Grade 2 Qualitative Filter Paper, Standard, 385mm Circle, 100/Pk SKU: 1002-385

Qualitative Filter Paper - 1002-385

Routine quality control filtration across multiple product lines requires a filter paper that delivers consistent retention without batch-to-batch performance drift. Pure cotton linter cellulose provides a uniform fiber matrix with consistent porosity and predictable retention across standard grade designations. Rigorous quality control at every production stage ensures physical properties align with published grade specifications before distribution.

Key Filter Paper Characteristics

• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Nominal basis weight of 97g/m² reflects the fiber density that determines flow rate, retention, and mechanical handling characteristics.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.

Your sample preparation workflow benefits from a filter paper whose performance is defined, documented, and consistent from one purchase to the next. Cotton linter cellulose provides the clean fiber background your general analytical methods need without the cost of specialty grades. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
