Grade D Glass Fiber Filter Paper 2.7 um, 24mm, Nonsterile, 50/Pk SKU: EF19053

Glass Fiber (GF) Filter Paper - EF19053

Liquid scintillation counting and radioimmunoassay procedures need a binderless glass fiber substrate that introduces no chemical interference to sensitive detection methods. Inorganic glass composition produces ultra-low extractable levels suitable for trace analytical methods sensitive to organic background interference. For this reason, standardized manufacturing protocols produce papers with retention and flow characteristics that remain constant from the first batch to the last.

Key Filter Paper Characteristics

• Chemically inert glass composition withstands 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.
• Binderless glass fiber matrix eliminates organic extractables that would interfere with downstream chromatographic or spectroscopic determinations.
• Thermal stability exceeding 500 degrees C supports ignition-based gravimetric methods without filter decomposition or residue artifacts.
• Compatible with standard glass and plastic filter holders across all laboratory-standard disc diameters for vacuum and gravity filtration applications.

If your laboratory supports multiple research groups with varying filtration needs, this paper's broad applicability simplifies your procurement process. To that end, 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.

• Protein Precipitation - Captures precipitated proteins from biological fluids for downstream immunoassay and biochemical characterization.
• Water Quality Monitoring - Collects suspended solids from environmental water samples for regulatory compliance and watershed assessment.
• Stack Emissions Testing - High temperature tolerance supports gravimetric particulate determination from industrial emission source sampling.
• 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.
• Gravimetric Air Monitoring - Thermal stability supports ignition-based mass determination of collected airborne particulate samples.
