Thumbnail Filmstrip of Cellulose Acetate Syringe Filters, 0.22um, 13mm, Luer-Lok/Luer Lok, Sterile, 50/Pk Images
Featuring a naturally hydrophilic Cellulose Acetate (CA) membrane with a 0.22um pore size, these 13mm sterile syringe filters deliver fast, efficient clarification and sterilizing-grade filtration of aqueous and biological samples. The membrane is housed in an ultrasonically welded acrylic body measuring 18mm in housing diameter, with an effective filtration area of 0.76 cm² and a holdup volume of less than 50 microliters that minimizes sample loss. Female Luer Lock inlet and Male Luer Lock outlet connections provide a secure, leak-resistant fit, and each filter arrives sterile in a pack of 50.
Key Cellulose Acetate Membrane Characteristics
- Naturally hydrophilic membrane wets readily for filtration of aqueous and biological solutions.
- Low protein binding helps preserve sample integrity and recovery during processing.
- 0.22um pore size provides sterilizing-grade retention for tissue culture media, buffers, and protein solutions.
- Suited to filtration of aqueous, organic, and alcohol solutions.
- Each filter is labeled with the specific membrane material and pore size for easy identification.
Key Construction Characteristics
- Ultrasonically welded acrylic housing with an 18mm housing diameter and 13mm membrane diameter.
- Female Luer Lock inlet and Male Luer Lock outlet for secure syringe connection.
- Effective filtration area of 0.76 cm² with a holdup volume under 50 microliters.
- Maximum operating temperature of 50°C and maximum operating pressure of 80 psi.
- Supplied sterile, 50 filters per pack.
Integrity-tested construction ensures a proper filter fit and weld to eliminate potential filter bypass, supporting reliable, reproducible results. The low holdup volume and bidirectional membrane support help maintain sample integrity during both injection and aspiration. These filters deliver consistent performance across analytical sample preparation, chromatography prep, and cell culture workflows.
