Catalog Number - 58846-07-002

58846-07-002 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, delivering maximum solvent recovery, very high flow capacity, and critical instrument protection.

These filters incorporate a “Last Drop” flat‑profile design, allowing nearly complete withdrawal of mobile phase from reservoir bottles—an essential advantage for high‑flow applications, long analytical runs, overnight sequences, and costly solvent systems.

Each unit 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 in demanding analytical environments.

✅ Explore bulk options for lab standardization and high‑throughput workflows

“Last Drop” Design – Maximum Solvent Utilization

• Wide 22 mm flat filter geometry

• Designed to sit at the lowest point in the bottle

• Draws solvent to near‑empty conditions

• Reduces waste and prevents pump starvation

✅ Ideal for high‑flow systems and long analytical sequences

✅ Improves efficiency and solvent cost control

5 µm PTFE Element – High Flow / High Capacity Filtration

• Filters particles ≥ 5 µm

• Protects:

  • Pump seals and check valves

  • Injection systems

  • HPLC columns and detectors

• Larger pore size provides:

  • Very high flow rates

  • Low restriction / minimal backpressure

  • Extended service life

✅ Ideal for high‑flow applications or pre‑filtered mobile phases

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 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 and leachables

  • Broad solvent compatibility

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

Tripod Connector – Universal, Tool‑Free Integration

• All‑PEEK tripod tubing connector

• Accepts:

  • 1/16" OD tubing

  • 1/8" OD tubing

• No ferrules or nuts required

• Simple push‑fit tubing installation

✅ Enables fast setup and flexible system configuration

Performance Advantages – Modern HPLC Operation

Compared to finer‑pore inlet filters:

• Lower flow resistance for improved throughput

• Reduced clogging risk in high‑flow applications

• Stable solvent delivery at elevated flow rates

• Extended maintenance intervals

✅ Aligns with best practices for high‑efficiency chromatography systems

System Compatibility & Use

Designed for use with:

• HPLC / UHPLC mobile phase systems

• LC‑MS solvent delivery setups
