Grade 589/1 Filter for Coarse Precipitate Retention, 110mm Circle (100 pcs) SKU: 10300010

Quantitative Ashless Filter Paper - 10300010

Analytical laboratories performing routine gravimetric work need filter paper with consistent, documented ash values across every production lot. Tightly controlled manufacturing produces the lot-to-lot consistency that validated gravimetric methods depend on for reproducible results. Taken together, rigorous quality control at every production stage ensures physical properties align with published grade specifications before distribution.

Key Filter Paper Characteristics

• Certificate of analysis documents actual ash content per production lot, providing traceability for regulated analytical methods.
• Manufactured to a basis weight of 80g/m², each sheet delivers the documented mass consistency that gravimetric methods require.
• Controlled fiber density balances rapid filtration with complete precipitate capture for efficient quantitative determinations.
• Ashless filter paper provides the documented low residue needed for ignition-based analytical procedures where filter mass affects results.
• Acid-washed cellulose construction produces ash content below 0.01%, meeting the blank value requirements of quantitative gravimetric methods.

If your workflow includes both routine clarification and specialized quantitative methods, stocking this versatile grade reduces your inventory complexity. Certificate-backed ash specifications provide the documented evidence your quality auditors require for gravimetric method validation. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
