Bronkhorst High-Tech BV the leaders in Mass Flow Meter / Mass Flow Controller technology for gases and liquids, Pressure Controllers and Evaporation Systems.
Accurately and reproducibly dosing of gases, as oxygen or carbon dioxide, to bioreactors is essential to control the bacterial growth rate. Moreover, for easy scaling-up, a full range of gas flow controllers for different flow rates should be available and be mutually interchangeable.
A benchtop bioreactor has the size of a desktop computer housing, with a reactor vessel of 500 ml and all kinds of sensors. For this system, the customer needed very compact gas flow controllers for low flows. To this end we supplied the IQ+FLOW gas flow controller for one channel, or a package called IQM3 for three channels, to dose the gases (oxygen, nitrogen, carbon monoxide or carbon dioxide) into the reactor. With IQM3 three gases can be dosed simultaneously, each in the range between 10 and 1500 ml per minute.
For this benchtop bioreactor application, a dosing accuracy of max. ±3% is required, which is no problem for the IQ+FLOW flow controllers. These ultra-compact flow controllers have an accuracy of ±1.5%RD plus ±0.5%FS.
In addition to that: if the bioreactor is used for a fixed recipe of gases for bacteria to grow, the composition of the recipe should remain the same over time. Therefore, a good reproducibility is even more important.
Bronkhorst is able to serve the entire biotechnology production range: from lab scale (1 l/min) with the compact IQ+/IQM3 flow meters series, via intermediate scale (20 l/min) with the EL-FLOW Select flow controllers, to full production scale (200 l/min). Upscaling to another instrument with larger flow is easy, as all these devices are available with the ModBus communication protocol.
Nowadays, we not only supply the gas flow controllers for the lab scale bioreactors but also the ones for the intermediate and full production scale equipment.
Bronkhorst High-Tech designs and manufactures innovative instruments and subsystems for low-flow measurement and control for use in laboratories, machinery and industry. Driven by a strong sense of sustainability and with many years of experience, we offer an extensive range of (mass) flow meters and controllers for gases and liquids, based on thermal, Coriolis and ultrasonic measuring principles.
