The Expansion Channel makes it possible to reduce the minimal working volume to 150 mL in an easy and reliable way without infringing sterility in the bag. This feature is ideally suited to expand a seed culture with less handling and lower costs.
Such way, a culture can be performed in one-and-the-same-bag with working volumes starting at 150 mL up to 15L for microbial and up to 25L for cell culture. Such, simple expansion is possible up to a maximum working volume of at least 25L by using a 3D single use bioreactor bag and a 3D tray. This safes handling, reduces risk for contamination and saves costs (less bags, less equipment needed).
