Failure of the first, coarse leak detection stage, e.g. pressure-course a or impedance or laser-absorption based leak detection stage, causes containers to be rejected together with their corresponding container holders. These are then separated, and the contain­ er holder is cleaned and dried before being returned to the system. Any leaking product from inside a grossly leaking container is thus retained within the container holder, thus reducing contamination of subsequent containers and their container holders, prevent­ ing such contamination from reaching the fine leak detection stage, e.g. mass-spectrometer-based a leak detection stage.
