Polyethersulfone (PES) Syringe Filters - SPEC18107

Biotechnology and pharmaceutical laboratories demand contamination-free clarification solutions for samples containing cellular debris and large aggregates. Polyethersulfone technology in SPEC18107 delivers 3.0µm filtration with gamma sterilization, ensuring sample integrity while removing coarse particulates from sensitive biological preparations. Premium construction features polypropylene housing rated for 80°C continuous operation, secured by dual Luer Lock interfaces providing reliable performance throughout demanding protocols requiring 72.5psi operating pressure.

Key PES Membrane Characteristics

• Preserves proteins through inherently low binding surface interactions with biomolecules
• Sterile packaging eliminates contamination risks during aseptic sample processing
• Hydrophilic membrane permits direct aqueous filtration without solvent preconditioning
• 3.0µm porosity removes large aggregates while allowing smaller molecules to pass
• Maintains concentration of dissolved analytes during particle removal procedures

Key Construction Characteristics

• Minimizes loss of valuable reagents with retention volume under 150µl specification
• 4.08cm² membrane surface enables efficient flow for samples ranging from 10 to 100 mL
• Female and male Luer connections accommodate diverse syringe configurations securely
• Resists common laboratory chemicals through inert polypropylene housing construction

SPEC18107 supports your sterile workflow requirements with gamma-irradiated packaging, effectively eliminating preparation overhead. The filter maintains 4.35psi bubble point reliability for consistent performance. Your critical samples benefit from polyethersulfone's documented rapid throughput, combined with 116psi structural integrity margins. Each 100-filter package delivers reproducible clarification supporting your validated analytical methods.
