Grade 3 Qualitative Filter Paper, Standard, 55mm Circle, 100/Pk SKU: 1003-055

Qualitative Filter Paper - 1003-055

General clarification and sample preparation workflows require a cellulose filter paper with predictable performance across varying sample types. Controlled fiber density produces documented flow rate and retention characteristics that remain consistent across production lots. With this in mind, certificate of conformance documentation accompanies each lot, providing traceability for quality systems and regulatory audit requirements.

Key Filter Paper Characteristics

• Nominal retention of 6um provides the particle size cutoff appropriate for the analytical or preparative separation method.
• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.

When your quality system requires documented specifications for every consumable, the grade data above provides the traceability your auditors expect. Addressing this directly, rapid wetting and uniform pore distribution reduce the setup time your operators spend preparing each filtration run. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
