Grade D Glass Microfiber Filter, Binderless Borosilicate, 2.7µm, 55mm, Fast Flow, 100/Pk SKU: LE-D5500

Featuring binderless borosilicate glass microfiber technology delivering exceptional depth filtration performance for high-volume laboratory applications. Coarse porosity with fast flow rate and 2.7µm particle retention makes these filters well suited for higher volume and repetitive laboratory filtering. Pure borosilicate construction without binders provides temperature resistance up to 500°C, enabling versatile processing of demanding analytical samples requiring thermal stability and chemical purity.

Key Glass Microfiber Membrane Characteristics

• Binderless borosilicate glass microfiber construction eliminates organic contamination from binders or strengthening agents
• 2.7µm coarse porosity enables fast flow rates while maintaining reliable particle retention for efficient sample processing
• Outstanding thermal stability withstands continuous operation up to 500°C without degradation or dimensional change
• Depth filtration matrix traps particulates within the random fiber structure, with efficiency characteristic of complex pore development as fibers overlap
• Higher loading capacity than conventional filter papers prevents premature clogging during extended filtration cycles

Key Construction Characteristics

• 120 grams per square meter basis weight provides robust mechanical strength for reliable handling and installation
• Fast flow rate configuration optimizes throughput for higher volume and repetitive laboratory filtering applications
• Chemical resistance to most acids, alkalis, and organic solvents ensures durability in aggressive analytical environments
• Functions effectively as a prefilter when used with finer membrane filters to extend primary filter life and reduce costs
• Smooth and uniform fiber construction permits characteristically high flow rates while retaining exceptionally small particles with high load capacity

LE-D5500 filters maximize your analytical efficiency through superior particle loading capacity and fast drainage characteristics, accelerating sample processing even during challenging filtration workflows. These characteristics prove particularly important in applications involving high concentrations of particulate or gelatinous substances. The 55mm diameter accommodates standard laboratory filter holders while delivering consistent performance across diverse analytical protocols requiring reliable depth filtration and thermal stability for precise scientific measurements.
