The Petri Dish Electrodes are designed to be used with a 100mm petri dish which functions as the electroporation chamber. To perform electroporation or electrofusion, the samples are placed in the petri dish and the electrode assembly is lowered into the dish. The electrode assembly is available in 2mm gap sizes. They contain parallel stainless steel electrodes, which produce homogeneous fields. The electrodes are designed to electroporate volumes ranging from 10 to 50 ml. The 2mm gap Petri Dish Electrode can be used for electroporation of tissues grown right in the petri dish. Simply add the exogenous molecule of interest, mix and electroporate.
