Grade 3 Qualitative Filter Paper, Standard, 460x570mm Sheet, 100/Pk SKU: 1003-917

Qualitative Filter Paper - 1003-917

Isolating precipitates from reaction mixtures requires a cellulose matrix that captures solid material completely without premature filter blinding. Natural cellulose wettability eliminates the pre-wetting step required by hydrophobic membranes in aqueous sample filtration. Each sheet reflects production standards where fiber density, thickness, and retention characteristics are verified before lot release.

Key Filter Paper Characteristics

• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Standard cellulose construction eliminates chemical treatment steps that could introduce background contamination in sensitive analytical methods.
• Rated at 6um particle retention, the fiber matrix provides a defined cutoff for consistent separation across analytical batches.
• 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. To address this, cotton linter cellulose provides the clean fiber background your general analytical methods need without the cost of specialty grades. 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.
