Thumbnail Filmstrip of Cellulose Acetate Syringe Filters, 0.45um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 10/Pk Images
Featuring a multilayer construction that combines graded glass fiber prefilters with a 0.45um hydrophilic cellulose acetate final membrane, these 25mm PFAS-free syringe filters deliver high-throughput clarification of heavily loaded and viscous samples. The integrated prefiltration stack separates sediment and grit upstream of the cellulose acetate membrane, allowing the syringe to be pushed smoothly even with difficult samples while maintaining a low-protein-binding final barrier. Each filter uses a clear polypropylene housing with Luer-Lok inlet and Luer Slip outlet fittings, is supplied nonsterile, and is packaged 10 per pack.
Key Cellulose Acetate Membrane Characteristics
- Naturally hydrophilic membrane that wets readily with aqueous solutions for fast, consistent flow.
- Low protein binding for maximum recovery of proteins, enzymes, and other biomolecules of interest.
- 0.45um rated final membrane suited to sample clarification and particulate removal ahead of analysis.
- Graded glass fiber prefilter stack provides multi-level interception of contaminants for high particulate loading.
- Low extractables to help preserve sample integrity for downstream analytical work.
Key Construction Characteristics
- Clear polypropylene housing with a 25mm membrane and 4.63 cm2 effective filtration area.
- Luer-Lok inlet and Luer Slip outlet connections for compatibility with most standard syringes.
- Supplied nonsterile, 10 filters per pack.
- Maximum operating temperature of 90 C (194 F).
- Maximum operating pressure of 75 psi.
The multilayer prefilter and final membrane design lets one filter do the work of several standard syringe filters, reducing clogging and plastic use when processing challenging samples. The hydrophilic, low-binding cellulose acetate membrane helps preserve sample integrity and maximize analyte recovery. PFAS-free construction supports applications where background contamination must be minimized.
