    • An accurate blending module for adjusting the pH of solutions containing therapeutic proteins includes a recirculation loop that receives the therapeutic protein solution via a feed pump and an acid solution via an adjusting pump. The recirculation loop includes a recirculation pump and a pH sensor that detects the pH of the solution in the recirculation loop. A controller communicates with the pH sensor and the adjusting pump. The adjusting pump adds acid to the recirculation loop based on the pH readings taken by the pH sensor. The recirculation pump recirculates the therapeutic protein solution and acid in the recirculation loop so that it is mixed. As a result, the pH of the therapeutic protein solution is precisely controlled and adjusted in a non-destructive fashion.
    • 用于调节含有治疗性蛋白质的溶液的pH的精确混合模块包括通过经由调节泵的进料泵和酸溶液接收治疗性蛋白质溶液的再循环回路。 再循环回路包括再循环泵和pH传感器,其检测再循环回路中的溶液的pH。 控制器与pH传感器和调节泵通信。 调节泵根据pH传感器采集的pH读数,向再循环回路添加酸。 再循环泵将治疗性蛋白质溶液和酸循环到再循环回路中,使其混合。 结果,治疗性蛋白质溶液的pH被非破坏性地精确地控制和调节。
