Grade 230 40cm 50/Pk SKU: 5230-400

Qualitative Filter Paper - 5230-400

Routine laboratory filtration demands a filter paper that delivers consistent particle retention without slowing sample throughput. Medium retention grades capture suspended solids while maintaining flow rates suitable for routine laboratory sample throughput requirements. With this in mind, standardized manufacturing protocols produce papers with retention and flow characteristics that remain constant from the first batch to the last.

Key Filter Paper Characteristics

• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Enhanced mechanical properties support high differential pressures typical of vacuum manifold applications in high-volume laboratories.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.

If your workflow includes both routine clarification and specialized quantitative methods, stocking this versatile grade reduces your inventory complexity. To support this, standard cellulose chemistry eliminates the need for specialized disposal procedures your general laboratory filtration generates. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

• Botanical Extraction - Separates plant tissue debris from aqueous and solvent extracts during natural product preparation workflows.
• 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.
• Precipitation Recovery - Collects insoluble reaction products on the paper surface for subsequent washing and downstream analysis.
