Grade 1 Qualitative Filter Paper, Standard, 47cm x 100m Roll, 1 pack SKU: 1001-734

Qualitative Filter Paper - 1001-734

Gravity filtration setups require paper that wets uniformly, seats flat in funnels, and retains particles at the rated threshold. Available in circles, sheets, and prefolded formats to match specific funnel geometries and sample processing workflows. Because of this, quality-controlled production produces filter paper with the documented consistency that reproducible analytical and preparative methods demand.

Key Filter Paper Characteristics

• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Pure cellulose fiber construction without hardening treatment ensures minimal chemical background in filtered samples.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Rated at 11um particle retention, the fiber matrix provides a defined cutoff for consistent separation across analytical batches.

If you're transitioning from qualitative screening to quantitative gravimetric work, the documented ash content above confirms this paper's suitability. With these demands in mind, economical unit cost at the pack quantities routine laboratories consume keeps your filtration budget aligned with actual throughput demands. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
