Polyethersulfone PES Syringe Filters, 0.45um, 4mm, Luer-Lok/Luer Slip, Sterile, 100/Pk SKU: SF18207

Polyethersulfone (PES) Syringe Filters - SF18207

Featuring pre-sterilized ultra-compact polyethersulfone membrane technology with 0.45µm pore size engineered for microscale clarification applications requiring immediate aseptic processing. Ready-to-use sterile 4mm format delivers reliable particulate removal for precious samples where minimal holdup volume is critical for sample recovery. Tisch Scientific provides precision filtration solutions combining hydrophilic PES membranes with miniaturized polypropylene housing to ensure efficient clarification in analytical method development, high-throughput screening, and microvolume biological sample preparation.

Key Polyethersulfone (PES) Membrane Characteristics

• Naturally hydrophilic membrane enabling instant filtration without pre-wetting steps
• Clarification-grade 0.45µm pore size removes cells, debris, and particulates
• Ultra-low protein binding preserving sample integrity in microscale volumes
• Membrane thickness of 100-160µm, providing consistent retention characteristics
• Chemical compatibility with aqueous solutions and mild organic solvents

Key Construction Characteristics

• Microscale 4mm diameter, optimized for minimal sample volume requirements
• Integrated PP prefilter protecting membrane and enhancing throughput capacity
• Exceptional holdup volume of only 1µL, maximizing precious sample recovery
• Universal Luer-Lok/Luer Slip connectivity compatible with precision syringes

SF18207 syringe filters maintain precise flow rates of 2ml through a 0.125cm² filtration area, perfectly engineered for your microscale applications requiring absolute clarity with minimal sample loss. A bubble point of 31.91psi validates membrane integrity for critical applications demanding documented performance in regulated environments. Pre-sterilized individual packaging eliminates preparation time while ensuring immediate use in aseptic applications, maintaining operational capability up to 60°C for your most critical microscale clarification needs.
