Catalog Number - 58847-01-002

The 58847-01-002 EPP‑Porous Products Mobile Phase Filter is a polyethylene solvent pickup filter designed for HPLC reservoirs, providing high particle capacity, low flow resistance, and reliable system protection.

With a 20 µm porosity, it removes large undissolved particles, helping protect pumps, columns, and instruments. The white filter body allows easy visual detection of trapped debris, while the low resistance design ensures efficient solvent flow compared to finer filters.

Designed for 1/16 inch (1.6 mm) tubing, the unit includes PEEK-compatible connection components for secure, repeatable use. The soft, replaceable filter element supports easy maintenance and long-term operation.
