Grade B Glass Fiber Filter Paper 1.0um, 55mm, Nonsterile, 10/Pk SKU: EF19028

Glass Fiber (GF) Filter Paper - EF19028

Prefiltration of turbid samples before membrane analysis requires a depth filter that captures coarse debris without restricting downstream flow rates. Available across multiple retention grades from coarse prefiltration through fine particle capture to match specific analytical method requirements. Taken together, controlled manufacturing delivers the documented retention, flow rate, and physical consistency that analytical and preparative filtration methods require.

Key Filter Paper Characteristics

• Depth filtration captures particles throughout the fiber matrix rather than at the surface, maximizing total loading capacity before flow restriction.
• Compatible with standard glass and plastic filter holders across all laboratory-standard disc diameters for vacuum and gravity filtration applications.
• Chemically inert glass composition withstands acids, bases, and organic solvents across the full pH range without fiber degradation.
• Manufactured to a basis weight of 143g/m², each filter delivers the documented mass consistency that gravimetric methods require.
• Thermal stability exceeding 500 degrees C supports ignition-based gravimetric methods without filter decomposition or residue artifacts.

If you're transitioning from qualitative screening to quantitative gravimetric work, the documented ash content above confirms this paper's suitability. Ultra-low blank values from pure borosilicate glass protect the accuracy of your trace-level environmental and gravimetric determinations. 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.

• Air Particulate Sampling - Captures airborne particulates by vacuum filtration for gravimetric mass determination and subsequent analysis.
• Turbid Sample Processing - High loading capacity filters heavily particulate environmental and industrial samples without premature clogging.
• Radioimmunoassay Harvesting - Binderless construction eliminates chemical interference during harvesting of bound radioactive tracers.
• Scintillation Counting - Binderless glass fiber provides the chemically clean substrate liquid scintillation counting methods require.
• 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.
