Grade 50 Filter Paper, Thin, 110mm Circle, 100/Pk SKU: 1450-110

Quantitative Ashless Filter Paper - 1450-110

Quantitative methods where the filter is ashed alongside the sample require documented, ultra-low residue to protect analytical accuracy. Certificate of analysis provides lot-specific ash content values for incorporation into method blank calculations and quality records. Consequently, documented grade specifications provide laboratories with the technical data needed to select appropriate papers without preliminary testing.

Key Filter Paper Characteristics

• Manufactured under controlled acid washing conditions, each sheet delivers consistent ash levels across production lots for method reproducibility.
• Wet-strengthened construction provides the mechanical durability needed for technical filtration applications under sustained vacuum.
• Chemical hardening of the cellulose fiber matrix provides the durability needed for quantitative procedures involving hot or corrosive reagents.
• Ashless filter paper provides the documented low residue needed for ignition-based analytical procedures where filter mass affects results.
• Designed for gravimetric determinations where the filter paper is ashed or ignited as part of the analytical measurement step.

If your environmental monitoring program depends on sample comparability to determine trends, the production consistency of this filter paper protects your data validity. In practice, ultra-low ash content ensures your gravimetric results reflect captured material, not residue from the filter paper itself. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
