Thumbnail Filmstrip of Regenerated Cellulose Syringe Filters, 0.22um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 500/Pk Images
Featuring a naturally hydrophilic 0.22um regenerated cellulose membrane housed in a transparent polypropylene shell, these 25mm syringe filters deliver rapid, low-extractable filtration of aqueous and organic samples. The regenerated cellulose medium is made from pure cellulose without wetting agents, providing broad chemical resistance and high wet strength for demanding sample preparation. Each unit pairs a Female Luer Lock inlet with a Male Luer Slip outlet for secure attachment to standard syringes, and the membrane carries a 0.22um pore rating suitable for sterilizing-grade clarification of compatible solutions.
Key Regenerated Cellulose Membrane Characteristics
- Naturally hydrophilic surface wets out readily for aqueous and alcohol-based samples without added wetting agents.
- Manufactured from pure cellulose, delivering low extractables and minimal sample interference.
- Broad chemical resistance to a wide variety of solvents, supporting both aqueous and organic mobile phases.
- High wet strength maintains membrane integrity under pressure during filtration.
- 0.22um pore size provides fine clarification and sterilizing-grade retention for compatible fluids.
Key Construction Characteristics
- Transparent polypropylene housing, ultrasonically welded and integrity tested to eliminate filter by-pass.
- Female Luer Lock inlet and Male Luer Slip outlet (Luer-Lok/Luer Slip) for compatibility with standard syringes.
- 25mm membrane diameter with a 33mm housing diameter and 4.6 cm2 effective filtration area.
- Holdup volume of less than 100 microliters minimizes sample loss for costly or small-volume samples.
- Nonsterile, supplied 500 per pack, with each filter labeled by membrane material and pore size.
These filters maintain consistent flow and reliable retention across aqueous and organic solutions, protecting downstream instruments and preserving sample integrity. The low holdup volume and pure cellulose construction reduce analyte loss and contamination, supporting reproducible results in analytical workflows.
