Patent ID: 7923238

Claim:
An electroporation system capable of providing an electrical pulse to one or more samples, the electroporation system comprising: a capacitance; a charging circuit configured to charge the capacitance; a first electrical connector adapted to connect with a common pad of a sample plate having a plurality of banks, each having a plurality of wells, wherein when the first electrical connector is connected with the common pad, the first electrical connector is connected with a first electrode of each well of the banks; a plurality of drivers, each adapted to connect with one of a plurality of separate pads of the sample plate, wherein when a driver is connected with a separate pad, that driver is connected with a second electrode of each well of one bank, wherein a state of that driver determines whether an electrical pulse is transmitted from the capacitance to the one bank connected with that driver; and a control processor configured to: prior to transmitting the electrical pulse from the capacitance to a bank, determine a resistance of a sample in the wells of the banks; based on the determined resistance, select one or more banks for delivering an electrical pulse from the capacitance; and control the state of the drivers such that the electrical pulse is transmitted to the selected banks, wherein prior to the selection of the one or more banks to send the electrical pulse, the control processor is configured to determine a number of banks to be selected based on: an operating range of one or more circuit components of the electroporation system that are used to provide the electrical pulse to the selected banks; and the determined resistance, wherein the number of banks is variable, and wherein the possible values for the variable number of banks include one bank and a plurality of banks.
