Grade 201 Cellulose Filter Paper, 32 cm Circle, 100/Pk SKU: 5201-320

Qualitative Filter Paper - 5201-320

From student teaching labs to production QC departments, qualitative filter paper remains the workhorse for routine particle separation. Natural cellulose wettability eliminates the pre-wetting step required by hydrophobic membranes in aqueous sample filtration. Together, certificate of conformance documentation accompanies each lot, providing traceability for quality systems and regulatory audit requirements.

Key Filter Paper Characteristics

• Strengthening treatment preserves paper structure through extended filtration runs where continuous wetting would weaken standard grades.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Basis weight of 75g/m² indicates the fiber mass per unit area that controls retention, flow rate, and wet strength.
• At Medium Fine rated retention, the fiber matrix captures particles above the threshold while allowing smaller materials to pass through.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.

Whether your method requires simple clarification or precise gravimetric determination, the documented specifications above define what this paper delivers. Standard cellulose chemistry eliminates the need for specialized disposal procedures your general laboratory filtration generates. 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.
