Grade 5 Qualitative Filter Paper, Standard, 110mm Circle, 100/Pk SKU: 1005-110

Qualitative Filter Paper - 1005-110

Separating precipitates from analytical solutions requires a cellulose matrix with the right balance of retention and flow rate. Natural cellulose wettability eliminates the pre-wetting step required by hydrophobic membranes in aqueous sample filtration. Standardized manufacturing protocols produce papers with retention and flow characteristics that remain constant from the first batch to the last.

Key Filter Paper Characteristics

• At 100g/m² nominal basis weight, the paper provides the mass uniformity needed for reproducible gravimetric determinations.
• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
• Non-strengthened grades deliver consistent retention at the economical price point that high-volume routine methods demand.

When your quality system requires documented specifications for every consumable, the grade data above provides the traceability your auditors expect. Addressing this directly, broad grade availability lets you match retention, flow rate, and thickness to each specific application in your method library. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
