Grade 5 Qualitative Filter Paper, Standard, 125mm Circle, 100/Pk SKU: 1005-125

Qualitative Filter Paper - 1005-125

Gravity filtration setups require paper that wets uniformly, seats flat in funnels, and retains particles at the rated threshold. Medium retention grades capture suspended solids while maintaining flow rates suitable for routine laboratory sample throughput requirements. In sum, rigorous quality control at every production stage ensures physical properties align with published grade specifications before distribution.

Key Filter Paper Characteristics

• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Manufactured to a basis weight of 100g/m², each sheet delivers the documented mass consistency that gravimetric methods require.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
• Untreated cellulose construction provides the pure, unmodified surface appropriate for routine filtration and general sample preparation.

If your workflow includes both routine clarification and specialized quantitative methods, stocking this versatile grade reduces your inventory complexity. Under these conditions, rapid wetting and uniform pore distribution reduce the setup time your operators spend preparing each filtration run. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
