Abstract: A guiding frame for a laboratory automation device comprises: a bottom side for placing the guiding frame on a component of the laboratory automation device; a top side with a position detection area; and an opening for accessing a port of the component, which opening is arranged besides the position detection area. The position detection area has two recesses, each recess having two straight edges, which from a view direction onto the top side are arranged inclined with respect to each other. The bottom side comprises alignment means for aligning the guiding frame with respect to the component, the alignment means comprising a base surface for contacting a top surface of the component and/or guiding surfaces for contacting walls of the component.
