Bioreactor Combines Proven Glass Design and Single-Use Efficiency

Sartorius Stedim Biotech (SSB) has presented the UniVessel SU, the second generation of its successful laboratory bioreactor. This single-use stirred tank bioreactor can be operated in a choice of working volumes ranging from 0.6 to 2 l and is suitable for the cultivation of mammalian cells, including stem cells, insect and plant cells. Typical areas of application for the UniVessel SU are process development and optimisation as well as production of seed cultures and cell banks.

Fast and flexible for efficient management of peak workloads despite challenging timelines, UniVessel SU combines the proven design of conventional glass vessels with the efficiency and flexibility of single-use systems. Supplied as a completely preassembled and presterilised unit, this laboratory bioreactor is instantly ready to use right out of the box. It eliminates the need for labour-intensive steps, such as autoclaving or installation of probes, minimising the time needed for preparation. The new UniVessel SU can be used interchangeably with glass vessels to help laboratories better manage peak workloads despite challenging timelines.

Each UniVessel SU is equipped with integrated single-use sensors for pH and dissolved oxygen measurement. This proven single-use sensor technology, which SSB also uses in its BIOSTAT RM and BIOSTAT STR disposable bioreactors, measures the pH and DO values non-invasively, therefore eliminating time-consuming autoclaving and risk-prone insertion of probes in the culture vessel.

UniVessel SU is compatible with SSB BIOSTAT controllers and can also be operated with nearly any other brand of bioreactor controller. This saves customers from having to buy expensive new equipment. The new UniVessel SU Connection Box enables the integrated single-use sensors of UniVessel SU to be used with existing controllers. Up to four bioreactor controllers can be interfaced per Connection Box. The sensor calibration data can be read in easily by a barcode scanner in an error-free manner.
