Grade A Glass Fiber Filter Paper 1.6um, 50mm, Nonsterile, 100/Pk SKU: EF19011

Glass Fiber (GF) Filter Paper - EF19011

Liquid scintillation counting and radioimmunoassay procedures need a binderless glass fiber substrate that introduces no chemical interference to sensitive detection methods. Randomly oriented borosilicate glass microfibers create a depth filtration matrix that captures particles throughout its thickness rather than solely at the surface. Ultimately, each sheet reflects production standards where fiber density, thickness, and retention characteristics are verified before lot release.

Key Filter Paper Characteristics

• Pure borosilicate glass construction eliminates organic extractables that could interfere with downstream chromatographic or spectroscopic analysis.
• Borosilicate glass microfiber depth structure provides high particle loading capacity with flow rates significantly faster than cellulose papers of equivalent retention.
• Basis weight of 53g/m² indicates the fiber mass per unit area that controls retention, flow rate, and mechanical strength.
• Inorganic glass matrix withstands temperatures exceeding 500 degrees C, supporting ignition-based gravimetric methods without filter decomposition.
• Binderless glass fiber construction delivers ultra-low blank values for gravimetric, thermal, and trace analytical methods requiring clean filter backgrounds.

Reporting filtration parameters alongside your analytical results demands documented grade, retention, and lot traceability for reviewer confidence. To meet this need, depth filtration architecture gives you the particle loading capacity to process turbid samples that would blind cellulose papers or surface-capture membranes. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

• Turbid Sample Processing - High loading capacity filters heavily particulate environmental and industrial samples without premature clogging.
• Biological Clarification - Clears cell culture harvests and biological lysates of particulate debris before chromatographic purification.
• Protein Precipitation - Captures precipitated proteins from biological fluids for downstream immunoassay and biochemical characterization.
• Stack Emissions Testing - High temperature tolerance supports gravimetric particulate determination from industrial emission source sampling.
• Gravimetric Air Monitoring - Thermal stability supports ignition-based mass determination of collected airborne particulate samples.
• Membrane Prefiltration - Removes coarse debris from turbid samples before downstream membrane analysis to prevent premature blinding.
