Cell Culture Scale-Up in Stirred-Tank Single-Use Bioreactors

The stirred-tank bioreactor design is relatively easy to describe with classical engineering approaches (Figure 1). Parameters to describe this vessel geometry include impeller diameter, vessel diameter, liquid height, and ratios thereof. It is the bioreactor design for which most research on Figure 1: Stirred-tank bioreactor design d D i h ...

Leachables and extractables are defined as substances that can either be extracted from plastic materials under harsh conditions (e.g. extreme temperatures, presence of solvent) or released spontaneously under standard conditions. They may originate from compounds used in polymer manufacturing such as softeners, stabilizers, and antioxidants. Espe-
