Grade 542 Ashless Fine Precipitate Filter, 55mm Circles (100 pcs) SKU: 1542-055

Quantitative Ashless Filter Paper - 1542-055

Regulatory laboratories performing routine gravimetric assays need ashless paper with certificates of analysis documenting compliance with method specifications. Fine fiber matrix delivers the mechanical integrity needed to transfer collected precipitates from funnel to crucible without loss. Rigorous quality control at every production stage ensures physical properties align with published grade specifications before distribution.

Key Filter Paper Characteristics

• Pure cellulose fiber matrix combines low inorganic residue with the mechanical integrity needed for careful precipitate transfer.
• 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.
• Hardened surface treatment increases wet strength and chemical resistance for demanding analytical procedures.
• Nominal ash content of <0.006% ensures minimal inorganic residue after ignition, protecting the accuracy of gravimetric determinations.

Whether your method requires simple clarification or precise gravimetric determination, the documented specifications above define what this paper delivers. For this application, consistent lot-to-lot ash values mean your validated gravimetric method stays valid without recalibrating blank corrections between purchases. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
