Grade 2 Qualitative Filter Paper, Standard, 150mm Circle, 100/Pk cert. for IS Testing SKU: 1002-147

Qualitative Filter Paper - 1002-147

General clarification and sample preparation workflows require a cellulose filter paper with predictable performance across varying sample types. Medium retention grades capture suspended solids while maintaining flow rates suitable for routine laboratory sample throughput requirements. Lot-level verification of retention, thickness, and ash content ensures predictable performance when scaling from method development to routine analysis.

Key Filter Paper Characteristics

• Ash content of 0.06% provides the documented blank value specification that quantitative analytical methods require.
• Pure cellulose fiber construction without hardening treatment ensures minimal chemical background in filtered samples.
• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.

Your sample preparation workflow benefits from a filter paper whose performance is defined, documented, and consistent from one purchase to the next. Sheet-to-sheet consistency means your training investment carries forward as new staff learn the same predictable filtration behavior. 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.
