Endoscope Washing Filter

Duredunty^® Filter Cartridges

With the development of science and technology, it’s becoming more and more popular to use endoscope for some disease diagnostic and treatment. To avoid cross contamination,endoscope reprocessing is very import but challenging work. And the quality of water is a key element to endoscope reprocessing. It can actually be detrimental to washing, disinfection, sterilization equipment and even causing cross infections between patients if it doesn’t meet the hospitals’ specification. In all the components of the endoscope reprocessing system, the filter cartridge plays an vital role of water purification in the endoscope reprocessing. In the terms of global healthcare guide,it requires that the water used in endoscope reprocessing need to be filtered through a 0.2 micron filter or equivalent quality.

Cobetter offers both prefilter and 0.2μm sterile grade filter in endoscope reprocessing system.Duredunty® is 0.2μm sterile grade filter,which consists of double layer hydrophilic polyethersulfone (PES) membrane. They are especially designed for sterile filtration of a broad of pharmaceutical products and particles, cysts, oocysts, and bacteria in water filtration application, while providing superior flow rates and high bacteria removal efficiency ,longer service time when compare to other sterilizing grade filter.

Features and Benefits

- Double-layered membrane provides great reliability of sterilization.

- Built in asymmetric prefilter layer for longer life and lower filtration cost.

- Broad chemical compatibility (pH 1-14)

- High strength design allows for multiple autoclave cycles (up to 50x) and extended use.

Quality Standards

- Test with B.diminuta (ATCC 19146) at 10⁷-10¹⁰/cm² (>99.99999%)

- Each individual element is integrity tested (bubble point & diffusion flow)

- Each individual elements is traced by serial number
