Qualitative Filter Paper - 10314712
Teaching laboratories introducing filtration techniques need a paper grade that produces reliable results while remaining cost-effective for student use. Manufactured without chemical hardening or acid washing, qualitative cellulose delivers the unmodified surface properties routine filtration requires. Together, from fiber selection through final inspection, the manufacturing process ensures every sheet meets the performance specifications of its grade.
Key Filter Paper Characteristics
- Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
- Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
- Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
- Nominal retention of 12-25um provides the particle size cutoff appropriate for the analytical or preparative separation method.
- Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
When your multi-site study requires comparable data across laboratories, papers manufactured to tight documented specifications ensure your results align. To meet this need, consistent sheet-to-sheet performance reduces the variability your operators encounter during high-volume daily filtration workflows. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
