Catalog Number - 58846-01-002

58846-01-002 ARE‑Applied Research Mobile Phase Inlet Filters are high‑capacity, biocompatible solvent filtration devices engineered for HPLC, UHPLC, and LC‑MS mobile phase delivery systems, providing maximum solvent recovery, ultra‑low flow restriction, and dependable protection of critical instrument components.

These filters utilize a “Last Drop” flat bottom‑draw design, enabling nearly complete withdrawal of solvent from reservoir bottles—an important advantage for high‑throughput workflows, long analytical sequences, and bulk solvent handling where minimizing waste and preventing system interruptions is essential.

Each unit is constructed with a 10 µm PTFE filter element and an inert PEEK / PTFE wetted flow path, ensuring excellent chemical compatibility, minimal extractables, and extended service life in demanding analytical environments.

“Last Drop” Design – Maximum Solvent Utilization

• Wide 22 mm flat bottom‑draw geometry

• Designed to sit at the lowest point in the bottle

• Draws solvent to near‑empty conditions

• Minimizes waste and prevents pump run‑dry events

✅ Ideal for high‑volume solvent applications and long analytical runs

✅ Improves efficiency and solvent cost control

10 µm PTFE Element – Ultra‑High Flow Capacity

• Filters particles ≥ 10 µm

• Protects:

  • Pump seals and check valves

  • Injection systems

  • HPLC columns and detectors

• Larger pore size provides:

  • Maximum flow capacity

  • Minimal restriction / lowest backpressure

  • Longest service life among filter options

✅ Ideal for pre‑filtered solvents and high‑flow systems

Visual Inspection Advantage – White Filter Element

• White PTFE surface enhances visibility of trapped particles

• Enables quick contamination assessment

• Helps determine optimal replacement timing

✅ Supports proactive maintenance and consistent performance

PEEK / PTFE Flow Path – High Purity Performance

• Wetted materials:

  • PEEK (polyether ether ketone)

  • PTFE (inert fluoropolymer)

• Provides:

  • Chemical inertness

  • Low extractables and leachables

  • Broad solvent compatibility

✅ Suitable for LC‑MS, analytical, and biocompatible workflows

Tripod Connector – Universal, Tool‑Free Integration
