Grade 6 Qualitative Filter Paper, Standard, 150mm Circle, 100/Pk SKU: 1006-150

Qualitative Filter Paper - 1006-150

Routine laboratory filtration demands a filter paper that delivers consistent particle retention without slowing sample throughput. Manufactured without chemical hardening or acid washing, qualitative cellulose delivers the unmodified surface properties routine filtration requires. Certificate of conformance documentation accompanies each lot, providing traceability for quality systems and regulatory audit requirements.

Key Filter Paper Characteristics

• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• Basis weight of 100g/m² indicates the fiber mass per unit area that controls retention, flow rate, and wet strength.
• Nominal ash content of 0.06% ensures minimal inorganic residue after ignition, protecting the accuracy of gravimetric determinations.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.

If your environmental monitoring program depends on sample comparability to determine trends, the production consistency of this filter paper protects your data validity. Wide retention range availability across the qualitative grade family lets you optimize each application in your sample preparation workflow. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.
