Grade 54 Filter Paper, Fast, 500mm Circle, 100/Pk SKU: 1454-500

Quantitative Ashless Filter Paper - 1454-500

Environmental and pharmaceutical laboratories running ignition-based assays need ashless paper that meets their method's blank specifications. Acid washing removes metallic ions that could interfere with trace element determinations following ignition of the loaded filter. Working in concert, consistent physical properties across the full sheet area support uniform filtration results in both gravity and vacuum applications.

Key Filter Paper Characteristics

• Ashless filter paper provides the documented low residue needed for ignition-based analytical procedures where filter mass affects results.
• 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.
• Manufactured under controlled acid washing conditions, each sheet delivers consistent ash levels across production lots for method reproducibility.
• Pure cellulose fiber matrix combines low inorganic residue with the mechanical integrity needed for careful precipitate transfer.

If your environmental monitoring program depends on sample comparability to determine trends, the production consistency of this filter paper protects your data validity. For applications like these, acid-washed cellulose removes the inorganic contaminants that would otherwise introduce blank errors in your ignition-based quantitative determinations. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
