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.
