Abstract
The invention relates to a method for treating biomaterial using at least one electrical field generated by a first voltage pulse which is terminated once the value for an electrical parameter has exceeded or dropped below a preset limit. After the first voltage pulse has been terminated, it is continued by an additional voltage pulse. The invention also relates to a circuit arrangement comprising at least one storage device for electrical charges to generate at least one voltage pulse by selectively discharging the storage device, and at least one control unit for controlling the discharge. The present invention provides a controller for monitoring the chronological progression of the voltage pulse. This controller controls at least one continuation of discharge after termination.
