Grade 2 Qualitative Filter Paper, Standard, 185mm Circle, 100/Pk SKU: 1002-185

Qualitative Filter Paper - 1002-185

Laboratories processing dozens of samples daily need a qualitative filter paper that performs reliably from the first sheet to the last. Medium retention grades capture suspended solids while maintaining flow rates suitable for routine laboratory sample throughput requirements. Documented grade specifications provide laboratories with the technical data needed to select appropriate papers without preliminary testing.

Key Filter Paper Characteristics

• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Untreated cellulose construction provides the pure, unmodified surface appropriate for routine filtration and general sample preparation.
• Non-strengthened grades deliver consistent retention at the economical price point that high-volume routine methods demand.

Your sample preparation workflow benefits from a filter paper whose performance is defined, documented, and consistent from one purchase to the next. In particular, standard cellulose chemistry eliminates the need for specialized disposal procedures your general laboratory filtration generates. 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.

• Soil Extract Filtration - Clarifies soil slurries for nutrient and pH testing, removing fine particles that interfere with analysis.
• Botanical Extraction - Separates plant tissue debris from aqueous and solvent extracts during natural product preparation workflows.
• Lysate Clarification - Separates cellular debris from crude lysates before downstream chromatographic or electrophoretic analysis.
• Polymer Filtration - Clears particulates from polymer solutions before molecular weight determination by viscometry or GPC.
• Pigment Screening - Separates undispersed colorant particles from coating formulations during color development and QC testing.
• Enzyme Clarification - Removes particulates from enzyme solutions before activity assays in biochemistry and industrial testing.
