Grade 602 h Qualitative Filter Paper Standard Grade, Circle, 125mm, 100/Pk SKU: 10312611

Qualitative Filter Paper - 10312611

Laboratories processing dozens of samples daily need a qualitative filter paper that performs reliably from the first sheet to the last. Manufactured without chemical hardening or acid washing, qualitative cellulose delivers the unmodified surface properties routine filtration requires. In effect, standardized manufacturing protocols produce papers with retention and flow characteristics that remain constant from the first batch to the last.

Key Filter Paper Characteristics

• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• At <2um rated retention, the fiber matrix captures particles above the threshold while allowing smaller materials to pass through.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.

If your laboratory runs standardized filtration protocols, the lot-level consistency of this filter paper protects your method reproducibility. Broad grade availability lets you match retention, flow rate, and thickness to each specific application in your method library. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
