Grade C Glass Fiber Filter Paper 1.2um, 42.5mm, Nonsterile, 100/Pk SKU: EF19042

Glass Fiber (GF) Filter Paper - EF19042

Prefiltration of turbid samples before membrane analysis requires a depth filter that captures coarse debris without restricting downstream flow rates. Available across multiple retention grades from coarse prefiltration through fine particle capture to match specific analytical method requirements. Taken together, documented grade specifications provide laboratories with the technical data needed to select appropriate papers without preliminary testing.

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.
• Borosilicate glass microfiber construction provides depth filtration with loading capacity far exceeding cellulose papers of equivalent retention.
• Chemically inert borosilicate composition resists acids, bases, and organic solvents across the full pH range without fiber degradation.
• Binderless glass fiber construction delivers ultra-low blank values for gravimetric, thermal, and trace analytical methods requiring clean filter backgrounds.
• Rated at 1.2um particle retention, the fiber matrix provides a defined cutoff for consistent separation across analytical batches.

If your laboratory supports multiple research groups with varying filtration needs, this paper's broad applicability simplifies your procurement process. Binderless borosilicate construction eliminates the organic extractables that would compromise your downstream chromatographic or spectroscopic analysis. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

• Turbid Sample Processing - High loading capacity filters heavily particulate environmental and industrial samples without premature clogging.
• Membrane Prefiltration - Removes coarse debris from turbid samples before downstream membrane analysis to prevent premature blinding.
• Scintillation Counting - Binderless glass fiber provides the chemically clean substrate liquid scintillation counting methods require.
• Gravimetric Air Monitoring - Thermal stability supports ignition-based mass determination of collected airborne particulate samples.
• 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.
