Thumbnail Filmstrip of Regenerated Cellulose Syringe Filters, 0.45um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk Images
Featuring a naturally hydrophilic regenerated cellulose membrane with a 0.45um pore size, these 25mm syringe filters deliver fast, low-extractable clarification of aqueous and organic samples. The membrane is housed in a durable polypropylene body with a Female Luer Lock inlet and Male Luer Slip outlet, providing a secure connection to standard syringes. Supplied nonsterile in a transparent housing and packaged 100 per pack, this PFAS-free construction supports trace-level analytical workflows where forever chemical interference must be avoided.
Key Regenerated Cellulose Membrane Characteristics
- Naturally hydrophilic membrane wets out readily for filtration of aqueous and aqueous-organic solutions without pre-wetting.
- Very low protein binding and low extractables help preserve sample integrity and minimize background interference.
- 0.45um pore size clarifies samples and removes fine particulates ahead of analysis.
- Broad chemical compatibility makes the membrane suitable for many solvents, buffers, and biological fluids.
- PFAS-free composition supports PFAS testing and trace contaminant analysis.
Key Construction Characteristics
- Polypropylene housing provides chemical durability and reliable mechanical strength.
- Female Luer Lock inlet and Male Luer Slip outlet (Luer-Lok/Luer Slip) for a secure syringe connection.
- 25mm membrane diameter sized for moderate sample volumes.
- Transparent housing allows visual monitoring of the sample during filtration.
- Nonsterile, packaged 100 per pack.
Each filter delivers consistent, reproducible flow for dependable sample preparation. The integrity-tested housing helps eliminate filter bypass, protecting downstream instruments and preserving sample integrity. The PFAS-free build makes these filters well suited to environmental and analytical laboratories focused on trace-level accuracy.
