Grade 230 20CM 50/Pk SKU: 5230-200

Qualitative Filter Paper - 5230-200

Laboratories processing dozens of samples daily need a qualitative filter paper that performs reliably from the first sheet to the last. Smooth surface finish allows clear visual assessment of retained solids and supports clean separation of precipitates from filtrate. To this end, from fiber selection through final inspection, the manufacturing process ensures every sheet meets the performance specifications of its grade.

Key Filter Paper Characteristics

• At 123g/m² nominal basis weight, the paper provides the mass uniformity needed for reproducible gravimetric determinations.
• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.

If your teaching or research laboratory processes high volumes of routine samples, the documented flow rates above translate directly to throughput. Sheet-to-sheet consistency means your training investment carries forward as new staff learn the same predictable filtration behavior. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
