 2 µm porosity effectively removes fine undissolved particles, offering enhanced system protection compared to higher micron inlet filters.

Constructed from passivated 316L stainless steel (30% nitric acid treated), this filter provides improved corrosion resistance and chemical durability across a wide range of solvents.

Designed for use with 1/16 inch tubing, the unit includes PEEK connection components for secure, low-pressure fittings.
