Grade A Glass Fiber Filter Paper 1.6um, 150mm, Nonsterile, 25/Pk SKU: EF19019

Glass Fiber (GF) Filter Paper - EF19019

Processing samples with high suspended solids concentrations requires a filter medium engineered for particle loading capacity, not just surface retention. Thick fiber matrix provides high dirt-holding capacity that extends filter service life when processing turbid or heavily particulate samples. Documented grade specifications provide laboratories with the technical data needed to select appropriate papers without preliminary testing.

Key Filter Paper Characteristics

• Nominal retention ratings defined by fiber diameter and packing density provide consistent particle capture across production lots.
• Chemically inert glass composition withstands acids, bases, and organic solvents across the full pH range without fiber degradation.
• Hydrophilic glass surface wets spontaneously on contact with aqueous solutions, requiring no pre-conditioning before sample filtration.
• High void volume between randomly packed fibers sustains rapid flow rates even as accumulated particulate loading increases during filtration.
• Borosilicate glass microfiber depth structure provides high particle loading capacity with flow rates significantly faster than cellulose papers of equivalent retention.

Whether your method requires simple clarification or precise gravimetric determination, the documented specifications above define what this paper delivers. Addressing this directly, multiple retention grades from 0.7 to 2.7 micrometers let you select the particle capture threshold each of your methods specifies. 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.

• Radioimmunoassay Harvesting - Binderless construction eliminates chemical interference during harvesting of bound radioactive tracers.
• Stack Emissions Testing - High temperature tolerance supports gravimetric particulate determination from industrial emission source sampling.
• Scintillation Counting - Binderless glass fiber provides the chemically clean substrate liquid scintillation counting methods require.
• Chlorophyll Extraction - Concentrates algal cells from water column samples for chlorophyll measurement in aquatic quality assessment.
• Protein Precipitation - Captures precipitated proteins from biological fluids for downstream immunoassay and biochemical characterization.
• Membrane Prefiltration - Removes coarse debris from turbid samples before downstream membrane analysis to prevent premature blinding.
