Grade D Glass Fiber Filter Paper 2.7 um, 125mm, Nonsterile, 10/Pk SKU: EF19049

Glass Fiber (GF) Filter Paper - EF19049

Vacuum filtration of turbid environmental samples requires a depth filter that maintains flow rates through heavy particulate loads without premature blinding. High void volume between randomly packed glass fibers sustains rapid flow rates even as particulate loading accumulates during filtration. Taken together, controlled manufacturing delivers the documented retention, flow rate, and physical consistency that analytical and preparative filtration methods require.

Key Filter Paper Characteristics

• Rated at 2.7um particle retention, the fiber matrix provides a defined cutoff for consistent separation across analytical batches.
• Hydrophilic glass fiber wets spontaneously on contact with aqueous solutions, eliminating pre-wetting steps required by hydrophobic filter media.
• Thermal stability exceeding 500 degrees C supports ignition-based gravimetric methods without filter decomposition or residue artifacts.
• Borosilicate glass microfiber depth structure provides high particle loading capacity with flow rates significantly faster than cellulose papers of equivalent retention.
• Pure borosilicate glass provides ultra-low blank values for trace analytical methods sensitive to organic or inorganic background contamination.

Maintaining accreditation requires documented traceability at every step, and the grade specifications above support your audit readiness. Here, rapid flow rates through the glass microfiber matrix reduce the processing time your high-volume filtration workflows demand. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

• Membrane Prefiltration - Removes coarse debris from turbid samples before downstream membrane analysis to prevent premature blinding.
• Suspended Solids Analysis - Captures particulates from water and wastewater samples for gravimetric TSS determination by standard methods.
• Water Quality Monitoring - Collects suspended solids from environmental water samples for regulatory compliance and watershed assessment.
• Protein Precipitation - Captures precipitated proteins from biological fluids for downstream immunoassay and biochemical characterization.
• Biological Clarification - Clears cell culture harvests and biological lysates of particulate debris before chromatographic purification.
• Radioimmunoassay Harvesting - Binderless construction eliminates chemical interference during harvesting of bound radioactive tracers.
