Grade 2V Qualitative Filter Paper, Pre-Folded, 150mm Circle, 100/Pk SKU: 1202-150

Qualitative Filter Paper - 1202-150

Separating precipitates from analytical solutions requires a cellulose matrix with the right balance of retention and flow rate. Uniform pore distribution across the sheet area ensures consistent particle capture from center to edge during gravity filtration. On this basis, quality-controlled production produces filter paper with the documented consistency that reproducible analytical and preparative methods demand.

Key Filter Paper Characteristics

• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• Standard cellulose without surface treatment delivers reliable performance for applications where chemical hardening is not required.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
• 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. To address this, sheet-to-sheet consistency means your training investment carries forward as new staff learn the same predictable filtration behavior. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
