Grade 42 Ashless Filter Paper for Instrumental Analysis, 110mm Circle, 100/Pk SKU: 1442-110

Quantitative Ashless Filter Paper - 1442-110

Classical analytical methods requiring filter ignition with collected precipitate demand documented ash values verifiable through every production lot. Tightly controlled manufacturing produces the lot-to-lot consistency that validated gravimetric methods depend on for reproducible results. Certificate of conformance documentation accompanies each lot, providing traceability for quality systems and regulatory audit requirements.

Key Filter Paper Characteristics

• Smooth surface finish facilitates complete precipitate recovery and clean separation from the paper during transfer operations.
• Non-strengthened grades deliver consistent retention at the economical price point that high-volume routine methods demand.
• Tightly controlled manufacturing produces documented ash content that remains consistent across production lots for method reproducibility.
• At 100g/m² nominal basis weight, the paper provides the mass uniformity needed for reproducible gravimetric determinations.
• Ashless filter paper provides the documented low residue needed for ignition-based analytical procedures where filter mass affects results.

When your budget requires balancing performance with cost efficiency, the documented consistency above ensures you're not paying for premium features you don't need. Under these conditions, ultra-low ash content ensures your gravimetric results reflect captured material, not residue from the filter paper itself. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
