Grade 595 1/2 Qualitative Filter Paper Folded (Prepleated), 385mm, 100/Pk SKU: 10311654

Qualitative Filter Paper - 10311654

Gravity filtration setups require paper that wets uniformly, seats flat in funnels, and retains particles at the rated threshold. Smooth surface finish allows clear visual assessment of retained solids and supports clean separation of precipitates from filtrate. Consequently, standardized manufacturing protocols produce papers with retention and flow characteristics that remain constant from the first batch to the last.

Key Filter Paper Characteristics

• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Basis weight of 68g/m² indicates the fiber mass per unit area that controls retention, flow rate, and wet strength.
• Rated at 4-7um particle retention, the fiber matrix provides a defined cutoff for consistent separation across analytical batches.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Standard cellulose without surface treatment delivers reliable performance for applications where chemical hardening is not required.

Whether your method requires simple clarification or precise gravimetric determination, the documented specifications above define what this paper delivers. Wide retention range availability across the qualitative grade family lets you optimize each application in your sample preparation workflow. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
