Shark Skin Filter Paper for Technical Use, 185mm Circle, 100/Pk SKU: 10347512

Qualitative Filter Paper - 10347512

Separating precipitates from analytical solutions requires a cellulose matrix with the right balance of retention and flow rate. Cellulose fiber matrix maintains structural integrity through standard gravity and light vacuum filtration conditions. Quality-controlled production produces filter paper with the documented consistency that reproducible analytical and preparative methods demand.

Key Filter Paper Characteristics

• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Pure cellulose fiber construction without hardening treatment ensures minimal chemical background in filtered samples.
• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.

If your workflow includes both routine clarification and specialized quantitative methods, stocking this versatile grade reduces your inventory complexity. For this application, economical unit cost at the pack quantities routine laboratories consume keeps your filtration budget aligned with actual throughput demands. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

• 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.
• Teaching Laboratory - Provides consistent and economical filtration media for student exercises in analytical and general chemistry.
• Gelatin Clarification - Removes debris from gelatin solutions used in pharmaceutical capsule manufacturing and quality testing.
• Lysate Clarification - Separates cellular debris from crude lysates before downstream chromatographic or electrophoretic analysis.
• Soil Extract Filtration - Clarifies soil slurries for nutrient and pH testing, removing fine particles that interfere with analysis.
