Grade 54 Filter Paper, Fast, 125mm Circle, 100/Pk SKU: 1454-125

Quantitative Ashless Filter Paper - 1454-125

Environmental and pharmaceutical laboratories running ignition-based assays need ashless paper that meets their method's blank specifications. Smooth fiber surface facilitates clean precipitate release during transfer operations from funnel to crucible. Certificate of conformance documentation accompanies each lot, providing traceability for quality systems and regulatory audit requirements.

Key Filter Paper Characteristics

• Designed for gravimetric determinations where the filter paper is ashed or ignited as part of the analytical measurement step.
• Controlled fiber density balances rapid filtration with complete precipitate capture for efficient quantitative determinations.
• Wet-strengthened fiber matrix withstands extended contact with aqueous solutions without the disintegration that limits untreated papers.
• 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.

When your application makes the filter paper part of the measurement, the ash and weight specifications above define its analytical contribution. In particular, ashless certification supports the regulatory compliance documentation your environmental and pharmaceutical methods demand. 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.
