Grade 201 Cellulose Filter Paper, 33 cm Circle, 100/Pk SKU: 5201-330

Qualitative Filter Paper - 5201-330

Routine quality control filtration across multiple product lines requires a filter paper that delivers consistent retention without batch-to-batch performance drift. Cellulose fiber matrix maintains structural integrity through standard gravity and light vacuum filtration conditions. Ultimately, rigorous quality control at every production stage ensures physical properties align with published grade specifications before distribution.

Key Filter Paper Characteristics

• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• Enhanced mechanical properties support high differential pressures typical of vacuum manifold applications in high-volume laboratories.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.

Your sample preparation workflow benefits from a filter paper whose performance is defined, documented, and consistent from one purchase to the next. For this purpose, 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.
