Grade 54 Filter Paper, Fast, 240mm Circle, 100/Pk SKU: 1454-240

Quantitative Ashless Filter Paper - 1454-240

Gravimetric procedures in regulated laboratories require documented ash content that can be reported alongside analytical results for compliance verification. Cellulose purity and documented ash specifications position ashless paper as the standard medium for ignition-based quantitative determinations. By design, controlled manufacturing delivers the documented retention, flow rate, and physical consistency that analytical and preparative filtration methods require.

Key Filter Paper Characteristics

• Acid-washed cellulose construction produces ash content below 0.01%, meeting the blank value requirements of quantitative gravimetric methods.
• Hardened construction withstands aggressive solvents and concentrated acids that would compromise untreated cellulose papers.
• Controlled fiber density balances rapid filtration with complete precipitate capture for efficient quantitative determinations.
• Smooth surface finish facilitates complete precipitate recovery and clean separation from the paper during transfer operations.
• Pure cellulose fiber matrix combines low inorganic residue with the mechanical integrity needed for careful precipitate transfer.

When your application makes the filter paper part of the measurement, the ash and weight specifications above define its analytical contribution. Ashless purity positions this paper as your standard medium for any method where the filter becomes part of the final measurement. 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.
