Grade 52 Filter Paper, General, 110mm Circle, 100/Pk SKU: 1452-110

Quantitative Ashless Filter Paper - 1452-110

Trace-level determinations by ignition depend on filter paper with ash content low enough to fall within method-acceptable blank ranges. Controlled washing process removes metallic and mineral contaminants that would otherwise contribute measurable mass after ignition. Together, controlled manufacturing delivers the documented retention, flow rate, and physical consistency that analytical and preparative filtration methods require.

Key Filter Paper Characteristics

• Manufactured under controlled acid washing conditions, each sheet delivers consistent ash levels across production lots for method reproducibility.
• Wet-strengthened fiber matrix withstands extended contact with aqueous solutions without the disintegration that limits untreated papers.
• Ashless filter paper provides the documented low residue needed for ignition-based analytical procedures where filter mass affects results.
• Certificate of analysis documents actual ash content per production lot, providing traceability for regulated analytical methods.
• 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. Specifically, uniform fiber density across the sheet area ensures your precipitate capture remains consistent from center to edge. 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.
