Grade 6 Qualitative Filter Paper, Standard, 70mm Circle, 100/Pk SKU: 1006-070

Qualitative Filter Paper - 1006-070

Laboratories processing dozens of samples daily need a qualitative filter paper that performs reliably from the first sheet to the last. Uniform pore distribution across the sheet area ensures consistent particle capture from center to edge during gravity filtration. Together, consistent physical properties across the full sheet area support uniform filtration results in both gravity and vacuum applications.

Key Filter Paper Characteristics

• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Controlled ash level at 0.06% ensures inorganic residue after ignition remains within the acceptable range for gravimetric procedures.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Pure cellulose fiber construction without hardening treatment ensures minimal chemical background in filtered samples.

Reporting filtration parameters alongside your analytical results demands documented grade, retention, and lot traceability for reviewer confidence. Standard cellulose chemistry eliminates the need for specialized disposal procedures your general laboratory filtration generates. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
