Quantitative Ashless Filter Paper - CF15010
Environmental and pharmaceutical laboratories running ignition-based assays need ashless paper that meets their method's blank specifications. Regulatory laboratories performing routine gravimetric assays need ashless paper with certificates of analysis documenting compliance with method specifications. Accordingly, lot-level verification of retention, thickness, and ash content ensures predictable performance when scaling from method development to routine analysis.
Key Filter Paper Characteristics
- Standard wet strength is sufficient for conventional Buchner funnel and gravity filtration setups at moderate sample volumes.
- Smooth surface finish facilitates complete precipitate recovery and clean separation from the paper during transfer operations.
- Designed for workflows where general-purpose flow rates limit productivity but fast-grade retention is too coarse for the application.
- Controlled ash level of ≤0.011% meets the blank value requirements of quantitative methods where filter contribution must be documented.
- Controlled fiber density balances rapid filtration with complete precipitate capture for efficient quantitative determinations.
If your laboratory runs standardized filtration protocols, the lot-level consistency of this filter paper protects your method reproducibility. To support this, premium cellulose purity reduces the blank correction calculations your gravimetric procedures would otherwise require. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
