Qualitative Filter Paper - 5230-250

Isolating precipitates from reaction mixtures requires a cellulose matrix that captures solid material completely without premature filter blinding. Standard basis weight specifications provide predictable filter packing density for volumetric displacement calculations in funnel assemblies. To this end, controlled manufacturing delivers the documented retention, flow rate, and physical consistency that analytical and preparative filtration methods require.

Key Filter Paper Characteristics

• At 123g/m² nominal basis weight, the paper provides the mass uniformity needed for reproducible gravimetric determinations.
• Particle retention rating of 25-30um defines the separation threshold for the application, determining which solids are captured and which pass through.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.

If your laboratory runs standardized filtration protocols, the lot-level consistency of this filter paper protects your method reproducibility. In response, cotton linter cellulose provides the clean fiber background your general analytical methods need without the cost of specialty grades. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
