The Immediate Drop on Demand Technology (I.DOT) is a new approach for non-contact low volume dispensing, developed at the Fraunhofer Institute for Manufacturing Engineering and Automation IPA, Stuttgart, Germany. The Artel Multichannel Verification System (MVS) was used during the development of the I.DOT Non-contact Dispenser and is now utilized at Dispendix GmbH, Stuttgart, for quality control of the series systems. In this Technical Note we provide typical data for inaccuracy and imprecision for the I.DOT One dispensing platform utilizing the Artel MVS. The results for single channel and multi-channel operations were all within the specification of the I.DOT system. These results demonstrate that the I.DOT One can produce both accurate and precise non-contact liquid transfers while providing a highly flexible platform in terms of throughput, volumes and liquids.
In this study, Artel´s MVS has been utilized to provide data for imprecision (% coefficient of variation) and relative inaccuracy (% systematic error) for the I.DOT One non-contact liquid handling system. The data presented in this Tech Note are typical for the I.DOT and can be expected from optimized protocols. The MVS system is an exceptionally helpful system for developers and suppliers of liquid handling systems to optimize the dispensing performance already during development, production, and final testing. In summary, the results generated by the MVS clearly show that the I.DOT One system meets or exceeds all of Dispendix’s specifications for both relative inaccuracy and coefficient of variation.
