Grade 2 Qualitative Filter Paper, Standard, 150mm Circle, 100/Pk SKU: 1002-150

Qualitative Filter Paper - 1002-150

Gravity filtration methods for removing suspended solids require filter paper that seats cleanly in funnels and retains particles consistently. Pure cotton linter cellulose provides a uniform fiber matrix with consistent porosity and predictable retention across standard grade designations. 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

• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Standard cellulose construction eliminates chemical treatment steps that could introduce background contamination in sensitive analytical methods.
• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.

If your environmental monitoring program depends on sample comparability to determine trends, the production consistency of this filter paper protects your data validity. 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.
