The Mohawk tube selector is a semi-automated unit for selecting 2D-bar coded tubes from their storage racks, an ideal solution for many medium-throughput applications such as compound management and biobanking. The system has a built-in operational verification and tractability afforded by linking a Ziath CMOS-camera-based scanner directly to the Mohawk picker. The control interface software allows a rack of tubes to be scanned and decoded so that tubes to be picked by the Mohawk can be identified by their individual bar codes. Once the Mohawk has ejected the tubes from their parent racks, a daughter rack can be assembled manually. This is then verified on the same scanner to ensure that only the correct tubes have been selected from the parent rack(s). Alternatively, the Mohawk tube selector software can use an imported pick list, generated in an Excel spreadsheet, LIMS, or inventory management program, to select which tubes to pick.
