A device for carrying out microfluidic reactions comprises a reaction chamber (30), a fluid duct communicating (10) with said reaction chamber (10) including a hydrophobic region (20) and a pressure control element (50) for applying a predetermined pressure toliquid in the duct (10) in response to a suitable signal. The duct and reaction chamber are provided on a silicon microchip, whilst the pressure contrl element (50) is provided externally. |
