602eh FF 125mm 100/Pk 20/Pk SKU: 10312544

Qualitative Filter Paper - 10312544

General clarification and sample preparation workflows require a cellulose filter paper with predictable performance across varying sample types. Available in circles, sheets, and prefolded formats to match specific funnel geometries and sample processing workflows. In turn, controlled manufacturing delivers the documented retention, flow rate, and physical consistency that analytical and preparative filtration methods require.

Key Filter Paper Characteristics

• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Nominal basis weight of 85g/m² reflects the fiber density that determines flow rate, retention, and mechanical handling characteristics.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.

Scaling your method from development to routine production requires paper consistency at every lot, and the specifications above provide that assurance. To address this, rapid wetting and uniform pore distribution reduce the setup time your operators spend preparing each filtration run. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
