Qualitative Filter Paper, Medium, 8 um, 110mm, 100/Pk SKU: CF15040

Qualitative Filter Paper - CF15040

Laboratories processing dozens of samples daily need a qualitative filter paper that performs reliably from the first sheet to the last. General clarification and sample preparation workflows require a cellulose filter paper with predictable performance across varying sample types. Consequently, from fiber selection through final inspection, the manufacturing process ensures every sheet meets the performance specifications of its grade.

Key Filter Paper Characteristics

• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Nominal ash content of ≤0.15% ensures minimal inorganic residue after ignition, protecting the accuracy of gravimetric determinations.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
• Standard flow rate delivers predictable performance across the sample types most commonly processed in teaching and research labs.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.

When your budget requires balancing performance with cost efficiency, the documented consistency above ensures you're not paying for premium features you don't need. Specifically, rapid wetting and uniform pore distribution reduce the setup time your operators spend preparing each filtration run. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.
