Polyethersulfone (PES) Syringe Filters - SPEC18103

Research laboratories frequently encounter samples containing large aggregates and debris that compromise downstream analytical precision and damage expensive instrumentation. SPEC18103 addresses these challenges with 3.0µm polyethersulfone filtration technology, removing coarse particulates while maintaining exceptional flow rates for time-critical protocols. Engineered polypropylene housing withstands diverse chemical environments at 80°C, complemented by dual Luer Lock connections ensuring leak-free operation under 72.5psi working pressure.

Key PES Membrane Characteristics

• 3.0µm pore dimensions effectively capture large particles and cellular aggregates
• Reduces time requirements through superior flow dynamics inherent to polyethersulfone
• Low affinity for proteins maintains sample composition during clarification procedures
• Compatible with biological buffers, culture reagents, and standard laboratory solvents
• Hydrophilic properties eliminate alcohol pre-treatment for immediate aqueous filtration

Key Construction Characteristics

• Preserves valuable samples with dead volume remaining under 150µl throughout filtration
• Maintains compatibility with standard syringes through universal Luer Lock interfaces
• 4.08cm² active surface area accommodates routine volumes between 10-100ml effectively
• Polypropylene housing provides stable operation across pH ranges and temperature variations

SPEC18103 enhances your laboratory economics through cost-effective non-sterile packaging while delivering 116psi operational confidence for challenging samples. Your filtration protocols achieve consistent results with 4.35psi bubble point verification (at 25°C with water as the wetting agent), ensuring membrane integrity. Bulk packaging in 100-unit quantities supports your high-volume analytical demands with reliable polyethersulfone performance.

Hydrophilic

• Bioreactor Harvest Clarification - Separates microbial cells and protein aggregates from fermentation media, protecting downstream chromatography columns
• Tissue Homogenate Processing - Removes cellular debris, connective tissue fragments, and large particulates before protein extraction and analysis
• Laboratory Reagent Clarification - Removes particulates from freshly prepared buffers, media, and solutions, preventing HPLC and instrument damage
• Food Sample Preparation - Eliminates suspended solids, pulp, and debris from beverage and liquid food samples before microbiological testing
• Industrial Quality Control - Processes manufacturing samples containing visible particles, aggregates, and contaminants for analytical testing
• Prefiltration Protection - Extends expensive 0.22µm and 0.45µm membrane service life by removing coarse particles in high-volume applications
