Abstract (en)

[origin: WO2021259497A1] The present application relates to a microfluidic chip for a biological or medical staining or assay. The microfluidic chip comprises a base plate with a first main side and a second main side, a reaction chamber which is open towards said first main side, means for affixing a slide on said reaction chamber in a fluid-tight manner, at least one first channel connecting at least one input opening with the reaction chamber and at least one second channel connecting the reaction chamber to a waste. The at least one first channel comprises at least one solution in a quantity which is sufficient to carry out the staining or assay in the reaction chamber. Further, the present application also relates to a pumping device comprising a seat for a microfluidic chip as described above and a pump. The seat is configured such that at least one outlet of the pump is connectable to at least one input opening of a microfluidic chip arranged in said seat in order to pump a fluid into said at least one input opening by means of the pump.
