Grade D Glass Microfiber Filter, Binderless Borosilicate, 2.7µm, 35mm, Fast Flow, 100/Pk SKU: LE-D3500

Featuring binderless borosilicate glass microfiber technology delivering coarse porosity with fast flow rates for high-volume laboratory processing applications. A 2.7µm particle retention configuration provides efficient depth filtration while maintaining exceptional flow characteristics optimized for repetitive laboratory filtering protocols. 100% borosilicate construction withstands temperatures up to 500°C, delivering reliable performance across demanding thermal conditions and aggressive chemical environments.

• 100% borosilicate glass microfiber construction without binders or strengthening agents eliminates contamination sources and maintains chemical purity
• Depth filtration matrix traps particulate within random fiber structure throughout the media thickness for superior loading capacity
• Smooth and uniform fiber construction permits characteristically high flow rates while achieving retention of exceptionally small particles
• Temperature resistance up to 500°C enables processing of hot solutions and thermal analytical protocols
• Irregular fiber structure with depth retention properties captures different particle sizes both on surface and within internal matrix

• Well suited for higher volume and repetitive laboratory filtering with consistent performance across extended processing cycles
• Ideal for use as a general pre-filter to extend primary filter life by removing coarse particulates upstream
• Higher loading capacity than filter papers prevents premature clogging and maximizes throughput efficiency
• Standard 35mm diameter accommodates universal laboratory filtration equipment and standard filter holder configurations
• Binderless construction provides high purity for analytical and gravimetric analyses without organic contamination interference

LE-D3500 filters achieve exceptional processing speeds through fast flow rate characteristics that accelerate your laboratory workflows while maintaining reliable particle retention. Outstanding combination of fast flow rates with high load capacity maximizes your filtration efficiency when processing challenging samples containing high particulate loads. Frequently used with finer Grade F filters for sequential filtration protocols, these versatile depth filters optimize your pre-treatment processes for downstream analytical determinations requiring ultra-clean sample preparation.
