Grade 93 Qualitative Filter Paper Wet-Strengthened, 150mm, 10 Bags of 100 Circles SKU: 1093-6215

Qualitative Filter Paper - 1093-6215

Gravity filtration methods for removing suspended solids require filter paper that seats cleanly in funnels and retains particles consistently. Uniform pore distribution across the sheet area ensures consistent particle capture from center to edge during gravity filtration. For this reason, from fiber selection through final inspection, the manufacturing process ensures every sheet meets the performance specifications of its grade.

Key Filter Paper Characteristics

• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• Rated at 10.0um particle retention, the fiber matrix provides a defined cutoff for consistent separation across analytical batches.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.

If your environmental monitoring program depends on sample comparability to determine trends, the production consistency of this filter paper protects your data validity. In these cases, broad grade availability lets you match retention, flow rate, and thickness to each specific application in your method library. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
