Shark Skin Filter Paper for Technical Use, 110mm Circle, 100/Pk SKU: 10347510

Qualitative Filter Paper - 10347510

General clarification and sample preparation workflows require a cellulose filter paper with predictable performance across varying sample types. Medium retention grades capture suspended solids while maintaining flow rates suitable for routine laboratory sample throughput requirements. To this end, consistent physical properties across the full sheet area support uniform filtration results in both gravity and vacuum applications.

Key Filter Paper Characteristics

• Manufactured to a basis weight of 44g/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.
• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• Non-hardened cellulose delivers the flow rates and retention that routine methods require at practical cost per determination.

If your laboratory runs standardized filtration protocols, the lot-level consistency of this filter paper protects your method reproducibility. Sheet-to-sheet consistency means your training investment carries forward as new staff learn the same predictable filtration behavior. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
