Abstract: In one embodiment of the present invention, an electromagnetic drive unit including a coil, a yoke, and an armature is disclosed. The winding of the coil is partly wound in one direction and partly in the other direction. An electromechanical switching device includes at least one input terminal and a respective output terminal and an electromagnetic drive unit adapted to limit or to break the electrical current between the at least one input terminal and the respective output terminal.

Abstract: A device and method that enables the reliable and reproducible testing of the cleaning efficiency of an ultrasonic cleaning device is disclosed.

Abstract: The invention relates to a microtiterplate appropriate for long-term storage of a high number of compound solutions. The invention more specifically relates to a microtiterplate for long-term storage, comprising: a) a frame (10) supporting: i) a matrix of wells (11) presenting a top surface, ii) liquid-receiver peripheral chambers (20) surrounding the matrix of wells, iii) a groove (16) peripheral to the liquid-receiver chambers, being defined by inner and outer side walls, and, b) a cover (30) for enclosing the matrix of wells and liquid-receiver peripheral chambers, said cover comprising at least one protrusion which releasably engages into the groove, characterized in that the top of the inner and outer side walls of the peripheral chambers are in close contact with the cover, and the top surface of the matrix of wells is not in close contact with the cover, thereby defining a closed single space between the top surface of the matrix of wells and the cover.
