Grade 201 Cellulose Filter Paper, 11 cm Circle, 100/Pk SKU: 5201-110

Qualitative Filter Paper - 5201-110

General clarification and sample preparation workflows require a cellulose filter paper with predictable performance across varying sample types. Manufactured without chemical hardening or acid washing, qualitative cellulose delivers the unmodified surface properties routine filtration requires. Consequently, standardized manufacturing protocols produce papers with retention and flow characteristics that remain constant from the first batch to the last.

Key Filter Paper Characteristics

• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• At Medium Fine rated retention, the fiber matrix captures particles above the threshold while allowing smaller materials to pass through.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Enhanced wet strength allows vacuum filtration at higher differential pressures without risking paper rupture mid-run.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.

If you're transitioning from qualitative screening to quantitative gravimetric work, the documented ash content above confirms this paper's suitability. Specifically, wide retention range availability across the qualitative grade family lets you optimize each application in your sample preparation workflow. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
