Grade 52 Filter Paper, General, 150mm Circle, 100/Pk SKU: 1452-150

Quantitative Ashless Filter Paper - 1452-150

Gravimetric procedures in regulated laboratories require documented ash content that can be reported alongside analytical results for compliance verification. Smooth fiber surface facilitates clean precipitate release during transfer operations from funnel to crucible. In practice, quality-controlled production produces filter paper with the documented consistency that reproducible analytical and preparative methods demand.

Key Filter Paper Characteristics

• Controlled fiber density balances rapid filtration with complete precipitate capture for efficient quantitative determinations.
• Resin treatment provides the tensile strength to resist tearing under vacuum, even when processing large sample volumes.
• Certificate of analysis documents actual ash content per production lot, providing traceability for regulated analytical methods.
• Pure cellulose fiber matrix combines low inorganic residue with the mechanical integrity needed for careful precipitate transfer.
• Nominal basis weight of 96g/m² reflects the fiber density that determines flow rate, retention, and mechanical handling characteristics.

If your environmental monitoring program depends on sample comparability to determine trends, the production consistency of this filter paper protects your data validity. Certificate-backed ash specifications provide the documented evidence your quality auditors require for gravimetric method validation. 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.
