Grade 0048 Application-Specific Filter, Circle, 32mm, 1000/Pk SKU: 10348903

Quantitative Ashless Filter Paper - 10348903

Gravimetric analysis demands filter paper that contributes virtually no residue after ignition, ensuring mass measurements reflect the sample alone. Cellulose purity and documented ash specifications position ashless paper as the standard medium for ignition-based quantitative determinations. By design, certificate of conformance documentation accompanies each lot, providing traceability for quality systems and regulatory audit requirements.

Key Filter Paper Characteristics

• Nominal basis weight of 95g/m² reflects the fiber density that determines flow rate, retention, and mechanical handling characteristics.
• Smooth surface finish facilitates complete precipitate recovery and clean separation from the paper during transfer operations.
• Controlled fiber density balances rapid filtration with complete precipitate capture for efficient quantitative determinations.
• Acid washing process removes metallic contaminants that could interfere with trace element determinations after ignition.
• Designed for gravimetric determinations where the filter paper is ashed or ignited as part of the analytical measurement step.

Maintaining accreditation requires documented traceability at every step, and the grade specifications above support your audit readiness. Uniform fiber density across the sheet area ensures your precipitate capture remains consistent from center to edge. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.
