Grade A Glass Microfiber Filter, 1.6µm, 90mm, Binderless Borosilicate, EPA Compliant, 100/pk SKU: LE-A9000

Featuring binderless borosilicate glass microfiber technology delivering exceptional 1.6µm particle retention with fast flow rates optimized for protein filtration and radioimmunoassay applications. Pure borosilicate glass construction without binders or strengthening agents provides inert matrix characteristics essential for scintillation counting and gravimetric analysis protocols. Acid-treated and multi-stage deionized water rinsed filters conform to EPA Method 1311¹ requirements, delivering validated performance for toxicity characteristic leaching procedures and environmental waste analysis.

• 100% borosilicate glass microfiber construction eliminates organic contamination from binding agents and maintains chemical purity throughout analytical procedures
• Inherently low barium and zinc borosilicate composition resists acids and bases while delivering consistent performance in corrosive sample environments
• Smooth and uniform glass fiber matrix permits characteristically high flow rates while allowing retention of exceptionally small particles and high loading capacity
• Fine porosity configuration with 1.6µm particle retention ideally suited for radioimmunoassay of weak beta emitters by scintillation counting
• Inert matrix characteristics provide ideal medium for sediment entrapment and analytical counting applications requiring contamination-free sample processing

• High loading capacity design handles concentrated particulate and gelatinous substances while maintaining filtration integrity during extended processing cycles
• Standard 90mm diameter accommodates universal filter holder configurations and laboratory vacuum filtration equipment with precise dimensional stability
• Hydrophobic surface chemistry resists moisture interference during sample preparation while enabling consistent flow characteristics across varied laboratory conditions
• Depth filtration matrix traps particulate within random fiber structure throughout filter thickness, optimizing retention efficiency for complex sample matrices
• Autoclavable glass construction enables pre-cleaning protocols for ultra-trace analysis applications requiring validated sterility and chemical purity standards

LE-A9000 filters achieve fast flow rates essential for high-throughput protein precipitation and cell harvesting applications, accelerating your laboratory processing while maintaining precise 1.6µm retention specifications. Exceptional performance in filtration of precipitated proteins and cells makes these filters ideally suited for radioimmunoassay applications and gravimetric determination of airborne particulates. EPA Method 1311 compliance¹ transforms these filters into validated reference-grade media, providing performance assurance for toxicity characteristic leaching procedures and environmental analysis applications demanding both chemical resistance and certified analytical accuracy.
