Nylon Syringe Filters, w/ Glass PreFilter, 0.45um, 25mm, Luer-Lok/Luer Slip, 100Pk SKU: SF18164

Nylon Syringe Filters - SF18164

The SF18164 nylon syringe filters feature a 25mm diameter configuration with 0.45µm pore size and integrated glass pre-filter, delivering superior sample clarification and particulate removal for routine analytical applications. Tisch Scientific syringe filters excel at processing standard volume samples with high particulate loads, as the glass pre-filter extends membrane life by capturing larger particles before they reach the primary filtration surface. SF18164 filters provide consistent performance across diverse sample matrices, making them ideal for laboratories requiring reliable clarification without frequent filter changes.

Key Nylon Membrane Characteristics

• 0.45µm primary filtration effectively removes fine particulates, cellular debris, and suspended solids while preserving dissolved analytes and proteins in solution
• Integrated glass fiber pre-filter captures coarse particles and extends primary membrane life, enabling filtration of samples with higher particulate loads
• Naturally hydrophilic membrane enables immediate filtration of aqueous solutions without pre-wetting, maintaining consistent flow rates throughout processing cycles
• Broad chemical compatibility supports filtration of both aqueous and organic solvents, accommodating diverse analytical workflows from environmental testing to pharmaceutical analysis
• Temperature stability to 100°C permits processing of heated samples and enables autoclave sterilization at 121°C when sterile conditions are required

Key Construction Characteristics

• Robust polypropylene housing provides excellent chemical resistance and structural integrity, withstanding operating pressures up to 87 psi burst pressure
• 25mm diameter format delivers optimal filtration area for standard volume samples, balancing throughput efficiency with economical filter usage
• Universal Luer-Lok/Luer Slip connections ensure secure syringe attachment and compatibility with standard laboratory filtration equipment
• Dual-layer design combines glass pre-filtration with nylon membrane filtration for extended service life and consistent performance

SF18164 syringe filters deliver the enhanced performance your laboratory needs when processing challenging samples with high particulate content. Tisch Scientific's combination of glass pre-filtration and 0.45µm nylon membrane technology ensures you'll achieve extended filter life and consistent flow rates throughout your filtration procedures. Your research benefits from the dual-layer design that reduces filter consumption while maintaining the sample clarity and quality your analytical methods demand.
