A microfludic chip and a method for the manufacture of a microfludic chip

A novel microfluidic chip is proposed for performing a chemical or biochemicaltest in a metered reaction volume (32). The microfluidic chip (100) has a body (200) which defines an inner flow volume. An inlet (10) has been provided to the body (200) for connecting the inner flow volume to the ambient space. A waste channel (20) forms part of the inner flow volume and is in fluid communication with the inlet (10). A sample channel (30) also forms part of the inner flow volume and is in fluid communication with the inlet (10). The sample channel (30) includes a first hydrophobic stop (61)and a second hydrophobic stop (62) at a distance from the first hydrophobic stop (61) so as to provide a metered reaction volume (32) there between. An expelling channel (40) is in fluid communication with the metered reaction volume (32) of the sample channel (30) through the first hydrophobic stop (61). A sample reservoir (51) is in fluid communication with the metered reaction volume (32) of the sample channel (30) through the second hydrophobic stop (62).
