Grade 5 Qualitative Filter Paper, Standard, 90mm Circle, 100/Pk SKU: 1005-090

Qualitative Filter Paper - 1005-090

From student teaching labs to production QC departments, qualitative filter paper remains the workhorse for routine particle separation. Uniform pore distribution across the sheet area ensures consistent particle capture from center to edge during gravity filtration. Working in concert, certificate of conformance documentation accompanies each lot, providing traceability for quality systems and regulatory audit requirements.

Key Filter Paper Characteristics

• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• Standard cellulose without surface treatment delivers reliable performance for applications where chemical hardening is not required.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.

If your environmental monitoring program depends on sample comparability to determine trends, the production consistency of this filter paper protects your data validity. Predictable retention and flow rate from a pure cellulose matrix give you a dependable filtration baseline for routine sample preparation. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.
