Additional Info:
58846-06-002 ARE‑Applied Research Mobile Phase Inlet Filters are high‑performance, biocompatible solvent filtration devices engineered for HPLC, UHPLC, and LC‑MS mobile phase delivery systems, providing very high flow capacity, maximum solvent recovery, and critical instrument protection.
These filters utilize a “Last Drop” flat‑profile design, enabling nearly complete withdrawal of mobile phase from reservoir bottles. This is especially valuable for high‑flow systems, long analytical runs, overnight sequences, and costly solvent systems.
Each filter is built with a 5 µm PTFE filter element and an inert PEEK / PTFE wetted flow path, ensuring excellent chemical compatibility, low extractables, and consistent performance across demanding analytical workflows.
✅ Explore bulk quantity options for lab standardization and cost efficiency
“Last Drop” Design – Maximum Solvent Utilization
Flat bottom‑draw filter geometry
Designed to sit at the lowest point in the bottle
Draws solvent to near‑dry conditions
Reduces solvent waste and prevents pump starvation
✅ Ideal for high‑throughput labs and high‑flow applications
✅ Improves workflow efficiency and run continuity
5 µm PTFE Element – High Flow / High Capacity Filtration
Removes particles ≥ 5 µm
Protects:
Pump seals and check valves
Injection systems
Columns and detectors
Larger pore size provides:
Very high flow rates
Low backpressure contribution
