GE Healthcare offers a wide choice of qualitative cellulose filter papers with different levels of purity, hardness, flow rate, loading capacity, and chemical resistance. Two formats are available: standard filters and wet-strengthened filters. Some standard and wet-strengthened filters are available in pre-pleated forms which improves flow rate and increases loading capacity compared to equivalent flat filters.
Whatman qualitative filter papers are manufactured from high-quality cotton linters, ensuring quality, reproducibility, and uniformity. Qualitative cellulose filters are used in qualitative analytical techniques to determine and identify materials. A wide range of retention/flow rate combinations matches numerous laboratory applications.
