Grade 595 Qualitative Filter Paper Standard Grade, Sheet, 580x580mm, 500/Pk SKU: 10311687

Qualitative Filter Paper - 10311687

Routine laboratory filtration demands a filter paper that delivers consistent particle retention without slowing sample throughput. Manufactured without chemical hardening or acid washing, qualitative cellulose delivers the unmodified surface properties routine filtration requires. Working in concert, consistent physical properties across the full sheet area support uniform filtration results in both gravity and vacuum applications.

Key Filter Paper Characteristics

• At 4-7um rated retention, the fiber matrix captures particles above the threshold while allowing smaller materials to pass through.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Manufactured to a basis weight of 68g/m², each sheet delivers the documented mass consistency that gravimetric methods require.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.

If your teaching or research laboratory processes high volumes of routine samples, the documented flow rates above translate directly to throughput. With this in mind, economical unit cost at the pack quantities routine laboratories consume keeps your filtration budget aligned with actual throughput demands. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
