Thumbnail Filmstrip of Regenerated Cellulose Syringe Filters, 0.7/0.22um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 50/Pk Images
Featuring a hydrophilic Regenerated Cellulose final membrane backed by two layers of glass fiber prefilter, this 25mm syringe filter handles high particulate content liquids without clogging. The 0.7um glass fiber prefilters capture sediment and grit while the 0.22um Regenerated Cellulose membrane delivers fine final filtration, allowing smooth, low-force filtration even with difficult samples. The clear polypropylene housing provides a 4.63 cm2 effective filtration area, withstands a maximum operating temperature of 90C (194F), and tolerates a maximum operating pressure of 75 psi.
Key Regenerated Cellulose Membrane Characteristics
- Naturally hydrophilic Regenerated Cellulose membrane provides excellent wettability for aqueous and many organic samples.
- 0.22um final pore rating delivers fine clarification and consistent sample purity.
- Dual glass fiber prefilter layers (0.7um nominal) capture heavy sediment, extending membrane life and increasing throughput.
- Low protein and analyte binding supports recovery-sensitive sample preparation.
- Broad compatibility suited to viscous and heavily loaded samples.
Key Construction Characteristics
- Clear polypropylene housing with bidirectional membrane support for sample injection or aspiration.
- Luer-Lok inlet and Luer Slip outlet connections for secure syringe attachment.
- Effective filtration area of 4.63 cm2 with a housing diameter of 30mm and membrane diameter of 25mm.
- Nonsterile, supplied 50 per pack.
- Maximum operating temperature of 90C (194F) and maximum operating pressure of 75 psi.
This filter maintains reliable performance across challenging, high-solids samples by combining staged prefiltration with a fine final membrane. The integrity-tested construction helps eliminate filter bypass, protecting sample integrity and downstream instrumentation. The result is faster, lower-effort filtration and a cleaner sample every time.
