The company has added hydrophilic PTFE filters to its expanding line of cartridge filters for bulk high-purity chemicals used in microelectronics manufacturing, including LCD, semiconductor, hard disk drive and photovoltaic. The filters can be used as drop-in replacements for existing filters to achieve significant flow improvements while maintaining or increasing particle retention. This dramatically increased performance can provide a retention upgrade while maintaining system flow, reducing processing time, or decreasing the number of filters required for a lower total cost of ownership. The new filters incorporate the company’s proprietary high-flow hydrophilic PTFE (polytetrafluoroethylene) filtration media, which does not require IPA (isopropyl alcohol) pre-wetting and completely eliminates de-wetting issues in most applications. They are well-suited to filtration of aqueous and high-surface-tension liquids, especially where outgassing or bubbles are a concern. Applications include high-throughput filling, packaging and recirculation systems.
