Catalog Number - 58846-E-02-002

58846-E-02-002 ARE‑Applied Research Mobile Phase Inlet Filters are economy, biocompatible, all‑PTFE filtration devices designed for HPLC, UHPLC, and LC‑MS mobile phase delivery systems, offering high filtration efficiency and maximum solvent utilization at a lower cost point.

These filters use a “Last Drop” flat bottom‑draw design, allowing nearly complete withdrawal of solvent from reservoir bottles—minimizing waste and supporting uninterrupted chromatographic runs.

Constructed entirely of PTFE, these filters provide excellent chemical resistance, low extractables, and compatibility with sensitive analytical workflows, while offering flexibility for custom tubing configurations.

“Last Drop” Design – Maximum Solvent Utilization

• 22 mm flat filter geometry

• Sits at the lowest point in the reservoir bottle

• Draws solvent to near‑empty conditions

• Reduces waste and avoids pump starvation

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

✅ Improves lab efficiency and continuity

2.5 µm PTFE Element – Biocompatible Filtration

• Removes particles ≥ 2.5 µm (commonly protects against ~2 µm+ particulates)

• Protects:

  • Pump seals and check valves

  • Injection systems

  • Columns and detectors

• PTFE media provides:

  • Broad chemical compatibility

  • Biocompatibility

  • Low adsorption and extractables

✅ Suitable for LC‑MS, pharmaceutical, and general HPLC workflows

All‑PTFE Construction – Maximum Chemical Compatibility

• Fully PTFE wetted surfaces

• No mixed‑material flow path

• Highly inert and resistant to aggressive solvents

✅ Ideal for high‑purity and sensitive analytical applications

Visual Inspection Advantage – White Filter Element

• White PTFE enhances visibility of trapped particles

• Enables quick contamination assessment

• Supports timely replacement decisions

✅ Improves maintenance efficiency and system uptime

Tubing Compatibility – Flexible System Integration

• Designed for 1/8" low‑pressure tubing systems

• Requires user‑configured tubing attachment

• Compatible with custom and simplified setups

✅ Ideal for labs requiring flexibility in tubing configurations
