Key Glass Microfiber Membrane Characteristics

• Binderless borosilicate glass construction eliminates organic contamination and maintains analytical purity
• Smooth and uniform fiber matrix permits characteristically high flow rates while retaining exceptionally small particles
• DOP efficiency testing confirms 99.98% filtration performance for aerosol particle retention
• Depth filtration captures particles on the surface and traps them within the random fiber matrix structure
• High loading capacity excels in applications involving high concentrations of particulate or gelatinous substances

Key Construction Characteristics

• Temperature resistance up to 500°C maintains structural integrity during high-heat analytical procedures
• Standard 70mm diameter accommodates widespread filter holder configurations and laboratory equipment requirements
• Inert glass matrix provides ideal medium for sediment entrapment and subsequent analysis without sample contamination
• Chemical inertness due to binder-free construction eliminates extractables for gravimetric and analytical applications
• Fast flow rates enable rapid processing while maintaining fine particle retention capabilities

LE-E7000 filters achieve superior performance in water quality testing, environmental monitoring, and laboratory pre-filtration applications where cost-effectiveness meets analytical precision. Excellent pre-filtration capabilities protect downstream membrane filters by capturing larger particles and high particulate loads, extending operational life while maintaining system efficiency. Validated DOP efficiency testing¹ transforms these depth filters into reliable analytical tools, delivering consistent 1.5µm retention performance for your critical sample preparation and environmental analysis protocols requiring both economic value and proven filtration reliability.
