Grade 595 1/2 Qualitative Filter Paper Folded (Prepleated), 185mm, 100/Pk SKU: 10311647

Qualitative Filter Paper - 10311647

General clarification and sample preparation workflows require a cellulose filter paper with predictable performance across varying sample types. Uniform pore distribution across the sheet area ensures consistent particle capture from center to edge during gravity filtration. In turn, documented grade specifications provide laboratories with the technical data needed to select appropriate papers without preliminary testing.

Key Filter Paper Characteristics

• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Standard cellulose construction provides reliable performance for gravity filtration and light vacuum applications.
• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• Particle retention rating of 4-7um defines the separation threshold for the application, determining which solids are captured and which pass through.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.

If your laboratory runs standardized filtration protocols, the lot-level consistency of this filter paper protects your method reproducibility. 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.
