ELECTROPORATION CELL WITH ARC PREVENTION OR REDUCTION

摘要

An electroporation system and method for directing high-voltage currents to a suspension of cells contained in a cuvette. A high-voltage switch controls t he coupling of a charge control to a high-voltage capacitor and, additionally, controls the coupling of the high-voltage capacitor to the cuvette. A curren t diverter diverts current away from the sample whenever an arc condition commences or a low sample resistance is detected across the cuvette. The current diverter includes a current diverter switch, which is triggered when a sense resistor measures a second predetermined voltage indicative of an arc- over event (or a low sample resistance condition).
