Air bubbles in a liquid sample are a major problem in numerous microfluidic experiments. That is why the engineering team from Bartels Mikrotechnik developed a solution: the mp-bt bubble trap removes air bubbles from a microfluidic system. Anja Blase, engineer at Bartels Mikrotechnik, says about the mp-bt: “Our goal was to build a bubble trap that is small, cost-effective and easily integrated into fluidic systems.”

The issue with air bubbles in microfluidic systems

When transporting fluids, air bubbles lead to a fluctuation in flow and pressure rates. Additionally, volume sampling errors are likely and the components can experience a decrease in performance: sensors dry up or chips do not work properly. 

On top of that, air bubbles introduce oxygen to the system. This can lead to cytotoxicity, the damage of the biological sample. The main task of bubble traps is the in-line removal of those air bubbles. It protects experiments and helps the overall performance of the system.

All new: the mp-bt bubble trap

At the end of 2021, the company launched their very own bubble trap. The mp-bt is smaller compared to other traps currently on the market. The mp-bt is a component that only needs to be connected via regular tubing. Then, the user connects a mp6 micropump to the bubble trap which creates a vacuum that sucks the air in the flow stream through the hydrophobic membrane in the trap. This ensures optimal performance.
