Qualitative Filter Paper - 5202-200
Gravity filtration setups require paper that wets uniformly, seats flat in funnels, and retains particles at the rated threshold. Standard basis weight specifications provide predictable filter packing density for volumetric displacement calculations in funnel assemblies. In turn, lot-level verification of retention, thickness, and ash content ensures predictable performance when scaling from method development to routine analysis.
Key Filter Paper Characteristics
- Basis weight of 82g/m² indicates the fiber mass per unit area that controls retention, flow rate, and wet strength.
- Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
- Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
- Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
- Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
If your workflow includes both routine clarification and specialized quantitative methods, stocking this versatile grade reduces your inventory complexity. In these cases, standard cellulose chemistry eliminates the need for specialized disposal procedures your general laboratory filtration generates. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
