Shark Skin Filter Paper for Technical Use, 385mm Circle, 100/Pk SKU: 10347523

Qualitative Filter Paper - 10347523

Separating precipitates from analytical solutions requires a cellulose matrix with the right balance of retention and flow rate. Controlled fiber density produces documented flow rate and retention characteristics that remain consistent across production lots. In sum, each sheet reflects production standards where fiber density, thickness, and retention characteristics are verified before lot release.

Key Filter Paper Characteristics

• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• Untreated cellulose construction provides the pure, unmodified surface appropriate for routine filtration and general sample preparation.
• Resin treatment provides the tensile strength to resist tearing under vacuum, even when processing large sample volumes.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Nominal retention of 8-12um provides the particle size cutoff appropriate for the analytical or preparative separation method.

If your environmental monitoring program depends on sample comparability to determine trends, the production consistency of this filter paper protects your data validity. For applications like these, predictable retention and flow rate from a pure cellulose matrix give you a dependable filtration baseline for routine sample preparation. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
