Thumbnail Filmstrip of Quantitative Ashless Filter Paper, Medium, 8 um, 125mm, 100/Pk Images
Quantitative Ashless Filter Paper - CF15015
Classical analytical methods requiring filter ignition with collected precipitate demand documented ash values verifiable through every production lot. Regulatory laboratories performing routine gravimetric assays need ashless paper with certificates of analysis documenting compliance with method specifications. To this end, certificate of conformance documentation accompanies each lot, providing traceability for quality systems and regulatory audit requirements.
Key Filter Paper Characteristics
- Standard cellulose without surface treatment delivers reliable performance for applications where chemical hardening is not required.
- Controlled ash level at ≤0.011% ensures inorganic residue after ignition remains within the acceptable range for gravimetric procedures.
- Manufactured under controlled acid washing conditions, each sheet delivers consistent ash levels across production lots for method reproducibility.
- Smooth surface finish facilitates complete precipitate recovery and clean separation from the paper during transfer operations.
- Certificate of analysis documents actual ash content per production lot, providing traceability for regulated analytical methods.
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. Meeting this challenge, ultra-low ash content ensures your gravimetric results reflect captured material, not residue from the filter paper itself. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
