Grade 1 Qualitative Filter Paper, Standard, 460x570mm Sheet, 500 pack SKU: 1001-918

Qualitative Filter Paper - 1001-918

Routine laboratory filtration demands a filter paper that delivers consistent particle retention without slowing sample throughput. Controlled fiber density produces documented flow rate and retention characteristics that remain consistent across production lots. Rigorous quality control at every production stage ensures physical properties align with published grade specifications before distribution.

Key Filter Paper Characteristics

• Standard cellulose without surface treatment delivers reliable performance for applications where chemical hardening is not required.
• Particle retention rating of 11um 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.
• 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.

If your teaching or research laboratory processes high volumes of routine samples, the documented flow rates above translate directly to throughput. 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.

• Soil Extract Filtration - Clarifies soil slurries for nutrient and pH testing, removing fine particles that interfere with analysis.
• Beverage Testing - Filters wine, beer, and juice samples before clarity and color measurements in food quality control laboratories.
• Teaching Laboratory - Provides consistent and economical filtration media for student exercises in analytical and general chemistry.
• Lysate Clarification - Separates cellular debris from crude lysates before downstream chromatographic or electrophoretic analysis.
• Enzyme Clarification - Removes particulates from enzyme solutions before activity assays in biochemistry and industrial testing.
• Precipitation Recovery - Collects insoluble reaction products on the paper surface for subsequent washing and downstream analysis.
