Grade 1 Qualitative Filter Paper, Standard, 75x100mm Sheet, 500 pack SKU: 1001-824

Qualitative Filter Paper - 1001-824

From student teaching labs to production QC departments, qualitative filter paper remains the workhorse for routine particle separation. Standard basis weight specifications provide predictable filter packing density for volumetric displacement calculations in funnel assemblies. On this basis, rigorous quality control at every production stage ensures physical properties align with published grade specifications before distribution.

Key Filter Paper Characteristics

• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• Manufactured to a basis weight of 87g/m², each sheet delivers the documented mass consistency that gravimetric methods require.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.

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. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
