Grade F Glass Microfiber Filter, 0.7µm, 25mm, Binderless Borosilicate, TCLP Compliant, 100/Pk SKU: LE-F2500

Featuring binderless borosilicate glass microfiber technology delivering exceptional 0.7µm particle retention for critical biochemical and environmental analysis applications. Fine porosity configuration provides medium flow rate characteristics while maintaining superior loading capacity for diluted aqueous solutions containing strong oxidizing, acidic, or alkaline components. Pure borosilicate glass structure enables EPA Method TCLP 1311¹ compliance, transforming these filters into validated reference-grade media for toxicity characteristic leaching procedures and environmental monitoring protocols.

Key Glass Microfiber Membrane Characteristics

• Binderless borosilicate glass microfiber construction eliminates organic contamination and maintains analytical purity throughout filtration processes
• 0.7µm particle retention efficiently captures fine precipitated proteins, including immunoglobulins and cellular debris in biochemical applications
• Rapid flow rate with extremely high loading capacity accelerates processing compared to membrane filters with comparable retention values
• Autoclavable glass construction enables pre-sterilization protocols for sterile filtration and cell culture applications
• Hydrophobic surface chemistry resists moisture interference during sample preparation and analytical procedures

Key Construction Characteristics

• 25mm diameter accommodates standard filtration equipment and universal filter holder configurations for laboratory versatility
• Depth filtration matrix traps particulate within random fiber structure providing exceptional retention efficiency and high dirt-holding capacity
• Frequently used with Grade D filters for sequential filtration of challenging solutions prior to laser spectroscopy and HPLC analysis
• 100% borosilicate glass composition delivers chemical resistance to strong acids, bases, and organic solvents in demanding laboratory environments
• Standard 100-pack configuration provides consistent supply for high-volume analytical laboratories and quality control protocols

Grade F filters achieve outstanding performance in critical applications including clarification of protein solutions and filtering samples prior to HPLC, maximizing your analytical accuracy even with complex biochemical matrices. Very effective in filtering finely precipitated proteins and can be used in conjunction with prefilters for successful clarification of difficult solutions. EPA TCLP Method 1311¹ specification compliance transforms these filters into validated environmental testing media, providing performance assurance for your critical toxicity characteristic leaching procedures and regulatory compliance applications requiring both precision particle retention and certified analytical reliability.
