ExiGo - iPad mini Microfluidic Pump

ExiGo Microfluidic Pump is a patented, precision, microfluidic, multichannel syringe pump for a variety of microfluidic applications, where accurate and stable flow rate delivery is required. The combination of a high resolution stepper motor drive mechanism, patented pulse damping method and active feedback utilisating flow sensing element has produced a microfluidic pump with superior performance.


Applications:  Microfluidics and nanofluidics, droplet generation and manipulation, pulse-free flow, laminar and multilaminar flow studies, precise multichannel mixing, cell-based shear flow studies, cell and particle manipulation studies.
