Grade 520 bll Filter Paper for Technical Use, Sheet, 580x580mm SKU: 10331687

Qualitative Filter Paper - 10331687

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. In practice, standardized manufacturing protocols produce papers with retention and flow characteristics that remain constant from the first batch to the last.

Key Filter Paper Characteristics

• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Enhanced wet strength allows vacuum filtration at higher differential pressures without risking paper rupture mid-run.
• Nominal retention of 15-19um provides the particle size cutoff appropriate for the analytical or preparative separation method.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.

If your workflow includes both routine clarification and specialized quantitative methods, stocking this versatile grade reduces your inventory complexity. 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.

• Pigment Screening - Separates undispersed colorant particles from coating formulations during color development and QC testing.
• Lysate Clarification - Separates cellular debris from crude lysates before downstream chromatographic or electrophoretic analysis.
• Beverage Testing - Filters wine, beer, and juice samples before clarity and color measurements in food quality control laboratories.
• Polymer Filtration - Clears particulates from polymer solutions before molecular weight determination by viscometry or GPC.
• Soil Extract Filtration - Clarifies soil slurries for nutrient and pH testing, removing fine particles that interfere with analysis.
• Precipitation Recovery - Collects insoluble reaction products on the paper surface for subsequent washing and downstream analysis.
