Grade 93 Qualitative Filter Paper Wet-Strengthened, 125mm Circle, 100/Pk SKU: 1093-125

Qualitative Filter Paper - 1093-125

Separating precipitates from analytical solutions requires a cellulose matrix with the right balance of retention and flow rate. Pure cotton linter cellulose provides a uniform fiber matrix with consistent porosity and predictable retention across standard grade designations. Controlled manufacturing delivers the documented retention, flow rate, and physical consistency that analytical and preparative filtration methods require.

Key Filter Paper Characteristics

• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Particle retention rating of 10.0um defines the separation threshold for the application, determining which solids are captured and which pass through.
• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.

When your multi-site study requires comparable data across laboratories, papers manufactured to tight documented specifications ensure your results align. Cotton linter cellulose provides the clean fiber background your general analytical methods need without the cost of specialty grades. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.
