Grade D Glass Microfiber Filter, Binderless - 2.7µm, 42.5mm - 100/pk SKU: LE-D4250

Featuring coarse porosity glass microfiber technology delivering exceptional flow rates and high particle loading capacity for demanding laboratory filtration applications. With 2.7µm particle retention and fast flow characteristics, these filters excel in higher volume and repetitive laboratory filtering workflows. Binderless borosilicate glass construction eliminates organic contamination while providing superior chemical inertness for critical analytical procedures requiring validated sample preparation.

Key Glass Microfiber Membrane Characteristics

• Binderless borosilicate glass microfiber construction ensures complete chemical inertness and eliminates organic binder interference
• Coarse porosity design with 2.7µm particle retention optimized for fast flow rates in high-volume applications
• Depth filtration matrix combines fast flow rates with high loading capacity and retention of fine particles extending into the sub-micron range
• Exceptional thermal stability withstands temperatures up to 500°C for gravimetric analysis and high-temperature applications
• Fine capillary structure absorbs significantly larger quantities of water than equivalent cellulose filters for liquid scintillation applications

Key Construction Characteristics

• Low resistance design optimized for applications involving fluid flow and high particle loading capacity requirements
• Depth filter construction traps particulates within the random matrix of smooth, uniform fibers throughout the media thickness
• Inert glass matrix provides ideal medium for sediment entrapment enabling further analysis and particle counting procedures
• 42.5mm diameter accommodates standard laboratory filtration equipment and funnel configurations for versatile installation
• Autoclavable construction enables sterilization protocols for contamination-sensitive analytical applications

LE-D4250 filters are engineered for high-volume and repetitive laboratory filtering while serving as ideal general pre-filters to extend primary membrane filter life. Outstanding flow characteristics make these filters essential for single and multi-process removal of sediment and coarse particulate, commonly used for pre-filtration prior to surface filtration with membrane substrates. Superior performance in air filtration and gravimetric analysis of volatile materials where ignition is involved transforms these filters into versatile analytical tools, providing reliable sample preparation for your most demanding laboratory workflows requiring both exceptional throughput and validated particle retention capabilities.
