Bronkhorst High-Tech BV the leaders in Mass Flow Meter / Mass Flow Controller technology for gases and liquids, Pressure Controllers and Evaporation Systems.
Bronkhorst offers gas flow control for bioreactor manufacturers and has a gas flow controller available especially for use in benchtop bioreactors. This flexible instrument has a wide dynamic range allowing the bioreactor manufacturer for easy change of flow range and switching to other gas types with one instrument. This way you can benefit from model reduction, allowing you for local stock and therefore, independency of lead times.
Most bioreactors, whether they are used for fermented food and drinks or development of vaccines and medicines, need to be supplied with gases for growing bacteria, yeast or cells for the desired biological synthesis to take place. These gases are usually added continuously over a period of a few days to several weeks using flow controllers.
For a reliable biological growth process, accurate, repeatable, and stable gas flows are essential. Especially in the R&D environment, a wide range of gas flow rates is necessary to investigate the best growth conditions. For benchtop bioreactors compact gas flow instruments are desired. For manufacturers that build bioreactors on specification for customers, it is desirable to reduce the number of variations of flow instruments, to counteract obstacles in delivery time. Moreover, pressure data is desired to inform the bioreactor user about the current process conditions.
Due to a capillary chip sensor technology combined with friction-free valve technology and electronics, the FLEXI-FLOW instrument has an excellent accuracy, repeatability and long-term stability. The capillary chip sensor that measures the gas flow remains very stable over the years and does not need calibration. Since the small sensor is less prone to temperature gradients, the short-term stability is very good as well.
Pressure information is desired to inform or alarm the bioreactor user. This accounts for gas supply pressure at the inlet and bioreactor process pressure at the outlet. Limitation of the process pressure is necessary for bioreactors to avoid breakage of the reactor. The FLEXI-FLOW gas flow controller contains pressure measurement and control at the inlet and outlet of the instrument, and as such, this smart instrument is suitable for predictive maintenance of the bioreactor system.
