Overcoming Obstacles In Final Ultra-Filtration Steps

When preparing your pharmaceutical product for the vial, ultra-filtration is the final step in its purification process – just before final bulk filtration. Despite the importance of the end-purification steps and the great challenges that bioprocess engineers must contend with during this phase, there isn’t much literature on the topic. This article explains the careful considerations one should consider when designing the final ultra-filtration steps of a biopharmaceutical product, and how to better ensure that it will meet its required specifications when delivered to the vial.
