    Thermo Scientific Multidrop Combi
    "We run a core facility with numerous users and generally we like this instrument. It replaced our Matrix WellMates, and is a little faster dispensing, and somewhat more intuitive to use. It also has the ability to dispense a lower volume, although when we tested them head-to-head the WellMate was the better dispenser that day. Dispensing accuracy and precision greatly depend on the manifold/cassette you are using. The Combi cassettes are much more expensive than the WellMate manifolds and do not seem to be as durable. We have had numerous occasions where a piece of tubing has separated from the dispensing nozzle inside the cassette, and despite much effort to reattach them, it never seems to work again. The cassettes come in differing sizes (small and standard) and there are limitations with the standard cassettes in that they only dispense in multiples of 5uL. We have also noticed that the apparent dispense speed is higher which will result in bubbles forming in the well if you are dispensing high % serum media (15-20%). There is no ability to set a priming a volume. You have to hold the prime button. And if you set the dispensing options, and then go into the program menu, it switches all of your choices even if you do not choose a program. Do I like it? Yes, it's okay, but I would compare with other options and really go with what works best for you."

    "The Acumen is highly effective at getting us the results that we want and is fairly easy to use once a protocol is set up on the instrument. The only issues that I have with it are that some of the functions of the software are harder to find than I believe necessary (e.g. how to tell how many cells are in each well while that program is running) and that the machine is very finicky in the fact that if anything in the machine is bumped or a little loose it can make the whole program go down. Other than that, the support is great (my emails are always answered within 24 hours) and for the most part the machine runs pretty smoothly."
