Shark Skin Filter Paper for Technical Use, 21 in. x 750 ft Roll, 1 Pk SKU: 10537138

Qualitative Filter Paper - 10537138

From student teaching labs to production QC departments, qualitative filter paper remains the workhorse for routine particle separation. Natural cellulose wettability eliminates the pre-wetting step required by hydrophobic membranes in aqueous sample filtration. Controlled manufacturing delivers the documented retention, flow rate, and physical consistency that analytical and preparative filtration methods require.

Key Filter Paper Characteristics

• 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.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.

Your sample preparation workflow benefits from a filter paper whose performance is defined, documented, and consistent from one purchase to the next. Meeting this challenge, sheet-to-sheet consistency means your training investment carries forward as new staff learn the same predictable filtration behavior. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
