Grade 541 Ashless Fast Filter Paper, 110mm Circles (100 pcs) SKU: 1541-110

Quantitative Ashless Filter Paper - 1541-110

Multi-step analytical procedures ending in gravimetric determination need paper that survives reagent contact and delivers minimal residue on ignition. Cellulose purity and documented ash specifications position ashless paper as the standard medium for ignition-based quantitative determinations. In sum, rigorous quality control at every production stage ensures physical properties align with published grade specifications before distribution.

Key Filter Paper Characteristics

• Smooth surface finish facilitates complete precipitate recovery and clean separation from the paper during transfer operations.
• At 82g/m² nominal basis weight, the paper provides the mass uniformity needed for reproducible gravimetric determinations.
• Acid washing process removes metallic contaminants that could interfere with trace element determinations after ignition.
• Chemical hardening of the cellulose fiber matrix provides the durability needed for quantitative procedures involving hot or corrosive reagents.
• Controlled ash level at <0.006% ensures inorganic residue after ignition remains within the acceptable range for gravimetric procedures.

If your environmental monitoring program depends on sample comparability to determine trends, the production consistency of this filter paper protects your data validity. To meet this need, documented ash specifications on every lot give you the traceability your regulated analytical methods and quality audits require. 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.
