About the Sensor Alignment Shelf About this topic The Sensor Alignment Shelf ensures precise positioning of microplates. This topic describes the shelf, which is an Automation Solutions-installed accessory. Description The Sensor Alignment Shelf is particularly useful for 1536- and 384-well microplates where high-precision positioning is essential. The shelf has two built-in sensors that detect the presence of a microplate. During pipetting tasks, the shelf movement actuates three alignment clamps. The clamps position and actively hold the plate during pipetting operations, and then release the plate after the pipetting task is completed. Item Feature Description 1 Actuated clamps Three clamps are actuated by the shelf movement. 2 Sensors Two sensors detect the presence of a plate. About using the shelf Microplates are the only labware appropriate for use on the Sensor Alignment Shelf. CAUTION Before using the Sensor Alignment Shelf, verify that the teachpoint is accurate.
