Catalog Number - 58835-20-002

58835-20-002 ARE‑Applied Research Mobile Phase Inlet Filters are high‑capacity, economy solvent filtration devices engineered for HPLC, UHPLC, and LC‑MS mobile phase delivery systems, delivering maximum solvent recovery, ultra‑low flow restriction, and dependable protection of critical instrument components.

These filters feature a “Last Drop” flat bottom‑draw design, enabling nearly complete withdrawal of solvent from reservoir bottles—an essential advantage for high‑throughput workflows, bulk solvent usage, and long unattended runs.

Each filter incorporates a 10 µm stainless steel filter element combined with PEEK / PTFE structural components, offering exceptional durability, chemical resistance, and long service life in demanding analytical environments.
