Guide and selection support
Bioreactors serve the controlled cultivation of microorganisms, cell cultures, or small plants for biotechnological processes and productive applications. They enable the regulation of environmental parameters such as temperature, pH, and oxygen supply to create optimal growth conditions.
When choosing a bioreactor, factors such as cultivation volume, type of organism to be grown, degree of automation, and requirements for process parameters are relevant. The type of construction—such as stirred or flow reactors—and material compatibility also play a role.
LabFinder supports targeted searches for bioreactors by organizing the category clearly by application area and technical features. This allows users to find suitable reactor systems tailored to various biotechnological requirements.
Applications and Benefits
A bioreactor is a closed vessel in which microorganisms, cells, or small plants are cultivated under defined conditions. The technology supports biotechnological processes such as fermentation as well as bioconversion and biocatalysis. Bioreactors are used in research, development, and production to selectively multiply biological materials, produce metabolites, or maintain cell cultures.
Selection Criteria
Typical criteria for selecting a bioreactor are volume, controllability of process parameters (temperature, aeration, stirring, pH), mechanical properties, and vessel material. The type of organism or cells (bacterial or eukaryotic) as well as the complexity of the technical-biological process influence the appropriate reactor design. Automation and monitoring functions can also be taken into account.
Variants and Measurement Principles
Bioreactors are available in various designs, including stirred-tank reactors, bubble columns, and flow reactors. The choice depends on requirements for mixing, oxygen supply, and process control. Integrated sensors can measure parameters such as dissolved oxygen, pH, and redox potential to optimally control the cell cultures.
Calibration and Maintenance
Regular maintenance and calibration of sensors and control systems are necessary for reliable process control. Cleaning and sterilization of reactor vessels are important to prevent contamination and ensure reproducible cultivation results. Service intervals depend on the model and operating conditions.
Application Limits
Bioreactors are designed for biological systems; therefore, their use is mostly limited to the cultivation of living organisms and biochemical processes. Other methods may be more suitable for heterogeneous or highly solid substrates. The scalability of bioreactors is limited by both technical and biological factors.

Frequently asked questions
How does a bioreactor work?
A bioreactor enables the controlled cultivation of microorganisms or cells by regulating environmental parameters such as temperature, pH, oxygen supply, and stirring to provide optimal conditions for biological growth processes.
What types of bioreactors are there?
Common types include stirred-tank reactors, bubble columns, and flow reactors. They differ in their mixing methods, oxygen transfer, and suitability for specific organisms or processes.
What should be considered when selecting a bioreactor?
Key factors are volume, controllability of process parameters, compatibility with the organisms to be cultured, degree of automation, as well as material and maintenance requirements.
How is the quality and function of a bioreactor ensured?
Reliable process conditions are maintained through regular calibration of sensors, maintenance of control units, and careful cleaning and sterilization of reactor surfaces.
What are the limitations of bioreactor applications?
They are mainly suited for the cultivation of living cells and microorganisms; highly complex solid materials or non-biological systems usually cannot be processed efficiently. Scalability is also limited by technical and biological factors.
