Grade 597 Qualitative Filter Paper Standard Grade, Circle, 12.7mm, 1000/Pk SKU: 10311862

Qualitative Filter Paper - 10311862

Separating precipitates from analytical solutions requires a cellulose matrix with the right balance of retention and flow rate. Manufactured without chemical hardening or acid washing, qualitative cellulose delivers the unmodified surface properties routine filtration requires. In sum, standardized manufacturing protocols produce papers with retention and flow characteristics that remain constant from the first batch to the last.

Key Filter Paper Characteristics

• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Standard construction provides the soft, conformable surface that seats properly in gravity filtration funnels without edge leakage.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Rated at 4-7um particle retention, the fiber matrix provides a defined cutoff for consistent separation across analytical batches.

When your budget requires balancing performance with cost efficiency, the documented consistency above ensures you're not paying for premium features you don't need. For this application, economical unit cost at the pack quantities routine laboratories consume keeps your filtration budget aligned with actual throughput demands. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

• Soil Extract Filtration - Clarifies soil slurries for nutrient and pH testing, removing fine particles that interfere with analysis.
• General Clarification - Removes suspended solids from aqueous solutions by gravity filtration for routine sample preparation.
• Beverage Testing - Filters wine, beer, and juice samples before clarity and color measurements in food quality control laboratories.
• Polymer Filtration - Clears particulates from polymer solutions before molecular weight determination by viscometry or GPC.
• Lysate Clarification - Separates cellular debris from crude lysates before downstream chromatographic or electrophoretic analysis.
• Precipitation Recovery - Collects insoluble reaction products on the paper surface for subsequent washing and downstream analysis.
