I feel compelled to leave a strong recommendation for potential purchasers of the Mantis. We have now implemented the Mantis into our everyday workflow for assay development. The software is easy to use and allows us to quickly set up DOEs with varying concentrations of reagents and directed to appropriate wells. We have also been extremely efficient in showing the feasibility of smaller volume reactions using the Mantis, with several assays moving from using the higher volume diaphram to the smaller volume diaphram and decreasing the size of reaction from 5uL to 500nL - huge cost savings!!!! Plus money we save from not losing valuable reagents is also a huge plus, the low dead volume alone makes this a great purchase. We give the Mantis our highest recommendation.
