Grade F Glass Microfiber Filter, 0.7µm, 150mm, Binderless Borosilicate, 100/Pk SKU: LE-F1500

Featuring binderless borosilicate glass microfiber technology delivering 0.6 µm - 0.8 µm particle retention for precise analytical filtration applications. Fine porosity, medium flow rate, with a 0.7 µm size particle retention optimizes filtration performance while maintaining exceptional chemical resistance to strong oxidizing, acidic, or alkaline components. Pure borosilicate glass composition selected by the US Environmental Protection Agency (EPA) for use in developing the Toxicity Characteristic Leaching Procedure (TCLP) 1311 delivers validated performance for critical environmental compliance applications.

Key Glass Microfiber Membrane Characteristics

100% borosilicate glass microfiber without the use of binders or strengthening agents eliminates contamination from organic compounds
Smooth and uniform fibers permit characteristically high flow rates while allowing retention of exceptionally small particles and high load capacity
Hydrophobic surface chemistry resists moisture interference during aqueous solution processing and biochemical applications
High load capacity characteristics particularly important in applications involving high concentrations of particulate or gelatinous substances
Autoclavable construction enables sterilization protocols for sterile filtration requirements

Key Construction Characteristics

150mm diameter accommodates standard analytical equipment and universal filter holder configurations for laboratory workflows
0.4 mm thickness with 80 g/m² nominal basis weight provides structural integrity during high-volume processing
475°C maximum temperature tolerance withstands thermal processing and high-temperature analytical protocols
Nonsterile packaging with 100 filters per package optimizes laboratory inventory management and cost-effectiveness
Depth filtration matrix traps particulate within random fiber structure maximizing retention efficiency and throughput capacity

LE-F1500 filters excel in two critical areas: established standard for US EPA TCLP Analysis (Method 1311) and biochemistry applications for isolation of extremely fine precipitated proteins (such as IgG) and DNA purification. Suitable for critical applications including enumeration of Salmonella and Pseudomonas Aeroginosa, clarification of protein solutions and filtering samples and solvents prior to HPLC. Outstanding chemical compatibility with strong oxidizing, acidic, or alkaline components prior to laser spectroscopy transforms these filters into versatile analytical media, providing performance assurance for your environmental compliance testing, biochemical purification, and precision analytical applications demanding both regulatory validation and exceptional filtration reliability.
