Grade 6 Qualitative Filter Paper, Standard, 125mm Circle, 100/Pk SKU: 1006-125

Qualitative Filter Paper - 1006-125

Isolating precipitates from reaction mixtures requires a cellulose matrix that captures solid material completely without premature filter blinding. Standard basis weight specifications provide predictable filter packing density for volumetric displacement calculations in funnel assemblies. Because of this, rigorous quality control at every production stage ensures physical properties align with published grade specifications before distribution.

Key Filter Paper Characteristics

• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
• Standard cellulose construction eliminates chemical treatment steps that could introduce background contamination in sensitive analytical methods.
• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.

Whether your method requires simple clarification or precise gravimetric determination, the documented specifications above define what this paper delivers. Meeting this challenge, economical unit cost at the pack quantities routine laboratories consume keeps your filtration budget aligned with actual throughput demands. 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.

• Pigment Screening - Separates undispersed colorant particles from coating formulations during color development and QC testing.
• Paint and Coatings QC - Removes gels and undispersed pigment from coating samples prior to color measurement and viscosity testing.
• Teaching Laboratory - Provides consistent and economical filtration media for student exercises in analytical and general chemistry.
• Polymer Filtration - Clears particulates from polymer solutions before molecular weight determination by viscometry or GPC.
• Lysate Clarification - Separates cellular debris from crude lysates before downstream chromatographic or electrophoretic analysis.
• Soil Extract Filtration - Clarifies soil slurries for nutrient and pH testing, removing fine particles that interfere with analysis.
