Grade 2555 1/2 Qualitative Filter Paper Folded (Prepleated), 320mm, 100/Pk SKU: 10313953

Qualitative Filter Paper - 10313953

Gravity filtration setups require paper that wets uniformly, seats flat in funnels, and retains particles at the rated threshold. Smooth surface finish allows clear visual assessment of retained solids and supports clean separation of precipitates from filtrate. Certificate of conformance documentation accompanies each lot, providing traceability for quality systems and regulatory audit requirements.

Key Filter Paper Characteristics

• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Standard construction delivers adequate wet strength for conventional filtration while maintaining economical cost for routine applications.
• Nominal basis weight of 75g/m² reflects the fiber density that determines flow rate, retention, and mechanical handling characteristics.
• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.

When your multi-site study requires comparable data across laboratories, papers manufactured to tight documented specifications ensure your results align. For this purpose, cotton linter cellulose provides the clean fiber background your general analytical methods need without the cost of specialty grades. 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.

• Paint and Coatings QC - Removes gels and undispersed pigment from coating samples prior to color measurement and viscosity testing.
• Teaching Laboratory - Provides consistent and economical filtration media for student exercises in analytical and general chemistry.
• General Clarification - Removes suspended solids from aqueous solutions by gravity filtration for routine sample preparation.
• Precipitation Recovery - Collects insoluble reaction products on the paper surface for subsequent washing and downstream analysis.
• 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.
