PES Syringe Filters, 5.0um, 20mm, Threaded Double Luer Lock, ABS Housing, Nonsterile, 100/Pk SKU: SPEC18113

Polyethersulfone PES Syringe Filters - SPEC18113

Featuring hydrophilic polyethersulfone membrane technology with 5.0µm pore size for gross particle filtration and primary clarification applications. Laboratory professionals achieve fast flow rates characteristic of PES membranes while protecting downstream filtration systems from large particulates. ABS housing construction combined with double Luer Lock connections ensures chemical resistance and secure operation at pressures up to 72.5psi across diverse biological sample preparation workflows.

Key PES Membrane Characteristics

• Naturally hydrophilic membrane provides immediate wettability for aqueous biological solutions without pre-treatment
• Low protein binding properties minimize sample loss, even with large pore size prefiltration applications
• 5.0µm pore size removes gross particulates and debris, protecting expensive downstream 0.45µm or 0.22µm filters
• Fast flow rates accelerate sample processing compared to other membrane materials at similar pore sizes
• Excellent compatibility with cell culture media, buffers, and biological samples in life science applications

Key Construction Characteristics

• ABS housing material provides chemical resistance and structural stability at temperatures up to 80°C
• Double Luer Lock design featuring female inlet and male outlet prevents disconnection during pressurized filtration
• Low holdup volume (<100µl typical for 20mm format) minimizes loss of valuable biological samples
• 3.1cm² effective filtration area delivers adequate flow rates for processing heavily particulate samples

SPEC18113 filters optimize your laboratory efficiency through superior PES flow rates combined with effective gross particle removal backed by a 2.9psi bubble point. Non-sterile packaging reduces costs for routine applications while the 116psi burst pressure provides a substantial safety margin for confident operation. Your biological workflows benefit from the proven 20mm format, delivering reliable clarification performance with minimal sample loss.

Hydrophilic

• Gross particle removal from cell culture - Clarifies harvest samples containing cell debris before fine filtration
• Protection of sterile filters - Extends the lifespan of expensive 0.22µm filters by removing large contaminants first
• Serum prefiltration - Removes aggregates and precipitates from serum samples before sterile filtration steps
• Biological buffer clarification - Fast processing of buffers containing visible particles or precipitates
• Environmental sample preparation - Clarifies turbid water samples for subsequent microbiological analysis
• Protein solution prefiltration - Low-binding membrane preserves protein concentration during clarification
