Grade A Glass Fiber Filter Paper 1.6um, 90mm, Nonsterile, 25/Pk SKU: EF19014

Glass Fiber (GF) Filter Paper - EF19014

Air particulate sampling for gravimetric mass determination demands a filter medium with low tare weight variability and thermal stability through weighing procedures. Thick fiber matrix provides high dirt-holding capacity that extends filter service life when processing turbid or heavily particulate samples. Ultimately, lot-level verification of retention, thickness, and ash content ensures predictable performance when scaling from method development to routine analysis.

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.
• Depth filtration captures particles throughout the fiber matrix rather than at the surface, maximizing total loading capacity before flow restriction.
• Pure borosilicate glass provides ultra-low blank values for trace analytical methods sensitive to organic or inorganic background contamination.
• Pure borosilicate glass construction eliminates organic extractables that could interfere with downstream chromatographic or spectroscopic analysis.
• Inorganic glass matrix withstands temperatures exceeding 500 degrees C, supporting ignition-based gravimetric methods without filter decomposition.

If your environmental monitoring program depends on sample comparability to determine trends, the production consistency of this filter paper protects your data validity. In response, thermal stability exceeding 500 degrees C supports the ignition step your gravimetric method requires without introducing filter decomposition artifacts. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

• Gravimetric Air Monitoring - Thermal stability supports ignition-based mass determination of collected airborne particulate samples.
• Scintillation Counting - Binderless glass fiber provides the chemically clean substrate liquid scintillation counting methods require.
• Biological Clarification - Clears cell culture harvests and biological lysates of particulate debris before chromatographic purification.
• 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.
• Membrane Prefiltration - Removes coarse debris from turbid samples before downstream membrane analysis to prevent premature blinding.
