This qualitative filter paper is developed for routine laboratory filtration and separation tasks, suitable for general gravimetric analysis and particle retention in aqueous solutions. It offers consistent porosity and purity to support reliable results in educational, research, and industrial settings. Available in multiple diameters (7 cm to 18 cm, each packaged per box), this model (HZ009) from Canrd provides flexibility for different funnel sizes and experimental volumes. The paper is selected for its balance of filtration speed and mechanical strength, making it a practical choice for everyday qualitative work. Its standard design ensures compatibility with common filtration setups, while the consistent sheet quality minimizes variability across batches.
