Thumbnail Filmstrip of Cellulose Acetate Syringe Filters, 5.0um, 13mm, Luer-Lok/Luer Lok, Sterile, 50/Pk Images
Featuring a naturally hydrophilic cellulose acetate membrane with a 5.0um pore size, these 13mm sterile syringe filters deliver fast, low-protein-binding filtration of aqueous and biological samples. The membrane is mounted in an ultrasonically welded 18mm acrylic housing with a Female Luer Lock inlet and Male Luer Lock outlet, and each filter is supplied sterile in packs of 50.
Key Cellulose Acetate Membrane Characteristics
- Naturally hydrophilic membrane wets out readily for rapid filtration of aqueous and biological solutions.
- Low protein binding helps preserve sample integrity and maximize analyte recovery.
- 5.0um pore size suited to clarification and removal of larger particulates ahead of analysis.
- Made from pure cellulose without wetting agents, providing chemical resistance to a wide variety of solvents.
- High wet strength supports reliable handling during use.
Key Construction Characteristics
- Ultrasonically welded 18mm acrylic housing with a 13mm membrane diameter.
- Female Luer Lock inlet and Male Luer Lock outlet for a secure, leak-resistant connection.
- Effective filtration area of 0.76 cm² with a holdup volume under 50 microliters.
- Rated to a maximum operating temperature of 50C (122F) and a maximum operating pressure of 80 psi.
- Supplied sterile, integrity tested, and individually labeled with material and pore size; 50 per pack.
The welded housing is integrity tested to ensure a proper filter fit and eliminate potential filter by-pass, supporting consistent, reproducible results. The low holdup volume minimizes sample loss, while the hydrophilic, low-binding membrane maintains sample integrity across routine preparation workflows.
