Key Glass Microfiber Membrane Characteristics

Nano-scale fiber architecture with >85% fibers between 300-1000nm delivers maximum surface area for superior particle capture
Binderless borosilicate glass construction eliminates organic additives and surfactants, ensuring minimal background interference in LC/GC/MS analysis
Exceptional 0.5µm particle retention combines membrane-like precision with >20x loading capacity of equivalent MCE or cellulose nitrate filters
Hydrophobic surface chemistry resists moisture interference while providing excellent protein binding affinity for separation and recovery applications
Chemically inert glass composition withstands aggressive solvents with ultra-low extractables for trace analysis protocols

Key Construction Characteristics

Smooth glass fiber consolidation creates highly retentive filter matrix with consistent thickness and mass specifications
Outstanding thermal stability enables continuous operation to 500°C, far exceeding polymeric membrane limitations
Universal 21mm diameter accommodates standard filter holders and analytical equipment configurations
Minimal back pressure compared to surface membranes accelerates sample processing while maintaining filtration integrity
Autoclavable construction supports pre-cleaning protocols and sterile handling requirements for sensitive applications

Grade A-83 filters achieve remarkable flow rates with nearly non-existent back pressure, dramatically accelerating your analytical cycles compared to conventional membrane technologies. Superior chemical resistance to all acids except hydrofluoric acid maximizes compatibility with aggressive sample matrices and cleaning protocols. Independent laboratory verification using advanced SEM quantification confirms true nano-scale fiber characteristics, providing validated performance assurance for your most critical pre-filtration, clarification, and analytical separation applications demanding both exceptional retention and ultra-high throughput capabilities.
