Grade A Glass Microfiber Filter, 1.6µm, 55mm, Binderless Borosilicate, Fast Flow, 100/Pk SKU: LE-A5500

Featuring binderless borosilicate glass microfiber technology delivering 1.6µm particle retention with fast flow rates for demanding biochemical and environmental analysis applications. 100% borosilicate glass construction without binders or strengthening agents provides exceptional purity for protein precipitation, cell harvesting, and radioimmunoassay applications. Acid treated and multi-stage deionized water rinsed to conform to EPA Method 1311¹ standards ensures validated performance for toxicity characteristic leaching procedures and environmental compliance protocols.

Key Glass Microfiber Membrane Characteristics

100% borosilicate glass composition free of binders eliminates organic contamination interference in trace analysis applications
Smooth and uniform fiber construction permits characteristically high flow rates while retaining exceptionally small particles
Depth filtration matrix traps particulate within random fiber structure, with efficiency characteristic of complex void space development
Inherently low Barium and Zinc borosilicate glass resistant to acids and bases maximizes chemical compatibility
High load capacity characteristics particularly important for high concentrations of particulate or gelatinous substances

Key Construction Characteristics

55mm diameter accommodates standard filtration equipment and universal filter holder configurations
Frequently used for filtration of precipitated proteins and cells in biochemical research applications
Ideally suited for radioimmunoassay of weak beta emitters by scintillation counting and gravimetric determination of airborne particulate
Hydrophobic surface chemistry resists moisture interference during analytical procedures
Nonsterile construction ready for immediate use in routine analytical protocols

LE-A5500 filters deliver outstanding chemical resistance to acids and bases while maintaining structural integrity under demanding analytical conditions. Ideal medium to entrap sediment for further analysis and counting due to the inert matrix, these filters accelerate your sample processing workflows in protein biochemistry, environmental monitoring, and waste characterization applications. Recommended for use in U.S. EPA Method 1311 "Toxicity Characteristic Leaching Procedure"¹ transforms these filters into validated reference-grade media, providing performance assurance for your critical environmental compliance and waste analysis applications demanding both high purity and proven regulatory acceptance.
