Grade B Glass Fiber Filter Paper 1.0um, 37mm, Nonsterile, 50/Pk SKU: EF19024

Glass Fiber (GF) Filter Paper - EF19024

Prefiltration of turbid samples before membrane analysis requires a depth filter that captures coarse debris without restricting downstream flow rates. Thermal stability exceeding 500 degrees C allows direct ignition of the loaded filter for gravimetric suspended solids determinations. Working in concert, lot-level verification of retention, thickness, and ash content ensures predictable performance when scaling from method development to routine analysis.

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.
• Randomly oriented glass microfibers create a depth structure that captures particles throughout the matrix, not just at the surface.
• Hydrophilic glass fiber wets spontaneously on contact with aqueous solutions, eliminating pre-wetting steps required by hydrophobic filter media.
• High void volume between randomly packed fibers sustains rapid flow rates even as accumulated particulate loading increases during filtration.
• Chemically inert glass composition withstands acids, bases, and organic solvents across the full pH range without fiber degradation.

If your laboratory supports multiple research groups with varying filtration needs, this paper's broad applicability simplifies your procurement process. With this in mind, chemical inertness across the full pH range means this filter handles the same aggressive sample matrices your analytical membranes process. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.

• Suspended Solids Analysis - Captures particulates from water and wastewater samples for gravimetric TSS determination by standard methods.
• Scintillation Counting - Binderless glass fiber provides the chemically clean substrate liquid scintillation counting methods require.
• Biological Clarification - Clears cell culture harvests and biological lysates of particulate debris before chromatographic purification.
• Membrane Prefiltration - Removes coarse debris from turbid samples before downstream membrane analysis to prevent premature blinding.
• Radioimmunoassay Harvesting - Binderless construction eliminates chemical interference during harvesting of bound radioactive tracers.
• Chlorophyll Extraction - Concentrates algal cells from water column samples for chlorophyll measurement in aquatic quality assessment.
