Accurate and stable flow control in microfluidic channels is the basic requirement of microfluidic chip devices for biological research. Control of flow in a micro-channel is necessary for precise manipulation of a sample solution or reagent and for stimulation of cells by mechanical shear force. There are three main types of flow control solutions, which are pressure-based solutions, volume displacement, and passive technologies. Each of them has different advantages. To make the best choice, important considerations include the desired flow rate or pressure range, the speed at which the flow rate is set or changed, and the stability of the flow rate.
Amerigo Scientific offers pressure-based flow control solutions that ensure higher stability and faster responses and can even monitor and control the flow directly with the help of an additional flow sensor.
