METHOD AND DEVICE FOR CONTROLLING THE FILLING LEVEL IN A CHAMBER
The invention relates to a method and device for controlling a filling level of a suspension of cells, cell derivatives, organelles, sub-cellular particles and/or vesicles within at least one chamber of a device for applying an electric field to the suspension. In order to avoid overfilling of the c...

| description | The invention relates to a method and device for controlling a filling level of a suspension of cells, cell derivatives, organelles, sub-cellular particles and/or vesicles within at least one chamber of a device for applying an electric field to the suspension. In order to avoid overfilling of the chamber if multiple electroporation cycles are performed and to achieve exact filling in an environment of unpredictable chamber volume, the amount of suspension filled into the chamber is dynamically limited in the course of several electroporation cycles by determining at least one change of the electrical resistance at the outlet port. The resistance between at least one electrode and a grounding electrode is measured during the filling procedure of each cycle at several points in time. Once a change of resistance is detected, the termination routine is initiated and the filling procedure is finally terminated. Exact filling of the chamber is thus ensured during each electroporation cycle so that enhanced reprodu |
