Qualitative Filter Paper - 5230-150

Separating precipitates from analytical solutions requires a cellulose matrix with the right balance of retention and flow rate. Controlled fiber density produces documented flow rate and retention characteristics that remain consistent across production lots. On this basis, consistent physical properties across the full sheet area support uniform filtration results in both gravity and vacuum applications.

Key Filter Paper Characteristics

• Standard cellulose without surface treatment delivers reliable performance for applications where chemical hardening is not required.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• At 123g/m² nominal basis weight, the paper provides the mass uniformity needed for reproducible gravimetric determinations.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.

If you're transitioning from qualitative screening to quantitative gravimetric work, the documented ash content above confirms this paper's suitability. To address this, rapid wetting and uniform pore distribution reduce the setup time your operators spend preparing each filtration run. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
