Grade 1 Qualitative Filter Paper, Standard, 47mm Circle, 100/Pk SKU: 1001-047

Qualitative Filter Paper - 1001-047

Sample clarification before instrumental analysis starts with a filter paper that captures interfering particles without introducing extractable contamination. Manufactured without chemical hardening or acid washing, qualitative cellulose delivers the unmodified surface properties routine filtration requires. Consequently, quality-controlled production produces filter paper with the documented consistency that reproducible analytical and preparative methods demand.

Key Filter Paper Characteristics

• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Manufactured to a basis weight of 87g/m², each sheet delivers the documented mass consistency that gravimetric methods require.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.

When your application makes the filter paper part of the measurement, the ash and weight specifications above define its analytical contribution. Standard cellulose chemistry eliminates the need for specialized disposal procedures your general laboratory filtration generates. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
