Grade C Glass Fiber Filter Paper 1.2um, 125mm, Nonsterile, 25/Pk SKU: EF19032

Glass Fiber (GF) Filter Paper - EF19032

High-particulate samples that overwhelm cellulose filter papers demand a depth filter medium with the loading capacity to process the full sample volume. Thermal stability exceeding 500 degrees C allows direct ignition of the loaded filter for gravimetric suspended solids determinations. In turn, documented grade specifications provide laboratories with the technical data needed to select appropriate papers without preliminary testing.

Key Filter Paper Characteristics

• Pure borosilicate glass provides ultra-low blank values for trace analytical methods sensitive to organic or inorganic background contamination.
• High void volume within the randomly oriented fiber matrix sustains flow rates through heavy particulate loads that would blind surface-capture filters.
• Borosilicate glass microfiber construction provides depth filtration with loading capacity far exceeding cellulose papers of equivalent retention.
• Borosilicate glass microfiber depth structure provides high particle loading capacity with flow rates significantly faster than cellulose papers of equivalent retention.
• Chemically inert borosilicate composition resists 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. Under these conditions, high void volume within the fiber matrix extends the sample volume you can process before flow restriction requires a filter change. 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.
• Radioimmunoassay Harvesting - Binderless construction eliminates chemical interference during harvesting of bound radioactive tracers.
• Air Particulate Sampling - Captures airborne particulates by vacuum filtration for gravimetric mass determination and subsequent analysis.
• Chlorophyll Extraction - Concentrates algal cells from water column samples for chlorophyll measurement in aquatic quality assessment.
• Turbid Sample Processing - High loading capacity filters heavily particulate environmental and industrial samples without premature clogging.
