Grade 597 1/2 Qualitative Filter Paper Folded (Prepleated), 185mm, 100/Pk SKU: 10311847

Qualitative Filter Paper - 10311847

Gravity filtration methods for removing suspended solids require filter paper that seats cleanly in funnels and retains particles consistently. Cellulose fiber matrix maintains structural integrity through standard gravity and light vacuum filtration conditions. In effect, quality-controlled production produces filter paper with the documented consistency that reproducible analytical and preparative methods demand.

Key Filter Paper Characteristics

• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Rated at 4-7um particle retention, the fiber matrix provides a defined cutoff for consistent separation across analytical batches.
• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• 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.

When your application makes the filter paper part of the measurement, the ash and weight specifications above define its analytical contribution. For applications like these, sheet-to-sheet consistency means your training investment carries forward as new staff learn the same predictable filtration behavior. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
