Quantitative Ashless Filter Paper, Medium Fast, 16 um, 110mm, 100/Pk SKU: CF15008

Quantitative Ashless Filter Paper - CF15008

Sulfate determination by precipitation requires filter paper whose ash content remains below the method's blank specification after ignition. Environmental and pharmaceutical laboratories running ignition-based assays need ashless paper that meets their method's blank specifications. By design, controlled manufacturing delivers the documented retention, flow rate, and physical consistency that analytical and preparative filtration methods require.

Key Filter Paper Characteristics

• Designed for gravimetric determinations where the filter paper is ashed or ignited as part of the analytical measurement step.
• Acid-washed cellulose construction produces ash content below 0.01%, meeting the blank value requirements of quantitative gravimetric methods.
• Non-hardened cellulose delivers the flow rates and retention that routine methods require at practical cost per determination.
• 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.

If your workflow includes both routine clarification and specialized quantitative methods, stocking this versatile grade reduces your inventory complexity. In practice, 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.
