PES Syringe Filters, 3.0um, 20mm, Threaded Double Luer Lock, ABS Housing, Sterile, 100/Pk SKU: SPEC18117

Polyethersulfone Syringe Filters - SPEC18117

Laboratory samples containing cellular debris, aggregates, and large particulates frequently clog expensive downstream filters and compromise analytical instrument performance. Hydrophilic PES membranes with 3.0µm pore size provide effective prefiltration solutions, removing problematic particles while preserving dissolved components and biomolecules. Engineered with ABS housing construction rated for 116psi burst pressure, ensuring reliable performance throughout demanding filtration protocols requiring sterile, contamination-free processing.

Key Polyethersulfone Membrane Characteristics

• Broad chemical compatibility resists degradation from buffers, culture media, and aqueous biological preparations
• Natural hydrophilicity enables immediate use without pre-wetting, reducing preparation time significantly
• Low protein affinity maintains biomolecule concentrations during clarification and prefiltration procedures
• Coarse 3.0µm porosity effectively captures cells, debris, and aggregates while allowing smaller particles through
• Consistent pore distribution verified by 4.35psi bubble point testing ensures reproducible filtration results

Key Construction Characteristics

• Acrylonitrile butadiene styrene housing maintains structural integrity at temperatures reaching 80°C
• Threaded double luer lock design prevents disconnection under 72.5psi maximum operating pressure
• Compact 20mm diameter suits small to medium volume applications requiring 1-50ml processing capacity
• Gamma-sterilized packaging eliminates contamination risks, providing immediate sterile filtration capability

SPEC18117 filters solve your prefiltration challenges through reliable 3.0µm particle retention combined with sterile packaging convenience. Your research protocols benefit from operational confidence at 72.5psi working pressure while the compact 20mm format minimizes sample loss in valuable or limited-volume applications.
