Grade 5 Qualitative Filter Paper, Standard, 185mm Circle, 100/Pk SKU: 1005-185

Qualitative Filter Paper - 1005-185

Isolating precipitates from reaction mixtures requires a cellulose matrix that captures solid material completely without premature filter blinding. Available in circles, sheets, and prefolded formats to match specific funnel geometries and sample processing workflows. Accordingly, quality-controlled production produces filter paper with the documented consistency that reproducible analytical and preparative methods demand.

Key Filter Paper Characteristics

• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Nominal basis weight of 100g/m² reflects the fiber density that determines flow rate, retention, and mechanical handling characteristics.
• Particle retention rating of 2.5um defines the separation threshold for the application, determining which solids are captured and which pass through.
• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• 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. To support this, rapid wetting and uniform pore distribution reduce the setup time your operators spend preparing each filtration run. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

• Paint and Coatings QC - Removes gels and undispersed pigment from coating samples prior to color measurement and viscosity testing.
• Polymer Filtration - Clears particulates from polymer solutions before molecular weight determination by viscometry or GPC.
• General Clarification - Removes suspended solids from aqueous solutions by gravity filtration for routine sample preparation.
• Gelatin Clarification - Removes debris from gelatin solutions used in pharmaceutical capsule manufacturing and quality testing.
• Soil Extract Filtration - Clarifies soil slurries for nutrient and pH testing, removing fine particles that interfere with analysis.
• Enzyme Clarification - Removes particulates from enzyme solutions before activity assays in biochemistry and industrial testing.
