Catalog Number - 58835-20

58835-20 ARE‑Applied Research Mobile Phase Inlet Filter is a high‑capacity, economy solvent filtration device built for HPLC, UHPLC, and LC‑MS mobile phase delivery systems, offering maximum solvent recovery, extremely low flow restriction, and durable system protection.

This filter features a “Last Drop” flat bottom‑draw design, enabling nearly complete use of solvent from reservoir bottles—ideal for high‑throughput environments, long analytical sequences, and bulk solvent operations.

Constructed with a 10 µm stainless steel filter element and PEEK / PTFE structural components, this filter provides excellent mechanical strength, chemical compatibility, and long service life in demanding laboratory conditions.

✅ Compatible across multiple tubing sizes with simple push‑fit installation

“Last Drop” Design – Maximum Solvent Utilization

• Wide 22 mm flat filter geometry

• Positions at the lowest point in the bottle

• Draws solvent to near‑empty conditions

• Minimizes waste and prevents pump starvation

✅ Ideal for bulk solvent use and extended analytical runs

✅ Improves efficiency and solvent cost control

10 µm Stainless Steel Element – Ultra‑High Flow Capacity

• Filters particles ≥ 10 µm

• Protects:

  • Pump seals and check valves
