Shark Skin Filter Paper for Technical Use, 320mm Circle, 100/Pk SKU: 10347530

Qualitative Filter Paper - 10347530

Isolating precipitates from reaction mixtures requires a cellulose matrix that captures solid material completely without premature filter blinding. Standard basis weight specifications provide predictable filter packing density for volumetric displacement calculations in funnel assemblies. Together, documented grade specifications provide laboratories with the technical data needed to select appropriate papers without preliminary testing.

Key Filter Paper Characteristics

• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Manufactured to a basis weight of 44g/m², each sheet delivers the documented mass consistency that gravimetric methods require.
• 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.
• Rated at 8-12um particle retention, the fiber matrix provides a defined cutoff for consistent separation across analytical batches.

When your budget requires balancing performance with cost efficiency, the documented consistency above ensures you're not paying for premium features you don't need. In practice, 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.
