Millipore Filter with Quick-Connect and 1/4 in. Barb Total of 7 Assemblies

Millipore Millex-FG 50 mm In-Line Vacuum Protection Filter Assembly – 0.2 Micron, Hydrophobic PTFE Fluoropore Membrane, Bi-Directional, with Quick Connector and 1/4 Inch Hose Barb, Autoclavable (MPN: SLFG05010)

The Millipore SLFG05010 (also cataloged as Millex-FG or cross-listed as MIL-SLFG05010) is a high-performance, laboratory-grade in-line gas and vent filtration assembly precision-engineered to protect vacuum pumps, transducers, and fluid lines from moisture damage and biological contamination. Molded from robust, solvent-inert polypropylene, this 50 mm diameter filter capsule features a high-purity hydrophobic PTFE Fluoropore membrane with a definitive 0.2 micron pore size rating. The assembly comes pre-configured with a dual stepped hose barb inlet/outlet connection featuring an integrated quick connector adapter matching 1/4 inch interior diameter flexible latex, silicone, or Masterflex pump tubing. Designed with bi-directional fluidic mechanics, this autoclave-safe vent filter establishes a reliable physical barrier that handles working pressures up to 60 psi (4.1 bar) without airflow stalling.

Technical Performance and Design

• Hydrophobic PTFE Fluoropore Membrane: Outfitted with a high-surface-area hydrophobic polytetrafluoroethylene matrix providing 19.6 square centimeters of pure filtration space. This membrane allows gases to pass at high flow rates (minimum 15 liters per minute at 5 psi) while aggressively blocking aqueous liquids, aerosols, and airborne particulates down to 0.2 microns.

• Integrated Quick Connect Barb Assembly: Pre-assembled with stepped hose barb adapters engineered to secure an immediate, airtight physical grip onto standard 1/4 inch inner diameter laboratory transfer hoses. The specialized quick-connector mechanism enables rapid line snap-on disconnect transitions without cutting tubing rows.

• Bi-Directional Fluid Flow Geometry: Engineered with fully symmetric internal flow channels, enabling air or gas to filter with equal precision and speed in either physical direction. This architecture removes mounting alignment errors inside busy multi-pump cabinet loops.

• Autoclavable Polypropylene Housing: The heavy-wall outer shell is fabricated from premium translucent polypropylene rated to withstand continuous internal pressures up to 60 psi. The entire filter housing profile is fully compatible with steam autoclaving routines up to 121 C for multi-run deployment protocols.

Key Benefits and Applications

• Vacuum Line and Pump Protection: The industry-standard barrier choice positioned between aspiration collection flasks and house vacuum line networks, preventing corrosive liquid back-streaming or moisture pull from ruining pump motors.

• Sterile Tank and Fermenter Venting: Serves as an excellent sterile gas vent filter mounted to large bioreactor head plates, carboys, or pilot bottles, cleaning the incoming ambient air supply while preventing internal spray exhaust leakage.

• Aggressive Organic Solvent Clarification: Extreme chemical resistance allows these capsules to cleanly filter, clarify, and particle-scrub corrosive organic solutions, strong acids, and HPLC-grade mobile phase solvents.

• Transducer and Gauge Isolation: Extensively utilized across inline fluidic engineering and hemodialysis lines to safeguard expensive pressure gauges and sensors from liquid contact and pressure-line moisture tracking.
