Grade 2294 Filter Paper for Technical Use, Circle, 180mm w/ Central Hole 33mm, 100 SKU: 10342860

Qualitative Filter Paper - 10342860

General clarification and sample preparation workflows require a cellulose filter paper with predictable performance across varying sample types. Cellulose fiber matrix maintains structural integrity through standard gravity and light vacuum filtration conditions. Because of this, lot-level verification of retention, thickness, and ash content ensures predictable performance when scaling from method development to routine analysis.

Key Filter Paper Characteristics

• Resin-bonded fiber structure resists progressive weakening that causes standard papers to fail during extended vacuum filtration cycles.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• 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.

When your multi-site study requires comparable data across laboratories, papers manufactured to tight documented specifications ensure your results align. Standard cellulose chemistry eliminates the need for specialized disposal procedures your general laboratory filtration generates. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
