Grade 2 Qualitative Filter Paper, Standard, 110mm Circle, 100/Pk SKU: 1002-110

Qualitative Filter Paper - 1002-110

Sample clarification before instrumental analysis starts with a filter paper that captures interfering particles without introducing extractable contamination. Uniform pore distribution across the sheet area ensures consistent particle capture from center to edge during gravity filtration. Certificate of conformance documentation accompanies each lot, providing traceability for quality systems and regulatory audit requirements.

Key Filter Paper Characteristics

• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Particle retention rating of 8um defines the separation threshold for the application, determining which solids are captured and which pass through.
• Standard cellulose construction eliminates chemical treatment steps that could introduce background contamination in sensitive analytical methods.
• Manufactured to a basis weight of 97g/m², each sheet delivers the documented mass consistency that gravimetric methods require.

Whether your method requires simple clarification or precise gravimetric determination, the documented specifications above define what this paper delivers. Under these conditions, standard cellulose chemistry eliminates the need for specialized disposal procedures your general laboratory filtration generates. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
