Grade 2V Qualitative Filter Paper, Pre-Folded, 385mm Circle, 100/Pk SKU: 1202-385

Qualitative Filter Paper - 1202-385

Gravity filtration methods for removing suspended solids require filter paper that seats cleanly in funnels and retains particles consistently. Available in circles, sheets, and prefolded formats to match specific funnel geometries and sample processing workflows. Accordingly, standardized manufacturing protocols produce papers with retention and flow characteristics that remain constant from the first batch to the last.

Key Filter Paper Characteristics

• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.

Reporting filtration parameters alongside your analytical results demands documented grade, retention, and lot traceability for reviewer confidence. Here, economical unit cost at the pack quantities routine laboratories consume keeps your filtration budget aligned with actual throughput demands. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
