Grade A Glass Fiber Filter Paper 1.6um, 125mm, Nonsterile, 25/Pk SKU: EF19002

Glass Fiber (GF) Filter Paper - EF19002

Processing samples with high suspended solids concentrations requires a filter medium engineered for particle loading capacity, not just surface retention. Chemically inert borosilicate glass resists degradation across the full pH range, maintaining fiber integrity through acid and alkaline sample matrices. Rigorous quality control at every production stage ensures physical properties align with published grade specifications before distribution.

Key Filter Paper Characteristics

• Binderless glass fiber matrix eliminates organic extractables that would interfere with downstream chromatographic or spectroscopic determinations.
• Nominal retention of 1.6um provides the particle size cutoff appropriate for the analytical or preparative separation method.
• Binderless glass fiber construction delivers ultra-low blank values for gravimetric, thermal, and trace analytical methods requiring clean filter backgrounds.
• Chemically inert glass composition withstands acids, bases, and organic solvents across the full pH range without fiber degradation.
• Randomly oriented glass microfibers create a depth structure that captures particles throughout the matrix, not just at the surface.

If your laboratory runs standardized filtration protocols, the lot-level consistency of this filter paper protects your method reproducibility. In response, 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.

• Water Quality Monitoring - Collects suspended solids from environmental water samples for regulatory compliance and watershed assessment.
• 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.
• 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.
• Turbid Sample Processing - High loading capacity filters heavily particulate environmental and industrial samples without premature clogging.
