A manufacturer of microfluidic systems was looking for a flow solution to measure micro fluids more efficiently. At the start of their search, thermal mass flow meters were used. However, they observed that the thermal mass flow measurements in their application were too unstable and could not be reproduced. Bronkhorst suggested an alternative solution, using Coriolis technology for the microfluidic flow meter.
In microfluidic systems, liquids behave in a different way compared to flow in ‘normal’ channels. Due to the small size of the channels, the ‘fluid-wall’ phenomena play a dominating role. Microfluidic devices find their application in fields such as pharmaceutics and biotechnology, reducing the number of chemicals and experimental time.
For this application, the microfluidic systembuilder desired to limit the number of flow instruments by simplifying the solution. In the consisting setup, five mass flow meters were used to cover a specific flow range. A second wish was to improve the accuracy and repeatability of the measurement itself.
Looking at the user’s needs, Bronkhorst concluded that the ML120 mini CORI-FLOW flow meter series would be able to cover the entire microfluidics range needed. The idea was to test this Coriolis flow meter and to compare the results with the ones from the thermal flow meter. During two months the ML120 device was test thoroughly.
The test results stated that using the Coriolis-based flow meter the accuracy, stability and repeatable where better then the original setup with thermal flow meters. Moreover, the results showed that is was possible to replace five thermal mass flow meters bij one Coriolis-based flow meter (ML120 mini CORI-FLOW series) with a large dynamic range to cover the same range. Not even was the test succeful, but the customer integrated the ML120 device in their product range as well.
As part of further cooperation with Bronkhorst, the microfluidic system builder developed a user guide for (future) users and a selling guide for the sales engineers. Moreover, some programming work in LabVIEW is performed to communicate with Bronkhorst devices.
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.
