Microejector pump

摘要

A microejector pump for generating microdrops includes at least one pump chamber configured in a silicon chip and a piezoelectrically actuable silicon membrane arranged over the pump chamber. The pump chamber is connected to at least one supply line as well as a discharge line provided with an ejection orifice. A glass chip closes off at least the pump chamber from the silicon membrane. The microejector pump can also include an integral heater and controller.
