Grade 5 Qualitative Filter Paper, Standard, 47mm Circle, 100/Pk SKU: 1005-047

Qualitative Filter Paper - 1005-047

Gravity filtration methods for removing suspended solids require filter paper that seats cleanly in funnels and retains particles consistently. Manufactured without chemical hardening or acid washing, qualitative cellulose delivers the unmodified surface properties routine filtration requires. Quality-controlled production produces filter paper with the documented consistency that reproducible analytical and preparative methods demand.

Key Filter Paper Characteristics

• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Manufactured to a basis weight of 100g/m², each sheet delivers the documented mass consistency that gravimetric methods require.
• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.

If your laboratory runs standardized filtration protocols, the lot-level consistency of this filter paper protects your method reproducibility. To that end, predictable retention and flow rate from a pure cellulose matrix give you a dependable filtration baseline for routine sample preparation. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
