Chemvast Absolute-Rated Filter Cartridges
Cobetter Chemvast Filter Series
Cobetter Chemvast Filter Series offers a wide variety of PTFE membranes, including hydrophobic PTFE, hydrophilic PTFE, and non-dewetting PTFE. The HDPE cage enhances chemical compatibility, making these filters suitable for most chemical liquid filtration applications. They effectively remove particles from high-purity chemicals used in the semiconductor industry. Available in various retention ratings and pore sizes to meet customer requirements.
The non-dewetting PTFE membrane increases surface energy, ensuring high flow rates and filtration efficiency. With its HDPE cage and high-purity membrane, Chemvast Filters provide a cost-effective alternative to the Chemrapid Filter Series. The hydrophilic PTFE membrane option allows filtration of polar solvents without pre-wetting.
