Thumbnail Filmstrip of Cellulose Acetate Syringe Filters, 0.22um, 25mm, Luer-Lok/Luer Slip, Sterile, 50/Pk Images
Featuring a naturally hydrophilic cellulose acetate membrane, these sterile syringe filters deliver fast, efficient clarification and sterilizing-grade filtration of aqueous and organic solutions. The 0.22um membrane is housed in a 25mm format within a 33mm modified acrylic housing that bidirectionally supports the membrane, while Female Luer Lock inlet and Male Luer Slip outlet fittings connect securely to standard syringes. With an effective filtration area of 4.6 cm squared and a holdup volume under 100 microliters, each unit minimizes sample loss while maximizing recovery.
Key Cellulose Acetate Membrane Characteristics
- Naturally hydrophilic membrane wets readily for fast, consistent flow with aqueous samples.
- Low protein binding helps preserve sample integrity and improve analyte recovery.
- 0.22um rating provides sterilizing-grade retention for clarification and microbiological work.
- Suited to filtration of aqueous and alcohol solutions, buffers, and biological fluids.
Key Construction Characteristics
- Modified acrylic housing, ultrasonically welded and integrity tested to eliminate filter bypass.
- Female Luer Lock inlet and Male Luer Slip outlet for secure syringe connection.
- Supplied sterile, 50 filters per pack, with each unit labeled with membrane material and pore size.
- Maximum operating temperature of 50 degrees C (122 degrees F) and maximum operating pressure of 80 psi.
- 33mm housing diameter, 25mm membrane diameter, with effective filtration area of 4.6 cm squared.
These filters maintain reliable, reproducible performance across routine sample preparation workflows. The integrity-tested weld and labeled housing support consistent results and easy identification at the bench. Low holdup volume and a generous filtration area help protect sample integrity while sustaining high throughput.
