Grade 802 38.5cm Diameter 100/Pk SKU: 5802-385

Qualitative Filter Paper - 5802-385

Routine quality control filtration across multiple product lines requires a filter paper that delivers consistent retention without batch-to-batch performance drift. Smooth surface finish allows clear visual assessment of retained solids and supports clean separation of precipitates from filtrate. Working in concert, certificate of conformance documentation accompanies each lot, providing traceability for quality systems and regulatory audit requirements.

Key Filter Paper Characteristics

• Resin-bonded fiber structure resists progressive weakening that causes standard papers to fail during extended vacuum filtration cycles.
• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Basis weight of 73g/m² indicates the fiber mass per unit area that controls retention, flow rate, and wet strength.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.

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. In response, wide retention range availability across the qualitative grade family lets you optimize each application in your sample preparation workflow. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
