Thumbnail Filmstrip of Polyethersulfone (PES) Syringe Filters, 0.45um, 13mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk Images
Featuring a naturally hydrophilic polyethersulfone (PES) membrane rated at 0.45um, this 13mm syringe filter delivers fast, reliable clarification of aqueous and mildly organic samples. The membrane is housed in a transparent polypropylene body with a Female Luer Lock inlet and Male Luer Slip outlet, providing a secure, leak-tight connection to standard syringes. Supplied nonsterile in packs of 100, each filter is individually labeled with its membrane material and pore size for easy identification once removed from packaging.
Key Polyethersulfone (PES) Membrane Characteristics
- Naturally hydrophilic structure wets out readily for filtration of aqueous solutions and buffers without pre-wetting
- Very low protein and drug binding maximizes sample recovery for sensitive analyses
- Broad chemical compatibility across acids, bases, and many solvents
- 0.45um rating removes particulates to clarify samples and protect downstream instrumentation
- High strength and dimensional stability that withstands aggressive handling and automated equipment
Key Construction Characteristics
- Transparent polypropylene housing for visual monitoring of filtration
- Female Luer Lock inlet and Male Luer Slip outlet for secure syringe attachment
- 13mm membrane diameter within an 18mm housing diameter
- Ultrasonically welded construction, integrity tested to eliminate filter bypass
- Nonsterile, supplied 100 per pack
This filter provides consistent particulate removal and clarification while maintaining sample integrity through its low-binding PES membrane. The robust polypropylene housing and welded seal deliver dependable performance under routine bench and automated workflows. Each unit supports reproducible sample preparation for analytical and life science applications.
