Grade 512 1/2 Application-Specific Filter, Folded, 110mm, 100/Pk SKU: 10310643

Qualitative Filter Paper - 10310643

Laboratories processing dozens of samples daily need a qualitative filter paper that performs reliably from the first sheet to the last. Standard basis weight specifications provide predictable filter packing density for volumetric displacement calculations in funnel assemblies. As a result, standardized manufacturing protocols produce papers with retention and flow characteristics that remain constant from the first batch to the last.

Key Filter Paper Characteristics

• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Particle retention rating of 7-12um defines the separation threshold for the application, determining which solids are captured and which pass through.
• Nominal basis weight of 76-84g/m² reflects the fiber density that determines flow rate, retention, and mechanical handling characteristics.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.

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. In practice, broad grade availability lets you match retention, flow rate, and thickness to each specific application in your method library. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
