Abstract
A novel microfluidic chip is proposed for performing a chemical or biochemical test in a metered reaction volume. The microfluidic chip has a body which defines an inner flow volume. An inlet has been provided to the body for connecting the inner flow volume to the ambient space. A waste channel forms part of the inner flow volume and is in fluid communication with the inlet. A sample channel also forms part of the inner flow volume and is in fluid communication with the inlet. The sample channel includes a first hydrophobic stop and a second hydrophobic stop at a distance from the first hydrophobic stop so as to provide a metered reaction volume there between. An expelling channel is in fluid communication with the metered reaction volume of the sample channel through the first hydrophobic stop. A sample reservoir is in fluid communication with the metered reaction volume of the sample channel through the second hydrophobic stop.
