Shark Skin Filter Paper for Technical Use, 90mm Circle, 100/Pk SKU: 10347509

Qualitative Filter Paper - 10347509

Teaching laboratories introducing filtration techniques need a paper grade that produces reliable results while remaining cost-effective for student use. 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

• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
• Non-hardened cellulose delivers the flow rates and retention that routine methods require at practical cost per determination.
• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.

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. To support this, standard cellulose chemistry eliminates the need for specialized disposal procedures your general laboratory filtration generates. 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.
