PES Syringe Filters, 0.45um, 13mm, Luer-Lok/Luer Slip, Nonsterile, 500/Pk
GVS SKU: FJ13BNPPS004AD01

Featuring a naturally hydrophilic polyethersulfone (PES) membrane with a 0.45um pore size, these 13mm syringe filters deliver fast, efficient clarification of aqueous and organic solutions without added wetting agents that could interfere with analysis. The PES membrane is cast from pure polyethersulfone polymer, providing low protein and drug binding for maximum sample recovery, and is housed in a transparent polypropylene body with a Female Luer Lock inlet and Male Luer Slip outlet. Each unit is ultrasonically welded and supplied nonsterile, 500 per pack.

Key PES Membrane Characteristics

• Naturally hydrophilic structure wets out without added surfactants, eliminating extractables that can compromise results.
• Low protein and drug binding maximizes recovery of critical analytes in life science work.
• Asymmetric microporous structure supports high throughput and fast flow rates.
• Acid and base resistant polyethersulfone polymer offers a wide chemical compatibility range.
• Strong, durable membrane withstands aggressive handling and automated equipment.

Key Construction Characteristics

• Transparent polypropylene housing, 18mm housing diameter, ultrasonically welded for integrity.
• Female Luer Lock inlet and Male Luer Slip outlet (Luer-Lok/Luer Slip) connection.
• 0.76 cm squared effective filtration area with a holdup volume of less than 50 microliters.
• Maximum operating temperature of 90C and maximum operating pressure of 80 psi.
• Nonsterile, supplied 500 per pack.

These filters provide reliable, reproducible clarification while preserving sample integrity. The low binding membrane and low holdup volume help retain valuable analytes, and the welded polypropylene housing maintains a leak free seal during pressurized filtration. The result is consistent particulate removal suited to demanding analytical and life science preparation.
