Shark Skin Filter Paper for Technical Use, 270mm Circle, 100/Pk SKU: 10347521

Qualitative Filter Paper - 10347521

Routine laboratory filtration demands a filter paper that delivers consistent particle retention without slowing sample throughput. Medium retention grades capture suspended solids while maintaining flow rates suitable for routine laboratory sample throughput requirements. Quality-controlled production produces filter paper with the documented consistency that reproducible analytical and preparative methods demand.

Key Filter Paper Characteristics

• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• Enhanced wet strength allows vacuum filtration at higher differential pressures without risking paper rupture mid-run.
• Particle retention rating of 8-12um defines the separation threshold for the application, determining which solids are captured and which pass through.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.

If your laboratory supports multiple research groups with varying filtration needs, this paper's broad applicability simplifies your procurement process. Standard qualitative construction integrates into your existing funnel hardware, requiring no new equipment investment for reliable results. 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.

• Paint and Coatings QC - Removes gels and undispersed pigment from coating samples prior to color measurement and viscosity testing.
• Precipitation Recovery - Collects insoluble reaction products on the paper surface for subsequent washing and downstream analysis.
• Soil Extract Filtration - Clarifies soil slurries for nutrient and pH testing, removing fine particles that interfere with analysis.
• Pigment Screening - Separates undispersed colorant particles from coating formulations during color development and QC testing.
• Gelatin Clarification - Removes debris from gelatin solutions used in pharmaceutical capsule manufacturing and quality testing.
• Polymer Filtration - Clears particulates from polymer solutions before molecular weight determination by viscometry or GPC.
