Shark Skin Filter Paper for Technical Use, 150mm Circle, 100/Pk SKU: 10347513

Qualitative Filter Paper - 10347513

Sample clarification before instrumental analysis starts with a filter paper that captures interfering particles without introducing extractable contamination. Medium retention grades capture suspended solids while maintaining flow rates suitable for routine laboratory sample throughput requirements. Controlled manufacturing delivers the documented retention, flow rate, and physical consistency that analytical and preparative filtration methods require.

Key Filter Paper Characteristics

• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Resin treatment provides the tensile strength to resist tearing under vacuum, even when processing large sample volumes.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• At 44g/m² nominal basis weight, the paper provides the mass uniformity needed for reproducible gravimetric determinations.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.

If your teaching or research laboratory processes high volumes of routine samples, the documented flow rates above translate directly to throughput. Meeting this challenge, wide retention range availability across the qualitative grade family lets you optimize each application in your sample preparation workflow. 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.
