Grade 93 Qualitative Filter Paper Wet-Strengthened, 110mm Circle, 100/Pk SKU: 1093-110

Qualitative Filter Paper - 1093-110

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. As a result, consistent physical properties across the full sheet area support uniform filtration results in both gravity and vacuum applications.

Key Filter Paper Characteristics

• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Particle retention rating of 10.0um defines the separation threshold for the application, determining which solids are captured and which pass through.

When your multi-site study requires comparable data across laboratories, papers manufactured to tight documented specifications ensure your results align. Predictable retention and flow rate from a pure cellulose matrix give you a dependable filtration baseline for routine sample preparation. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
