Grade 541 Ashless Fast Filter Paper, 125mm Circles (100 pcs) SKU: 1541-125

Quantitative Ashless Filter Paper - 1541-125

Quantitative methods where the filter is ashed alongside the sample require documented, ultra-low residue to protect analytical accuracy. Cellulose purity and documented ash specifications position ashless paper as the standard medium for ignition-based quantitative determinations. In combination, rigorous quality control at every production stage ensures physical properties align with published grade specifications before distribution.

Key Filter Paper Characteristics

• Ashless filter paper provides the documented low residue needed for ignition-based analytical procedures where filter mass affects results.
• Certificate of analysis documents actual ash content per production lot, providing traceability for regulated analytical methods.
• Hardened filter paper resists tearing when wet, simplifying the transfer of collected precipitates from funnel to crucible.
• Controlled ash level of <0.006% 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.

Your sample preparation workflow benefits from a filter paper whose performance is defined, documented, and consistent from one purchase to the next. In particular, ashless purity positions this paper as your standard medium for any method where the filter becomes part of the final measurement. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
