Catalog Number - 48220-08-005

The 48220-08-005 Mobile Phase Filters are high-capacity 316L stainless steel solvent inlet filters engineered for efficient large-particle removal and consistent solvent delivery in HPLC systems. Designed for durability and high throughput, they help protect pumps, columns, and instrumentation from contamination.

The 20 µm pore size removes larger undissolved particles while maintaining very low flow resistance, improving solvent uptake and reducing vacuum strain compared to finer filters.

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

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