Grade 202 Cellulose Filter Paper, 40 cm Circle, 100/Pk SKU: 5202-400

Qualitative Filter Paper - 5202-400

Isolating precipitates from reaction mixtures requires a cellulose matrix that captures solid material completely without premature filter blinding. Uniform pore distribution across the sheet area ensures consistent particle capture from center to edge during gravity filtration. Taken together, consistent physical properties across the full sheet area support uniform filtration results in both gravity and vacuum applications.

Key Filter Paper Characteristics

• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Basis weight of 82g/m² indicates the fiber mass per unit area that controls retention, flow rate, and wet strength.
• Unmodified cellulose surface provides natural hydrophilic properties for rapid wetting in aqueous filtration applications.
• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.

If your teaching or research laboratory processes high volumes of routine samples, the documented flow rates above translate directly to throughput. For this application, standard qualitative construction integrates into your existing funnel hardware, requiring no new equipment investment for reliable results. 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.
