Single-use, high flux dialyzer with a polypropylene housing and polyethersulfone membrane. More homogenous pore sizes, resulting in better clearances of uremic toxins and low molecular weight proteins like ß2-microglobulin and myoglobin, with limited loss of important proteins such as albumin. Unique ripple structure inside the dialyzer creates a more homogenous flow, enhancing small molecule clearances. Ultra-smooth polyurethane cut surface minimizes the risk of blood cell damage and clotting, resulting in better rinseback to patients. Improved header shape with redesigned caps to optimize blood flow dynamics. Header caps are permanently attached, eliminating accidental removal or reuse.
