Pharmaceutical
We have the expertise to help in scale up, process development (in terms of mixing performance), and design for cGMP installations. Our background in the production of active pharmaceutical ingredients allows us to differentiate between mixing theory and practice for successful operation in manufacturing operations. Proper mixing is critical to both homogeneous and heterogeneous reactions either in achieving the desired conversion rate and in achieving the predicted selectivity.
