The present invention relates to a method for determining the position of a robotic arm in an automatic liquid handling system in which a measurement probe with a first electrode is arranged on the robotic arm and, together with a second electrode formed by at least part of a working area or at least part of a container or container carrier forms a measurement capacitor that is operatively connected to a measurement unit for measuring an impedance, in particular a capacitance of the measurement capacitor. The method involves moving the measurement probe along a first path, detecting a first change in the impedance, in particular in the capacitance of the measurement capacitor at a first point on the first path, and defining at least one first reference spatial coordinate for a control unit of the robotic arm on the basis of the first point on the first path.

A worktable for a laboratory automation system can include a worktop with a level surface and a support profile for supporting the worktop, bent from a metal sheet The support profile can include a facing edge, and an underside of the worktop can lie directly on the facing edge. The support profile can include at least one reception lug. The worktable can include a bolt-shaped fastener for attaching the worktop on the support profile. The bolt-shaped fastener can project through the worktop and be received in the reception lug.

Laboratory table with front and opposite rear frame parts, has replaceable tabletop elements positionable thereon. In a first variant, the laboratory table further has detent openings at regular distances on the front and/or rear frame parts, defining a modular grid. Each opening can receive a detent bolt of a modular tabletop element, each element having at least two detent bolts for the insertion into one of the detent openings. In a second variant, each tabletop element has at least one detent opening on a front and/or rear side of the tabletop element, for insertion of a detent bolt. The front and/or rear frame part of the laboratory table have detent bolts arranged at a regular distance defining a modular grid, each one of the detent bolts being for insertion into one of the detent openings of the tabletop elements positioned on these front and rear frame parts.
