Catalog Number - 58835-E-10-002

58835-E-10-002 ARE‑Applied Research Mobile Phase Inlet Filters are economy, high‑capacity solvent filtration devices designed for HPLC, UHPLC, and LC‑MS mobile phase delivery systems, offering maximum solvent recovery, high throughput, and reliable protection of system components.

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

The “Last Drop” flat bottom‑draw design ensures that nearly all mobile phase solvent can be used from the reservoir bottle, helping reduce waste and maintain uninterrupted analytical performance.

“Last Drop” Design – Maximum Solvent Utilization

• 22 mm flat filter geometry

• Sits at the lowest point in the bottle

• Draws solvent to near‑empty conditions

• Minimizes waste and prevents pump starvation

✅ Ideal for long runs, high‑volume solvent usage, and cost control

✅ Improves workflow efficiency and solvent utilization

5 µm Stainless Steel Element – High Capacity Filtration
