PES Syringe Filters, 0.45um, 13mm, Luer-Lok/Luer Slip, Sterile, 50/Pk
GVS SKU: FJ13BSCPS004AL01

Featuring a naturally hydrophilic polyethersulfone (PES) membrane in a transparent acrylic housing, these syringe filters deliver rapid clarification of aqueous and organic solutions with low protein binding and broad chemical compatibility. Each unit carries a 0.45um membrane across a 13mm membrane diameter (18mm housing diameter), terminating in a Female Luer Lock inlet and Male Luer Slip outlet for a secure syringe connection. The filters are supplied sterile, 50 per pack, and ship ultrasonically welded and integrity tested.

Key PES Membrane Characteristics

• Naturally hydrophilic for fast wetting and high flow rates with aqueous and alcoholic media.
• Very low protein and drug binding to maximize recovery of critical analytes.
• Broad chemical compatibility across acids, bases, oxidants, serums, solvents, and fine chemicals.
• 0.45um rated pore size suited to general particulate removal and sample clarification.
• Strength and dimensional stability that withstand aggressive handling and automated equipment.

Key Construction Characteristics

• Transparent acrylic housing with bidirectional membrane support for sample injection or aspiration.
• Female Luer Lock inlet and Male Luer Slip outlet (Luer-Lok/Luer Slip) connection.
• Supplied sterile, packaged 50 per pack.
• Ultrasonically welded and integrity tested to eliminate filter by-pass.
• Each filter labeled with the specific membrane material and pore size for identification outside its packaging.

The low-protein-binding PES medium maintains sample integrity while delivering consistent, repeatable flow, making it well suited to demanding analytical workflows. Reliable welds and integrity testing help ensure that filtered samples reach downstream instruments free of particulate carryover.
