Qualitative Filter Paper, Medium, 8 um, 125mm, 100/Pk SKU: CF15041

Qualitative Filter Paper - CF15041

Teaching laboratories introducing filtration techniques need a paper grade that produces reliable results while remaining cost-effective for student use. Teaching laboratories introducing filtration techniques need a paper grade that produces reliable results while remaining cost-effective for student use. Consequently, standardized manufacturing protocols produce papers with retention and flow characteristics that remain constant from the first batch to the last.

Key Filter Paper Characteristics

• Controlled ash level at ≤0.15% ensures inorganic residue after ignition remains within the acceptable range for gravimetric procedures.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Pure cellulose without strengthening additives ensures the lowest possible extractable background for sensitive analytical methods.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.

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. In this context, broad grade availability lets you match retention, flow rate, and thickness to each specific application in your method library. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
