Grade 226 33 cm 100/Pk SKU: 5226-330

Qualitative Filter Paper - 5226-330

Routine laboratory filtration demands a filter paper that delivers consistent particle retention without slowing sample throughput. Controlled fiber density produces documented flow rate and retention characteristics that remain consistent across production lots. By design, rigorous quality control at every production stage ensures physical properties align with published grade specifications before distribution.

Key Filter Paper Characteristics

• Wet-strengthened construction provides the mechanical durability needed for technical filtration applications under sustained vacuum.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.

When your application makes the filter paper part of the measurement, the ash and weight specifications above define its analytical contribution. 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.
