Featuring binderless borosilicate glass microfiber technology delivering fine porosity with fast flow rates and 1.2µm particle retention for demanding analytical applications. 100% borosilicate glass construction without binders or strengthening agents ensures chemically inert filtration with exceptional loading capacity. Primarily optimized for RIA procedures, lymphocyte harvesting, and air monitoring applications requiring high-purity depth filtration performance.
Key Glass Microfiber Membrane Characteristics
- Binderless 100% borosilicate glass construction eliminates extractable contaminants for ultra-pure analytical results
- 1.2 micrometer particle retention with fast flow rate characteristics accelerates processing of high-volume samples
- Smooth, uniform fiber matrix permits high flow rates while retaining exceptionally small particles with superior load capacity
- Depth filtration matrix traps particulate within random fiber structure throughout filter thickness for enhanced efficiency
- Thermal stability up to 550°C (1022°F) enables high-temperature applications and incineration analysis
Key Construction Characteristics
- Hydrophobic surface chemistry optimized for non-aqueous solvents and air filtration applications
- 50 grams per square meter basis weight provides optimal balance of strength and porosity
- 42.5mm diameter precision-cut circles accommodate standard filter holders and analytical equipment
- Complex void space structure develops superior efficiency ratings through controlled fiber overlap patterns
- Inert glass matrix ideal for sediment entrapment and subsequent analysis without interference from organic binders
LE-C4250 filters deliver exceptional performance for radioimmuno assay applications and gravimetric determination of airborne particulate, maximizing analytical precision through contamination-free sample preparation. High flow rate characteristics make these filters ideal for single and multi-process removal of sediment and coarse particulate, while serving as superior pre-filtration media prior to membrane filtration. The chemically inert borosilicate matrix ensures reliable results across diverse analytical protocols requiring ultra-pure, binder-free filtration performance.
