| Popis: | Centralized high-throughput purification laboratories routinely produce large numbers of test tubes with fractions containing the purified compounds of interest interspersed with test tubes containing fractions collected from undesired peaks. Because the next step after purification entails the removal of the solvent in a centrifugal evaporator with multiple sample positions per rotor, select test tubes must be labeled prior to dry-down to track the identity of each compound. The diversity of test tube sizes and tray configurations from different chromatography system vendors complicates this labeling task. Therefore, the development of an automated tube labeler that can accommodate a multitude of test tube and tray sizes can reduce the chances of error as well as reduce the hands-on labor required to complete this tedious but essential task. Custom hardware and software have been implemented to inform and to enable the Pick-n-Place arm of a commercially available Tecan EVO robotic system to pick up and present select tubes, filled with purified chromatography fractions from a multitude of vendor trays, to a custom label application station integrated with a commercially available Zebra label printer. Particular challenges existed with accurately positioning tubes in Agilent G1364-84544 trays onto the deck of the instrument. The resulting instrument reduces hands-on time for labeling fractions by approximately 60%. |
