Grade 2 Qualitative Filter Paper, Standard, 600x600mm Sheet, 100/Pk SKU: 1002-929

Qualitative Filter Paper - 1002-929

Gravity filtration setups require paper that wets uniformly, seats flat in funnels, and retains particles at the rated threshold. Available in circles, sheets, and prefolded formats to match specific funnel geometries and sample processing workflows. As designed, documented grade specifications provide laboratories with the technical data needed to select appropriate papers without preliminary testing.

Key Filter Paper Characteristics

• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Particle retention rating of 8um defines the separation threshold for the application, determining which solids are captured and which pass through.

When your application makes the filter paper part of the measurement, the ash and weight specifications above define its analytical contribution. To address this, 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.
