Grade 602 h 1/2 Qualitative Filter Paper Folded (Prepleated), 125mm, 100/Pk SKU: 10312644

Qualitative Filter Paper - 10312644

Laboratories processing dozens of samples daily need a qualitative filter paper that performs reliably from the first sheet to the last. Medium retention grades capture suspended solids while maintaining flow rates suitable for routine laboratory sample throughput requirements. Rigorous quality control at every production stage ensures physical properties align with published grade specifications before distribution.

Key Filter Paper Characteristics

• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• At <2um rated retention, the fiber matrix captures particles above the threshold while allowing smaller materials to pass through.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.

Whether your method requires simple clarification or precise gravimetric determination, the documented specifications above define what this paper delivers. With this in mind, standard qualitative construction integrates into your existing funnel hardware, requiring no new equipment investment for reliable results. 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.
