Catalog Number - 58846-05-002

58846-05-002 ARE‑Applied Research Mobile Phase Inlet Filters are high‑performance, biocompatible solvent filtration devices designed for HPLC, UHPLC, and LC‑MS mobile phase delivery systems, providing maximum solvent recovery, high throughput, and dependable instrument protection.

These filters incorporate a “Last Drop” flat‑profile design, allowing nearly complete use of solvent in reservoir bottles—an important benefit for long analytical runs, overnight sequences, and high‑volume workflows.

Each filter is constructed with a 5 µm PTFE filter element and an inert PEEK / PTFE wetted flow path, ensuring excellent chemical compatibility, low extractables, and stable performance across a wide range of applications.

“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

• Reduces waste and minimizes risk of run interruption

✅ Ideal for high‑throughput labs and long analytical sequences

✅ Improves solvent efficiency and workflow continuity

5 µm PTFE Element – High Capacity Filtration

• Removes particulates ≥ 5 µm

• Protects:

  • Pump seals and check valves

  • Injection systems

  • HPLC columns and detectors

• Larger pore size provides:

  • Higher flow rates

  • Lower backpressure impact

  • Extended service life

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

Visual Inspection Advantage – White Filter Element

• White PTFE surface enhances visibility of trapped particles

• Enables quick inspection of contamination buildup

• Helps maintain optimal flow by signaling replacement timing

✅ Supports proactive system maintenance

PEEK / PTFE Flow Path – High Purity Performance

• Wetted components made from:

  • PEEK (polyether ether ketone)

  • PTFE (inert fluoropolymer)

• Provides:

  • Chemical inertness

  • Minimal extractables

  • Broad solvent compatibility

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

1/16" Connector with ETFE Ferrule – Secure Integration

• Integrated 1/16" tubing connector

• Includes ETFE ferrule for non‑flanged tubing

• Ensures secure, leak‑free connection

• No additional fittings required

✅ Enables fast, reliable low‑pressure system setup

Performance Advantages – Modern HPLC Operation

Compared to smaller pore filters:

• Lower flow restriction for improved throughput

• Reduced likelihood of clogging in high‑flow applications

• Maintains consistent mobile phase delivery

• Extends filter lifespan between replacements

✅ Supports efficient and stable chromatography performance
