Grade 595 Qualitative Filter Paper Standard Grade, Circle, 150mm, 100/Pk SKU: 10311612

Qualitative Filter Paper - 10311612

Isolating precipitates from reaction mixtures requires a cellulose matrix that captures solid material completely without premature filter blinding. Pure cotton linter cellulose provides a uniform fiber matrix with consistent porosity and predictable retention across standard grade designations. In effect, 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 qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Nominal basis weight of 68g/m² reflects the fiber density that determines flow rate, retention, and mechanical handling characteristics.

If your laboratory supports multiple research groups with varying filtration needs, this paper's broad applicability simplifies your procurement process. For this application, sheet-to-sheet consistency means your training investment carries forward as new staff learn the same predictable filtration behavior. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
