Catalog Number - 58847-20

The 58847-20 EPP‑Porous Products Mobile Phase Filter is a made‑to‑order polyethylene solvent pickup filter designed for direct use in HPLC reservoirs, offering high particulate capacity and efficient solvent flow.

With a 20 µm pore size, it removes large undissolved particles, protecting pumps, columns, and instruments while maintaining lower flow resistance than 2 µm or 10 µm filters. The white filter element allows quick visual detection of trapped debris, helping determine when replacement is needed.

The all‑PEEK tripod (3‑step molded) connector enables direct tubing connection without ferrules or nuts, supporting both:

• 1/16 inch (1.6 mm) tubing

• 1/8 inch (3.2 mm) tubing

Designed for inlet (vacuum) filtration only, this unit is not intended for sparging applications.
