Thumbnail Filmstrip of Cellulose Acetate Syringe Filters, 0.22um, 13mm, Luer-Lok/Luer Lok, Nonsterile, 100/Pk Images
Featuring a naturally hydrophilic cellulose acetate (CA) membrane with a 0.22um pore size, these PFAS-free syringe filters deliver fast, efficient sterile filtration and clarification of aqueous and organic samples. The 13mm membrane is housed in an 18mm acrylic body that is ultrasonically welded for a leak-resistant seal, and the unit connects through a Female Luer Lock inlet and Male Luer Lock outlet (Luer-Lok/Luer Lok). The membrane provides an effective filtration area of 0.76 cm2 with a holdup volume of less than 50 microliters to conserve small or costly samples. Supplied nonsterile, 100 per pack.
Key Cellulose Acetate Membrane Characteristics
- Naturally hydrophilic, making it suitable for both aqueous and organic samples without added wetting agents.
- Very low protein binding for high analyte recovery and reliable downstream analysis.
- Broad chemical resistance to a wide variety of solvents with high wet strength.
- Operates across a pH range of approximately 3 to 12.
- 0.22um rated pore size supports sterilizing-grade and fine clarification filtration.
Key Construction Characteristics
- Acrylic housing, ultrasonically welded to eliminate potential filter bypass.
- 13mm membrane diameter within an 18mm housing diameter.
- Female Luer Lock inlet and Male Luer Lock outlet (Luer-Lok/Luer Lok) connection.
- Effective filtration area of 0.76 cm2 with a holdup volume under 50 microliters.
- Nonsterile, PFAS-free, blue color coded, 100 per pack.
Each filter is integrity tested to ensure a proper fit and weld, maintaining sample integrity throughout filtration. The low holdup volume minimizes sample loss, while the broad chemical compatibility of the cellulose acetate membrane protects analyte recovery across diverse aqueous and organic matrices. This combination delivers consistent, reliable performance in routine sample preparation.
