Features
- Excellent retention ability
The cellulose media of the Claricap CSD & Roheap CSD series filter are intertwined to form a compact three-dimensional porous structure, with gradient pore size that can efficiently trap particles during the filtration process.
The activated carbon powder treated with phosphoric acid or water vapor carries ultra-high specific surface area and is very effective in decolorization and the removal of other contaminants.
The filter medium sheets also include a small amount of special synthetic resin, which improves the wet strength of the medium sheet and makes the filter sheet positively charged to increase adsorption efficiency.
- Excellent Operational Performance
The cardboard is made of high-purity bleached cellulose, which greatly reduces the extractable metal ions and endotoxins content, making the Claricap CSD & Roheap CSD series filter more suitable for use in biopharmaceutical and other high-purity applications. Thanks to its internal cellulose three-dimensional structure and high activated carbon content, the filter has ultra-high dirt holding capacity and decolorization ability.
