Catalog Number - 58835-20-005

58835-20-005 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 reliable protection of instrument components.

These filters feature a “Last Drop” flat bottom‑draw design, allowing nearly complete withdrawal of mobile phase from reservoir bottles—an essential advantage for high‑throughput workflows, long analytical sequences, and bulk solvent applications.

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