Grade 6 Qualitative Filter Paper, Standard, 42.5mm Circle, 100/Pk SKU: 1006-042

Qualitative Filter Paper - 1006-042

Sample clarification before instrumental analysis starts with a filter paper that captures interfering particles without introducing extractable contamination. Standard basis weight specifications provide predictable filter packing density for volumetric displacement calculations in funnel assemblies. Because of this, certificate of conformance documentation accompanies each lot, providing traceability for quality systems and regulatory audit requirements.

Key Filter Paper Characteristics

• Standard cellulose without surface treatment delivers reliable performance for applications where chemical hardening is not required.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Standard construction delivers adequate wet strength for conventional filtration while maintaining economical cost for routine applications.

If your environmental monitoring program depends on sample comparability to determine trends, the production consistency of this filter paper protects your data validity. To support this, broad grade availability lets you match retention, flow rate, and thickness to each specific application in your method library. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
