Grade 0790 1/2 Application-Specific Filter, Folded, 150mm, 100/Pk SKU: 10301645

Qualitative Filter Paper - 10301645

Gravity filtration methods for removing suspended solids require filter paper that seats cleanly in funnels and retains particles consistently. Controlled fiber density produces documented flow rate and retention characteristics that remain consistent across production lots. In effect, lot-level verification of retention, thickness, and ash content ensures predictable performance when scaling from method development to routine analysis.

Key Filter Paper Characteristics

• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
• Basis weight of 75g/m² indicates the fiber mass per unit area that controls retention, flow rate, and wet strength.

Scaling your method from development to routine production requires paper consistency at every lot, and the specifications above provide that assurance. With these demands in mind, standard cellulose chemistry eliminates the need for specialized disposal procedures your general laboratory filtration generates. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
