Abstract: A laboratory automation apparatus with a liquid volume measurement functionality comprising a working table, a pipettor comprising a pipetting head with an electrode providing a capacitive sensor with a reference electrode. A robotic arm is configured to move the pipetting head above the working table. A processor is operatively coupled to the robotic arm, to the pipettor and to the electrode by an electronic circuit. A capillary is located on the working table having an opening for receiving a target amount of liquid from the pipettor to form an air-liquid meniscus in the capillary. The robotic arm is configured to hover the electrode over the capillary to detect a change in capacitance related to the position of the meniscus, and the processor is configured to calculate the transferred amount of liquid from the position of the meniscus in the capillary.

Abstract: The invention relates to an above-ground storage tank having a leakage protection lining for storing media posing a hazard to water, and to a process for equipping and particularly refitting an existing above-ground storage tank with a lining protecting it against leakage. The lining can be mounted permanently and vacuum tight on the walls of the tank. A medium-resistant foil almost completely covers the tank bottom and extends up into the lower zone of the inner side of the tank wall. This foil is secured around the outer limitation of the tank bottom by a clamping device. An insert covers the tank bottom and extends up to the clamping device.
