Qualitative Filter Paper, Medium Slow, 6 um, 180mm, 100/Pk SKU: CF15050

Qualitative Filter Paper - CF15050

From student teaching labs to production QC departments, qualitative filter paper remains the workhorse for routine particle separation. Isolating precipitates from reaction mixtures requires a cellulose matrix that captures solid material completely without premature filter blinding. With this in mind, from fiber selection through final inspection, the manufacturing process ensures every sheet meets the performance specifications of its grade.

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 6um defines the separation threshold for the application, determining which solids are captured and which pass through.
• Unmodified cellulose surface provides natural hydrophilic properties for rapid wetting in aqueous filtration applications.
• 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.

When your application makes the filter paper part of the measurement, the ash and weight specifications above define its analytical contribution. To meet this need, rapid wetting and uniform pore distribution reduce the setup time your operators spend preparing each filtration run. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
