FAQ
A stirred tank bioreactor consists of a vessel with a defined height dimension ratio. Mixing is achieved through a central stirrer element inside the culture vessel. The stirrer is driven by a motor packed on the head plate. Furthermore there are multiple ports in the head plate that have different functionalities like probe insertions, substrat addition and gas insertion as well as the removal of samples.
They are small-scale bioreactors with volumes from 1 to 10 L. These bioreactors are often used in research labs. They are available with autoclavable multi-use glass vessels or single-use vessels. Depending on the system configuration, they allow for similar process control as their large scale counterparts and can function as scale-down models for large commercial processes.
The benchtop bioreactor has a small footprint and fits on a lab bench. It could be equipped with single-use or multi-use vessel. The multi-use Univessel® Glass is available as single-wall or double-wall vessel. A benchtop bioreactor can be used to run batch, fed-batch or perfusion processes.
Stirred-tank bioreactors are well known for excellent scalability, as constant height to diameter ratios and vessel diameter to impeller diameter ratios can be achieved. The central stirring element leads to optimal mixing of nutrients and gasses inside the culture vessel. This allows scalability which results in reduced time and effort for process development.
