Grade 589/1 Filter for Coarse Precipitate Retention, 150mm Circle (100 pcs) SKU: 10300012

Quantitative Ashless Filter Paper - 10300012

Environmental and pharmaceutical laboratories running ignition-based assays need ashless paper that meets their method's blank specifications. Tightly controlled manufacturing produces the lot-to-lot consistency that validated gravimetric methods depend on for reproducible results. To this end, each sheet reflects production standards where fiber density, thickness, and retention characteristics are verified before lot release.

Key Filter Paper Characteristics

• Certificate of analysis documents actual ash content per production lot, providing traceability for regulated analytical methods.
• Pure cellulose without strengthening additives ensures the lowest possible extractable background for sensitive analytical methods.
• Ashless filter paper provides the documented low residue needed for ignition-based analytical procedures where filter mass affects results.
• Manufactured under controlled acid washing conditions, each sheet delivers consistent ash levels across production lots for method reproducibility.
• Smooth surface finish facilitates complete precipitate recovery and clean separation from the paper during transfer operations.

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. Here, acid-washed cellulose removes the inorganic contaminants that would otherwise introduce blank errors in your ignition-based quantitative determinations. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
