Grade 50 Filter Paper, Thin, 500mm Circle, 100/Pk SKU: 1450-500

Quantitative Ashless Filter Paper - 1450-500

Gravimetric procedures in regulated laboratories require documented ash content that can be reported alongside analytical results for compliance verification. Tightly controlled manufacturing produces the lot-to-lot consistency that validated gravimetric methods depend on for reproducible results. Ultimately, documented grade specifications provide laboratories with the technical data needed to select appropriate papers without preliminary testing.

Key Filter Paper Characteristics

• Tightly controlled manufacturing produces documented ash content that remains consistent across production lots for method reproducibility.
• Certificate of analysis documents actual ash content per production lot, providing traceability for regulated analytical methods.
• Ash content of <0.015% provides the documented blank value specification that quantitative analytical methods require.
• Chemical hardening of the cellulose fiber matrix provides the durability needed for quantitative procedures involving hot or corrosive reagents.
• Manufactured under controlled acid washing conditions, each sheet delivers consistent ash levels across production lots for method reproducibility.

If your environmental monitoring program depends on sample comparability to determine trends, the production consistency of this filter paper protects your data validity. To support this, ashless certification supports the regulatory compliance documentation your environmental and pharmaceutical methods demand. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
