Grade 1 Qualitative Filter Paper, Standard, 15mm Circle, 500 pack SKU: 1001-0155

Qualitative Filter Paper - 1001-0155

From student teaching labs to production QC departments, qualitative filter paper remains the workhorse for routine particle separation. Available in circles, sheets, and prefolded formats to match specific funnel geometries and sample processing workflows. By design, controlled manufacturing delivers the documented retention, flow rate, and physical consistency that analytical and preparative filtration methods require.

Key Filter Paper Characteristics

• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• At 87g/m² nominal basis weight, the paper provides the mass uniformity needed for reproducible gravimetric determinations.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.

When your quality system requires documented specifications for every consumable, the grade data above provides the traceability your auditors expect. Cotton linter cellulose provides the clean fiber background your general analytical methods need without the cost of specialty grades. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
