Grade 2589 d Filter Paper for Technical Use, Sheet, 25x75mm, 100/Pk SKU: 10343976

Qualitative Filter Paper - 10343976

Teaching laboratories introducing filtration techniques need a paper grade that produces reliable results while remaining cost-effective for student use. Natural cellulose wettability eliminates the pre-wetting step required by hydrophobic membranes in aqueous sample filtration. Altogether, rigorous quality control at every production stage ensures physical properties align with published grade specifications before distribution.

Key Filter Paper Characteristics

• Particle retention rating of 2-6um defines the separation threshold for the application, determining which solids are captured and which pass through.
• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.

Your sample preparation workflow benefits from a filter paper whose performance is defined, documented, and consistent from one purchase to the next. Standard cellulose chemistry eliminates the need for specialized disposal procedures your general laboratory filtration generates. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
