Grade 2 Qualitative Filter Paper, Standard, 320mm Circle, 100/Pk SKU: 1002-320

Qualitative Filter Paper - 1002-320

Teaching laboratories introducing filtration techniques need a paper grade that produces reliable results while remaining cost-effective for student use. Cellulose fiber matrix maintains structural integrity through standard gravity and light vacuum filtration conditions. In sum, documented grade specifications provide laboratories with the technical data needed to select appropriate papers without preliminary testing.

Key Filter Paper Characteristics

• Non-strengthened grades deliver consistent retention at the economical price point that high-volume routine methods demand.
• At 97g/m² nominal basis weight, the paper provides the mass uniformity needed for reproducible gravimetric determinations.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.

If your teaching or research laboratory processes high volumes of routine samples, the documented flow rates above translate directly to throughput. Broad grade availability lets you match retention, flow rate, and thickness to each specific application in your method library. 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.
