Thumbnail Filmstrip of Cellulose Acetate Syringe Filters, 0.45um, 13mm, Luer-Lok/Luer Lok, Nonsterile, 100/Pk Images
Featuring a naturally hydrophilic cellulose acetate membrane, these PFAS-free syringe filters deliver fast, efficient clarification of aqueous, organic, and alcohol-based solutions. The 0.45um pore size removes particulates and microorganisms ahead of analysis, while the 13mm membrane diameter suits small sample volumes and minimizes hold-up. An ultrasonically welded acrylic housing supports the membrane bidirectionally, allowing both sample injection and aspiration, and each unit terminates in a Luer-Lok inlet and Luer Lok outlet for secure connection.
Key Cellulose Acetate Membrane Characteristics
- Naturally hydrophilic: Wets out readily for fast, even flow of aqueous and alcohol solutions without surfactant treatment.
- Low protein binding: Cellulose acetate minimizes nonspecific adsorption, helping preserve sample integrity for protein and biological work.
- 0.45um pore size: Removes fine particulates and microorganisms for sample clarification ahead of chromatographic analysis.
- PFAS-free construction: Manufactured without per- and polyfluoroalkyl substances for cleaner sample handling.
- Broad solution compatibility: Suited to aqueous, organic, and alcohol solutions across routine lab workflows.
Key Construction Characteristics
- Housing: Modified acrylic housing, yellow, that bidirectionally supports the membrane for injection or aspiration.
- Connection: Luer-Lok inlet and Luer Lok outlet (FLL/MLL) for a secure, leak-resistant fit.
- Membrane diameter: 13mm, ideal for low-volume and costly samples with reduced hold-up.
- Sterility: Nonsterile.
- Packaging: Supplied 100 per pack.
Ultrasonic welding and integrity testing help ensure a proper filter fit and eliminate potential filter by-pass for consistent, reliable performance. The low hold-up volume design protects costly or limited samples, while the naturally hydrophilic membrane maintains steady flow and sample integrity throughout filtration.
