Grade 589/3 Filter for Fine Precipitate Retention, 150mm Circle (100 pcs) SKU: 10300212

Quantitative Ashless Filter Paper - 10300212

Sulfate determination by precipitation requires filter paper whose ash content remains below the method's blank specification after ignition. Tightly controlled manufacturing produces the lot-to-lot consistency that validated gravimetric methods depend on for reproducible results. For this reason, consistent physical properties across the full sheet area support uniform filtration results in both gravity and vacuum applications.

Key Filter Paper Characteristics

• Standard construction provides the absorption and wicking characteristics that gravity-based filtration protocols require.
• Ashless filter paper provides the documented low residue needed for ignition-based analytical procedures where filter mass affects results.
• Tightly controlled manufacturing produces documented ash content that remains consistent across production lots for method reproducibility.
• Controlled fiber density balances rapid filtration with complete precipitate capture for efficient quantitative determinations.
• Acid-washed cellulose construction produces ash content below 0.01%, meeting the blank value requirements of quantitative gravimetric methods.

If your teaching or research laboratory processes high volumes of routine samples, the documented flow rates above translate directly to throughput. With this in mind, premium cellulose purity reduces the blank correction calculations your gravimetric procedures would otherwise require. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
