Quantitative Ashless Filter Pape, Medium Fast, 16 um, 90mm, 100/Pk SKU: CF15007

Quantitative Ashless Filter Paper - CF15007

Trace-level determinations by ignition depend on filter paper with ash content low enough to fall within method-acceptable blank ranges. Environmental and pharmaceutical laboratories running ignition-based assays need ashless paper that meets their method's blank specifications. Taken together, each sheet reflects production standards where fiber density, thickness, and retention characteristics are verified before lot release.

Key Filter Paper Characteristics

• Non-hardened cellulose delivers the flow rates and retention that routine methods require at practical cost per determination.
• Designed for gravimetric determinations where the filter paper is ashed or ignited as part of the analytical measurement step.
• Smooth surface finish facilitates complete precipitate recovery and clean separation from the paper during transfer operations.
• Tightly controlled manufacturing produces documented ash content that remains consistent across production lots for method reproducibility.
• Controlled fiber density balances rapid filtration with complete precipitate capture for efficient quantitative determinations.

If your teaching or research laboratory processes high volumes of routine samples, the documented flow rates above translate directly to throughput. For applications like these, premium cellulose purity reduces the blank correction calculations your gravimetric procedures would otherwise require. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
