Abstract
Chamber for treating cells contained in a suspension in the electrical field with a beaker made from electrically non-conductive material, into which an elongate core made from electrically non-conductive material is at least partially inserted axially through an opening, between the beaker and the core a gap being present to receive the suspension; at least two electrodes made from electrically conductive material arranged on the outer face of the core facing the gap, between which an electrical field can be created to treat cells in a suspension contained in the gap by applying a voltage; the thermal expansion coefficient of the material of the electrodes and of the material of the core being matched with one another such that the electrodes do not substantially alter their position relative to the core in the temperature range from ambient temperature to temperatures reached during autoclaving and/or sterilising.
