Grade A Glass Microfiber Filter, Binderless - 1.6µm, 70mm, High Flow Rate, 100/pk SKU: LE-A7000

Featuring binderless borosilicate glass microfiber technology delivering exceptional particle retention at 1.6µm with characteristically high flow rates for demanding analytical applications. This depth filtration medium utilizes 100% borosilicate glass microfibers manufactured without binders or strengthening agents, creating smooth and uniform fibers that permit high flow rates while retaining exceptionally small particles with superior loading capacity. Frequently used in the filtration of precipitated proteins and cells, these filters are ideally suited for radioimmuno assay of weak beta emitters by scintillation counting and gravimetric determination of airborne particulates.

Key Glass Microfiber Membrane Characteristics

Binderless borosilicate construction eliminates contamination from binders and strengthening agents for ultra-pure analytical results
1.6µm particle retention at 98% efficiency delivers precise separation while maintaining fast flow characteristics
Depth filtration matrix traps particulates within the random fiber structure, with efficiency determined by complex void spaces that develop as fibers overlap
Temperature resistance up to 500°C enables high-temperature processing and incineration protocols for gravimetric analysis
Hydrophobic surface chemistry resists moisture interference while providing excellent wetting properties for aqueous sample processing

Key Construction Characteristics

Standard 70mm diameter accommodates most laboratory filtration equipment and analytical sample preparation protocols
Low resistance to fluid flow combined with high particle-loading capacity maximizes sample throughput in high-volume applications
Fine capillary structure absorbs large quantities of water, enabling spot tests and liquid scintillation counting methods
100 filters per package provide cost-effective supply for routine laboratory operations and quality control testing
High dirt-holding capacity and fast flow rates make these filters ideal for air and liquid filtration, sample clarification, and analytical applications

LE-A7000 filters deliver optimized performance for biochemical applications requiring ultra-pure, binder-free media, accelerating your protein precipitation and cell harvesting protocols while maintaining analytical integrity. These established standard filters excel in gravimetric determination of airborne particulates and are widely used for water and air pollution monitoring applications. Superior pre-filtration performance protects downstream membrane filters while their versatile 1.6µm retention provides reliable clarification across diverse sample matrices, making them indispensable for laboratories demanding consistent analytical results.
