Grade 589/3 Filter for Fine Precipitate Retention, 110mm Circle (100 pcs) SKU: 10300210

Quantitative Ashless Filter Paper - 10300210

Accurate mass-based determinations start with a filter medium whose residue after ignition is controlled, tested, and traceable. Certificate of analysis provides lot-specific ash content values for incorporation into method blank calculations and quality records. Consistent physical properties across the full sheet area support uniform filtration results in both gravity and vacuum applications.

Key Filter Paper Characteristics

• Certificate of analysis documents actual ash content per production lot, providing traceability for regulated analytical methods.
• Acid-washed cellulose construction produces ash content below 0.01%, meeting the blank value requirements of quantitative gravimetric methods.
• Controlled ash level at <0.01% ensures inorganic residue after ignition remains within the acceptable range for gravimetric procedures.
• Non-strengthened paper is appropriate for routine gravity filtration where prolonged vacuum exposure is not part of the workflow.
• Controlled fiber density balances rapid filtration with complete precipitate capture for efficient quantitative determinations.

Maintaining accreditation requires documented traceability at every step, and the grade specifications above support your audit readiness. Acid-washed cellulose removes the inorganic contaminants that would otherwise introduce blank errors in your ignition-based quantitative determinations. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
