Grade B Glass Fiber Filter Paper 1.0um, 125mm, Nonsterile, 10/Pk SKU: EF19017

Glass Fiber (GF) Filter Paper - EF19017

Vacuum filtration of turbid environmental samples requires a depth filter that maintains flow rates through heavy particulate loads without premature blinding. Randomly oriented borosilicate glass microfibers create a depth filtration matrix that captures particles throughout its thickness rather than solely at the surface. Altogether, quality-controlled production produces filter paper with the documented consistency that reproducible analytical and preparative methods demand.

Key Filter Paper Characteristics

• High void volume within the randomly oriented fiber matrix sustains flow rates through heavy particulate loads that would blind surface-capture filters.
• Nominal retention ratings defined by fiber diameter and packing density provide consistent particle capture across production lots.
• Binderless glass fiber matrix eliminates organic extractables that would interfere with downstream chromatographic or spectroscopic determinations.
• Compatible with standard glass and plastic filter holders across all laboratory-standard disc diameters for vacuum and gravity filtration applications.
• Randomly oriented glass microfibers create a depth structure that captures particles throughout the matrix, not just at the surface.

Reporting filtration parameters alongside your analytical results demands documented grade, retention, and lot traceability for reviewer confidence. To meet this need, thermal stability exceeding 500 degrees C supports the ignition step your gravimetric method requires without introducing filter decomposition artifacts. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

• Gravimetric Air Monitoring - Thermal stability supports ignition-based mass determination of collected airborne particulate samples.
• Membrane Prefiltration - Removes coarse debris from turbid samples before downstream membrane analysis to prevent premature blinding.
• Biological Clarification - Clears cell culture harvests and biological lysates of particulate debris before chromatographic purification.
• Scintillation Counting - Binderless glass fiber provides the chemically clean substrate liquid scintillation counting methods require.
• Suspended Solids Analysis - Captures particulates from water and wastewater samples for gravimetric TSS determination by standard methods.
• Stack Emissions Testing - High temperature tolerance supports gravimetric particulate determination from industrial emission source sampling.
