Membrane filter elements CF - series (version B) Pleated polyethersulfone (PES) membrane filter elements with support frame and end caps made of polypropylene. All components are thermoplastically welded to one another. The operating temperature is max. 80°C. The elements are suitable for the safe retention of bacteria. All materials used in production meet the requirements of the FDA and are approved for contact with food. The elements can be steamed several times (135°C and 30 minutes) and sanitized (85°C and 30 minutes). They are pre-rinsed with DI water. (For more information, see product sheet 1.351) CF - series (version E) Pleated polyethersulfone (PES) membrane filter elements with support frame and end caps made of polypropylene. All components are thermoplastically welded to one another. The operating temperature is max. 80 ° C. The filter elements can be used for up to 30 minutes in DI water at 95 ° C. By flushing with 12 liters of ultrapure water with a flushing time of <30 minutes per 10 "element, a conductivity resistance of 18 MΩ is achieved. Each element is serially tested for integrity. The elements are specially developed for the semiconductor and electronics industry.
