Lubricants for containers and for conveyors for transporting containers are provided. A first part of the evaporator receives working fluid from the first expansion device at a first pressure, and a second part of the evaporator receives working fluid from the second expansion device at a second pressure that is different than the first pressure. A system includes a grasping device, at least one separate pushing device, and optionally a vertebral spreading device andor a vertebral midline indicator device. The CVD precursor preferentially deposits on the surface of the freestanding film. However, when the high pressure system operates, then the bypass line will be closed by the shunting valve arrangement. The object is achieved by a practice device according to the invention.
