Grade 2V Qualitative Filter Paper, Pre-Folded, 400mm Circle, 100/Pk SKU: 1202-400

Qualitative Filter Paper - 1202-400

General clarification and sample preparation workflows require a cellulose filter paper with predictable performance across varying sample types. Natural cellulose wettability eliminates the pre-wetting step required by hydrophobic membranes in aqueous sample filtration. Ultimately, standardized manufacturing protocols produce papers with retention and flow characteristics that remain constant from the first batch to the last.

Key Filter Paper Characteristics

• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Standard cellulose construction provides reliable performance for gravity filtration and light vacuum applications.
• Untreated cellulose construction provides the pure, unmodified surface appropriate for routine filtration and general sample preparation.
• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.

If your laboratory runs standardized filtration protocols, the lot-level consistency of this filter paper protects your method reproducibility. In this context, consistent sheet-to-sheet performance reduces the variability your operators encounter during high-volume daily filtration workflows. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
