Grade B Glass Fiber Filter Paper 1.0um, 110mm, Nonsterile, 10/Pk SKU: EF19016

Glass Fiber (GF) Filter Paper - EF19016

Analytical methods specifying glass microfiber collection media require filters manufactured to consistent retention and purity specifications across production lots. Chemically inert borosilicate glass resists degradation across the full pH range, maintaining fiber integrity through acid and alkaline sample matrices. To this end, controlled manufacturing delivers the documented retention, flow rate, and physical consistency that analytical and preparative filtration methods require.

Key Filter Paper Characteristics

• 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.
• High void volume within the randomly oriented fiber matrix sustains flow rates through heavy particulate loads that would blind surface-capture filters.
• Compatible with standard glass and plastic filter holders across all laboratory-standard disc diameters for vacuum and gravity filtration applications.
• Borosilicate glass microfiber construction provides depth filtration with loading capacity far exceeding cellulose papers of equivalent retention.

Your sample preparation workflow benefits from a filter paper whose performance is defined, documented, and consistent from one purchase to the next. To that end, high void volume within the fiber matrix extends the sample volume you can process before flow restriction requires a filter change. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.

• Membrane Prefiltration - Removes coarse debris from turbid samples before downstream membrane analysis to prevent premature blinding.
• Radioimmunoassay Harvesting - Binderless construction eliminates chemical interference during harvesting of bound radioactive tracers.
• Turbid Sample Processing - High loading capacity filters heavily particulate environmental and industrial samples without premature clogging.
• Air Particulate Sampling - Captures airborne particulates by vacuum filtration for gravimetric mass determination and subsequent analysis.
• Suspended Solids Analysis - Captures particulates from water and wastewater samples for gravimetric TSS determination by standard methods.
• Stack Emissions Testing - High temperature tolerance supports gravimetric particulate determination from industrial emission source sampling.
