Grade A Glass Fiber Filter Paper 1.6um, 42.5mm, Nonsterile, 100/Pk SKU: EF19008

Glass Fiber (GF) Filter Paper - EF19008

High-particulate samples that overwhelm cellulose filter papers demand a depth filter medium with the loading capacity to process the full sample volume. Randomly oriented borosilicate glass microfibers create a depth filtration matrix that captures particles throughout its thickness rather than solely at the surface. Accordingly, rigorous quality control at every production stage ensures physical properties align with published grade specifications before distribution.

Key Filter Paper Characteristics

• Chemically inert glass composition withstands acids, bases, and organic solvents across the full pH range without fiber degradation.
• High void volume between randomly packed fibers sustains rapid flow rates even as accumulated particulate loading increases during filtration.
• Binderless glass fiber matrix eliminates organic extractables that would interfere with downstream chromatographic or spectroscopic determinations.
• Nominal retention ratings defined by fiber diameter and packing density provide consistent particle capture across production lots.
• Hydrophilic glass surface wets spontaneously on contact with aqueous solutions, requiring no pre-conditioning before sample filtration.

When your application makes the filter paper part of the measurement, the ash and weight specifications above define its analytical contribution. For exactly this reason, binderless borosilicate construction eliminates the organic extractables that would compromise your downstream chromatographic or spectroscopic analysis. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

• Stack Emissions Testing - High temperature tolerance supports gravimetric particulate determination from industrial emission source sampling.
• Membrane Prefiltration - Removes coarse debris from turbid samples before downstream membrane analysis to prevent premature blinding.
• Water Quality Monitoring - Collects suspended solids from environmental water samples for regulatory compliance and watershed assessment.
• Chlorophyll Extraction - Concentrates algal cells from water column samples for chlorophyll measurement in aquatic quality assessment.
• Scintillation Counting - Binderless glass fiber provides the chemically clean substrate liquid scintillation counting methods require.
• Turbid Sample Processing - High loading capacity filters heavily particulate environmental and industrial samples without premature clogging.
