Catalog Number - 58846-E-07

58846-E-07 ARE‑Applied Research Mobile Phase Inlet Filter is a biocompatible, all‑PTFE economy filtration solution designed for HPLC, UHPLC, and LC‑MS mobile phase delivery systems, delivering high throughput, excellent chemical compatibility, and maximum solvent usage.

This filter features a “Last Drop” flat bottom‑draw design, enabling nearly complete withdrawal of solvent from reservoir bottles—reducing waste and helping maintain uninterrupted analytical operation.

Constructed entirely from PTFE, this filter offers broad solvent compatibility, low extractables, and suitability for sensitive applications, while providing a budget‑friendly alternative to more complex inlet filter assemblies.
