Grade 512 1/2 Application-Specific Filter, Folded, 185mm, 100/Pk SKU: 10310647

Qualitative Filter Paper - 10310647

Separating precipitates from analytical solutions requires a cellulose matrix with the right balance of retention and flow rate. Smooth surface finish allows clear visual assessment of retained solids and supports clean separation of precipitates from filtrate. In combination, lot-level verification of retention, thickness, and ash content ensures predictable performance when scaling from method development to routine analysis.

Key Filter Paper Characteristics

• Pure cellulose fiber construction without hardening treatment ensures minimal chemical background in filtered samples.
• At 76-84g/m² nominal basis weight, the paper provides the mass uniformity needed for reproducible gravimetric determinations.
• 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.
• Rated at 7-12um particle retention, the fiber matrix provides a defined cutoff for consistent separation across analytical batches.

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. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
