Shark Skin Filter Paper for Technical Use, 290mm Circle, 100/Pk SKU: 10347577

Qualitative Filter Paper - 10347577

Laboratories processing dozens of samples daily need a qualitative filter paper that performs reliably from the first sheet to the last. Standard basis weight specifications provide predictable filter packing density for volumetric displacement calculations in funnel assemblies. Lot-level verification of retention, thickness, and ash content ensures predictable performance when scaling from method development to routine analysis.

Key Filter Paper Characteristics

• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• At 8-12um rated retention, the fiber matrix captures particles above the threshold while allowing smaller materials to pass through.
• At 44g/m² nominal basis weight, the paper provides the mass uniformity needed for reproducible gravimetric determinations.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.

Reporting filtration parameters alongside your analytical results demands documented grade, retention, and lot traceability for reviewer confidence. For this application, cotton linter cellulose provides the clean fiber background your general analytical methods need without the cost of specialty grades. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
