GEPES-Series Electric Grade Polyethersulfone
GEPES-Series High Purity Electronics Grade Polyethersulfone Filter Cartridges meet the stringent requirements of cleanliness of the microelectronics industry.
GEPES-Series Overview
GEPES-Series High Purity Electronics Grade Polyethersulfone Filter Cartridges meet the stringent requirements of cleanliness of the microelectronics industry. The polyethersulfone membrane offers high flux density and provides superior throughput for extended operating life. Cartridges undergo extended flushing with 18 megaohms of ultra-high purity water to achieve extraordinarily low levels of extractable substances. Each element is integrity tested for optimized, highly consistent performance. Manufactured in a clean-room environment to maintain high standards of purity and cleanliness.
