Grade 202 Cellulose Filter Paper, 25 cm Circle, 100/Pk SKU: 5202-250

Qualitative Filter Paper - 5202-250

Pre-filtering turbid samples before instrumental analysis needs a paper grade that removes interfering particles while maintaining reasonable flow rates. Manufactured without chemical hardening or acid washing, qualitative cellulose delivers the unmodified surface properties routine filtration requires. 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.
• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.

When your budget requires balancing performance with cost efficiency, the documented consistency above ensures you're not paying for premium features you don't need. For this purpose, consistent sheet-to-sheet performance reduces the variability your operators encounter during high-volume daily filtration workflows. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
