Apparatus for producing probe carrier

摘要

An apparatus for producing a probe carrier in which ambient humidity for a plurality of nozzles of a liquid ejection device for ejecting droplets of solutions containing probes to the surface of a carrier is controlled to 50% or more, preferably 60% or more. A part of solution supply passages to the plurality of nozzles is constructed from gas permeable membranes permitting gas-liquid separation under reduced pressure. These gas permeable membrane portions are gathered and altogether placed under reduced pressure to remove air bubbles from the respective solutions supplied to the plural nozzles and decrease the amount of a dissolved gas, which causes air bubbles to be generated.
