Catalog Number - 58835-E-10-005

58835-E-10-005 ARE‑Applied Research Mobile Phase Inlet Filters are economy, high‑capacity solvent filtration devices engineered for HPLC, UHPLC, and LC‑MS mobile phase delivery systems, providing maximum solvent recovery, high throughput, and reliable protection of critical instrument components.

These filters combine a 5 µm stainless steel filter element with PTFE structural components, delivering robust durability and excellent chemical compatibility in a simplified, cost‑effective configuration.

The “Last Drop” flat bottom‑draw design enables nearly complete solvent removal from reservoir bottles, helping reduce waste and support uninterrupted chromatographic operation during long or high‑volume runs.
