Grade C Glass Fiber Filter Paper 1.2um, 8 Inch x 10 Inch, Nonsterile, 25/Pk SKU: EF19030

Glass Fiber (GF) Filter Paper - EF19030

Water quality monitoring programs need glass microfiber filters with documented retention specifications that satisfy regulatory method requirements. Chemically inert borosilicate glass resists degradation across the full pH range, maintaining fiber integrity through acid and alkaline sample matrices. As a result, certificate of conformance documentation accompanies each lot, providing traceability for quality systems and regulatory audit requirements.

Key Filter Paper Characteristics

• Pure borosilicate glass provides ultra-low blank values for trace analytical methods sensitive to organic or inorganic background contamination.
• Randomly oriented glass microfibers create a depth structure that captures particles throughout the matrix, not just at the surface.
• Basis weight of 55g/m² indicates the fiber mass per unit area that controls retention, flow rate, and mechanical strength.
• Compatible with standard glass and plastic filter holders across all laboratory-standard disc diameters for vacuum and gravity filtration applications.
• Hydrophilic glass surface wets spontaneously on contact with aqueous solutions, requiring no pre-conditioning before sample filtration.

If your laboratory runs standardized filtration protocols, the lot-level consistency of this filter paper protects your method reproducibility. For applications like these, hydrophilic glass surface eliminates the pre-wetting steps your aqueous filtration protocols would otherwise require before processing begins. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

• Membrane Prefiltration - Removes coarse debris from turbid samples before downstream membrane analysis to prevent premature blinding.
• Stack Emissions Testing - High temperature tolerance supports gravimetric particulate determination from industrial emission source sampling.
• 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.
• Water Quality Monitoring - Collects suspended solids from environmental water samples for regulatory compliance and watershed assessment.
• Air Particulate Sampling - Captures airborne particulates by vacuum filtration for gravimetric mass determination and subsequent analysis.
