Quantitative Ashless Filter Paper, Medium, 8 um, 90mm, 100/Pk SKU: CF15013

Quantitative Ashless Filter Paper - CF15013

Multi-step analytical procedures ending in gravimetric determination need paper that survives reagent contact and delivers minimal residue on ignition. Regulatory laboratories performing routine gravimetric assays need ashless paper with certificates of analysis documenting compliance with method specifications. From fiber selection through final inspection, the manufacturing process ensures every sheet meets the performance specifications of its grade.

Key Filter Paper Characteristics

• Acid-washed cellulose construction produces ash content below 0.01%, meeting the blank value requirements of quantitative gravimetric methods.
• Manufactured under controlled acid washing conditions, each sheet delivers consistent ash levels across production lots for method reproducibility.
• Designed for gravimetric determinations where the filter paper is ashed or ignited as part of the analytical measurement step.
• Smooth surface finish facilitates complete precipitate recovery and clean separation from the paper during transfer operations.
• Pure cellulose fiber construction without hardening treatment ensures minimal chemical background in filtered samples.

When your application makes the filter paper part of the measurement, the ash and weight specifications above define its analytical contribution. In this context, certificate-backed ash specifications provide the documented evidence your quality auditors require for gravimetric method validation. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
