The Gemini Twin Wave Electroporators are flexible systems allowing both square wave and exponential decay wave electroporation in a single unit. These waveform combinations enable researchers to easily and efficiently electroporate eukaryotic and prokaryotic cells in cuvettes or plates with one easy-to-use setup. Prokaryotic cells typically respond well to exponential decay wave pulses and eukaryotic cells are transfected most efficiently with square wave pulses. Combining these two waveforms gives researchers total flexibility to achieve the highest efficiency for their applications.
