Abstract
Integrated microfluidic valves enable automated control in microfluidic systems as they can be applied for mixing, pumping, and compartmentalisation purposes. However, many organ-on-chip systems require channel dimensions in the range of hundreds of micrometres while the typical fabrication process for normally open micro valves requires a reflow photoresist which is not capable of achieving these dimensions. Here we show a mechanical macro valve, fabricated cleanroom-free by micromilling, closing and bridging a 400 μm high, 1000 μm wide channel. Furthermore, we use the valves to create an inlet switch and a peristaltic pump with a pumping rate of 2 μL/min.
