Qualitative Filter Paper - 10314744
From student teaching labs to production QC departments, qualitative filter paper remains the workhorse for routine particle separation. Standard basis weight specifications provide predictable filter packing density for volumetric displacement calculations in funnel assemblies. To this end, from fiber selection through final inspection, the manufacturing process ensures every sheet meets the performance specifications of its grade.
Key Filter Paper Characteristics
- Wet-strengthened fiber matrix withstands extended contact with aqueous solutions without the disintegration that limits untreated papers.
- Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
- Basis weight of 88g/m² indicates the fiber mass per unit area that controls retention, flow rate, and wet strength.
- Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
- Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
Maintaining accreditation requires documented traceability at every step, and the grade specifications above support your audit readiness. Meeting this challenge, predictable retention and flow rate from a pure cellulose matrix give you a dependable filtration baseline for routine sample preparation. 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.
