Grade 201 Cellulose Filter Paper, 9 cm Circle, 100/Pk SKU: 5201-090

Qualitative Filter Paper - 5201-090

From student teaching labs to production QC departments, qualitative filter paper remains the workhorse for routine particle separation. Cellulose fiber matrix maintains structural integrity through standard gravity and light vacuum filtration conditions. Ultimately, from fiber selection through final inspection, the manufacturing process ensures every sheet meets the performance specifications of its grade.

Key Filter Paper Characteristics

• Standard cellulose without surface treatment delivers reliable performance for applications where chemical hardening is not required.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• 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.
• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.

When your multi-site study requires comparable data across laboratories, papers manufactured to tight documented specifications ensure your results align. Meeting this challenge, rapid wetting and uniform pore distribution reduce the setup time your operators spend preparing each filtration run. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
