Grade 1 Qualitative Filter Paper, Standard, 30mm Circle, 400 pack SKU: 1001-030

Qualitative Filter Paper - 1001-030

Teaching laboratories introducing filtration techniques need a paper grade that produces reliable results while remaining cost-effective for student use. Pure cotton linter cellulose provides a uniform fiber matrix with consistent porosity and predictable retention across standard grade designations. Consequently, certificate of conformance documentation accompanies each lot, providing traceability for quality systems and regulatory audit requirements.

Key Filter Paper Characteristics

• Non-hardened paper balances effective particle retention with economical unit cost for high-volume routine laboratory use.
• Pure cellulose without strengthening additives ensures the lowest possible extractable background for sensitive analytical methods.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• 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.

Scaling your method from development to routine production requires paper consistency at every lot, and the specifications above provide that assurance. To that end, predictable retention and flow rate from a pure cellulose matrix give you a dependable filtration baseline for routine sample preparation. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
