Qualitative Filter Paper - 5202-330
Isolating precipitates from reaction mixtures requires a cellulose matrix that captures solid material completely without premature filter blinding. Natural cellulose wettability eliminates the pre-wetting step required by hydrophobic membranes in aqueous sample filtration. By design, certificate of conformance documentation accompanies each lot, providing traceability for quality systems and regulatory audit requirements.
Key Filter Paper Characteristics
- Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
- Particle retention rating of 15-19um defines the separation threshold for the application, determining which solids are captured and which pass through.
- Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
- Standard cellulose without surface treatment delivers reliable performance for applications where chemical hardening is not required.
- Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
Scaling your method from development to routine production requires paper consistency at every lot, and the specifications above provide that assurance. To meet this need, standard qualitative construction integrates into your existing funnel hardware, requiring no new equipment investment for reliable results. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
