Grade 93 Qualitative Filter Paper Wet-Strengthened, 61x61mm Sheet, 500 Pk SKU: 1093-935

Qualitative Filter Paper - 1093-935

General clarification and sample preparation workflows require a cellulose filter paper with predictable performance across varying sample types. Controlled fiber density produces documented flow rate and retention characteristics that remain consistent across production lots. As designed, certificate of conformance documentation accompanies each lot, providing traceability for quality systems and regulatory audit requirements.

Key Filter Paper Characteristics

• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Strengthening treatment preserves paper structure through extended filtration runs where continuous wetting would weaken standard grades.
• Basis weight of 65g/m² indicates the fiber mass per unit area that controls retention, flow rate, and wet strength.
• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.

If your teaching or research laboratory processes high volumes of routine samples, the documented flow rates above translate directly to throughput. In these cases, broad grade availability lets you match retention, flow rate, and thickness to each specific application in your method library. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
