TopSpot E Microarrayer

In order to print samples, TopSpot® applies pressure to the liquid filled nozzles.
A piezo stack actuator presses a stamp into the so called actuation chamber of the printhead. The stamp is a piston, which is sealed with an O-ring to the surface of the printhead. When the piston drives down into the actuation chamber, it creates a homogenous pressure pulse that simultaneously affects all the nozzles. If the pressure is high enough, it overcomes the capillary forces of the channels and the surface tension of the fluids in the nozzles. When this happens, the printhead accelerates the fluid and the nozzle dispenses a drop-let. For a better and more homogenous ejection of the droplets, the nozzles area is uniquely coated with a hydrophobic silane.
