Grade 541 Ashless Fast Filter Paper, Sheet, 460x570mm Sheet (100 pcs) SKU: 1541-917

Quantitative Ashless Filter Paper - 1541-917

Regulatory laboratories performing routine gravimetric assays need ashless paper with certificates of analysis documenting compliance with method specifications. Fine fiber matrix delivers the mechanical integrity needed to transfer collected precipitates from funnel to crucible without loss. Altogether, certificate of conformance documentation accompanies each lot, providing traceability for quality systems and regulatory audit requirements.

Key Filter Paper Characteristics

• 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.
• Chemical hardening of the cellulose fiber matrix provides the durability needed for quantitative procedures involving hot or corrosive reagents.
• Tightly controlled manufacturing produces documented ash content that remains consistent across production lots for method reproducibility.
• Acid-washed cellulose construction produces ash content below 0.01%, meeting the blank value requirements of quantitative gravimetric methods.

When your application makes the filter paper part of the measurement, the ash and weight specifications above define its analytical contribution. In this context, fine fiber construction provides the mechanical integrity you need to transfer collected precipitates to the crucible without sample loss. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
