Thumbnail Filmstrip of Cellulose Acetate Syringe Filters, 1.2um, 13mm, Luer-Lok/Luer Slip, Sterile, 50/Pk Images
Featuring a naturally hydrophilic cellulose acetate membrane with a 1.2um pore size, these 13mm sterile syringe filters deliver fast, efficient clarification of aqueous, organic, and alcohol-based solutions. The membrane is housed in a modified acrylic body that supports the membrane bidirectionally, allowing both sample injection and aspiration, and the unit is configured with a Female Luer Lock inlet and Male Luer Slip outlet for secure connection to a wide range of syringes.
Key Cellulose Acetate Membrane Characteristics
- Naturally hydrophilic, wetting readily with aqueous solutions for consistent flow.
- Extremely low protein binding, helping preserve sample integrity and maximize recovery of dilute analytes.
- 1.2um pore size suited to clarification and particulate removal from heavier-loaded aqueous samples.
- Compatible with aqueous, alcohol, and many organic solutions for broad laboratory use.
Key Construction Characteristics
- Modified acrylic housing that bidirectionally supports the membrane for injection or aspiration.
- 13mm membrane diameter within an 18mm housing for low-volume sample handling.
- Female Luer Lock inlet and Male Luer Slip outlet connection.
- Supplied sterile, 50 filters per pack.
- Ultrasonically welded and integrity tested to ensure a proper seal and eliminate filter bypass.
Each filter is labeled with its specific membrane material and pore size for easy identification outside the original packaging. The low hold-up volume design reduces sample loss, while the integrity-tested weld delivers reliable, reproducible filtration that protects downstream instrumentation and maintains sample integrity.
