Polyethersulfone (PES) Syringe Filters - SPEC18101

Life science laboratories require reliable clarification solutions for protein samples and cell culture reagents, where sample integrity remains paramount. Polyethersulfone membrane technology in SPEC18101 delivers exceptional 0.45µm particle removal with minimal biomolecule interaction, ensuring downstream analytical accuracy. Engineered with polypropylene housing capable of stable operation across diverse solvent systems, each filter maintains structural integrity at 80°C while providing secure double Luer Lock connections for leak-free performance.

Key PES Membrane Characteristics

• Maintains protein concentration through inherently low binding surface chemistry
• Hydrophilic properties allow direct filtration without membrane pre-conditioning steps
• Efficient flow characteristics minimize processing duration for time-sensitive samples
• 0.45µm porosity delivers effective clarification without sterile filtration claims
• Compatible with aqueous buffers, culture media, and mild organic solvent systems

Key Construction Characteristics

• 4.08cm² membrane area accelerates sample throughput for standard laboratory volumes
• Polypropylene construction withstands chemical exposure during extended filtration procedures
• Female-to-male Luer Lock configuration ensures positive syringe engagement under pressure
• Minimizes sample loss with holdup volume remaining below 150µl for valuable reagents

SPEC18101 transforms your clarification protocols with polyethersulfone's characteristic rapid throughput, validated through 29psi bubble point testing. Your laboratory benefits from economical non-sterile packaging while maintaining 116psi burst pressure for reliable performance margins. Bulk 100-pack configuration supports your high-volume analytical requirements with consistent filtration quality.
