Grade 114 Qualitative Filter Paper Wet-Strengthened, 90mm Circle, 100/Pk SKU: 1114-090

Qualitative Filter Paper - 1114-090

Teaching laboratories introducing filtration techniques need a paper grade that produces reliable results while remaining cost-effective for student use. Smooth surface finish allows clear visual assessment of retained solids and supports clean separation of precipitates from filtrate. Certificate of conformance documentation accompanies each lot, providing traceability for quality systems and regulatory audit requirements.

Key Filter Paper Characteristics

• Rated at 25um particle retention, the fiber matrix provides a defined cutoff for consistent separation across analytical batches.
• 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.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.

When your application makes the filter paper part of the measurement, the ash and weight specifications above define its analytical contribution. Consistent sheet-to-sheet performance reduces the variability your operators encounter during high-volume daily filtration workflows. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
