PES Syringe Filters, 0.45um, 25mm, Luer-Lok/Luer Slip, Sterile, 50/Pk
GVS SKU: FJ25BSCPS004AL01

Featuring a naturally hydrophilic polyethersulfone (PES) membrane rated at 0.45um, these sterile syringe filters deliver fast, high-throughput clarification of aqueous and organic solutions. The 25mm membrane is held within a transparent acrylic housing that bidirectionally supports the membrane, and each unit is ultrasonically welded and integrity tested to eliminate filter by-pass. A Female Luer Lock inlet and Male Luer Slip outlet provide secure connection to standard syringes, while an effective filtration area of 4.4 cm2 and low hold-up volume maximize sample recovery.

Key PES Membrane Characteristics

• Naturally hydrophilic PES membrane wets quickly without the need for pre-wetting
• Low protein binding helps preserve sensitive analytes and improves sample recovery
• 0.45um pore size provides reliable clarification and particulate removal
• Suited for aqueous, alcohol, and organic solutions across a broad range of routine and analytical work
• Typical bubble point of 45 psi (water) confirms membrane integrity

Key Construction Characteristics

• Transparent modified acrylic housing bidirectionally supports the membrane
• Female Luer Lock inlet and Male Luer Slip outlet for secure syringe attachment
• Supplied sterile and individually packaged, 50 filters per pack
• 25mm membrane diameter with 33mm housing diameter and 4.4 cm2 effective filtration area
• Maximum operating pressure of 5 bar (approximately 75 psi)

These filters deliver consistent, reproducible filtration with a typical water flow rate of 100 ml/min at 15 psi and 23 degrees C. The low hold-up volume and integrity-tested welds protect sample integrity and minimize loss, making them dependable for sensitive analytical and biological workflows.
