Grade 595 1/2 Qualitative Filter Paper Folded (Prepleated), 125mm, 100/Pk SKU: 10311644

Qualitative Filter Paper - 10311644

Gravity filtration methods for removing suspended solids require filter paper that seats cleanly in funnels and retains particles consistently. Standard basis weight specifications provide predictable filter packing density for volumetric displacement calculations in funnel assemblies. In sum, from fiber selection through final inspection, the manufacturing process ensures every sheet meets the performance specifications of its grade.

Key Filter Paper Characteristics

• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Rated at 4-7um particle retention, the fiber matrix provides a defined cutoff for consistent separation across analytical batches.
• 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.

Reporting filtration parameters alongside your analytical results demands documented grade, retention, and lot traceability for reviewer confidence. With these demands in mind, broad grade availability lets you match retention, flow rate, and thickness to each specific application in your method library. 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.
