PES Syringe Filters, 3.0um, 20mm, Threaded Double Luer Lock, ABS Housing, Nonsterile, 100/Pk SKU: SPEC18112

Polyethersulfone (PES) Syringe Filters - SPEC18112

Engineered with hydrophilic polyethersulfone membrane technology offering 3.0µm pore size for robust prefiltration and coarse particle removal from biological samples and aqueous solutions. Specialized 20mm diameter design with threaded double luer lock connections ensures secure attachment during high-pressure operations. Durable ABS housing withstands burst pressures up to 116psi while maintaining operational confidence throughout demanding laboratory protocols.

Key Polyethersulfone Membrane Characteristics

• Naturally hydrophilic surface requires no pre-wetting, accelerating workflow efficiency in time-sensitive applications
• Broad chemical compatibility withstands diverse buffer systems, culture media, and aqueous biological preparations
• Coarse 3.0µm retention effectively removes cellular debris, aggregates, and large particulates from sensitive samples
• Minimal protein adsorption preserves biomolecule concentration during clarification and prefiltration procedures
• Rapid flow characteristics optimize processing speeds for medium-volume laboratory applications

Key Construction Characteristics

• Acrylonitrile butadiene styrene housing maintains structural integrity at temperatures up to 80°C
• Threaded double luer lock design prevents disconnection during pressurized filtration operations
• Maximum operating pressure of 72.5psi accommodates standard laboratory syringe applications
• Bubble point verification at 4.35psi confirms consistent membrane pore structure and integrity

SPEC18112 filters optimize your prefiltration workflows with reliable 3.0µm particle retention and exceptional chemical resistance across diverse laboratory applications. Your samples benefit from rapid processing through hydrophilic PES membranes that eliminate pre-wetting steps while maintaining low protein binding throughout filtration.
