Quantitative Ashless Filter Paper, Slow 2-4 um, 110mm, 100/Pk SKU: CF15020

Quantitative Ashless Filter Paper - CF15020

Quantitative methods where the filter is ashed alongside the sample require documented, ultra-low residue to protect analytical accuracy. Quantitative methods where the filter is ashed alongside the sample require documented, ultra-low residue to protect analytical accuracy. Because of this, controlled manufacturing delivers the documented retention, flow rate, and physical consistency that analytical and preparative filtration methods require.

Key Filter Paper Characteristics

• Ashless filter paper provides the documented low residue needed for ignition-based analytical procedures where filter mass affects results.
• Non-strengthened paper is appropriate for routine gravity filtration where prolonged vacuum exposure is not part of the workflow.
• Nominal basis weight of 80±5g/m² reflects the fiber density that determines flow rate, retention, and mechanical handling characteristics.
• Controlled fiber density balances rapid filtration with complete precipitate capture for efficient quantitative determinations.
• Untreated cellulose construction provides the pure, unmodified surface appropriate for routine filtration and general sample preparation.

Your sample preparation workflow benefits from a filter paper whose performance is defined, documented, and consistent from one purchase to the next. Addressing this directly, 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.
