"I was upgraded to an Aria IIu several years ago. The upgrade was a great investment, greatly improving the performance of the instrument. However, this is an instrument that requires an experienced and well trained operator. It is not a high speed sorter if referenced against a MoFlo, but is much improved on the Vantage. As a rule of thumb the sample speed should be 1/5 of the frequency. In my hands the Aria IIu works best with a 85um nozzle, ~45,000 droplets/sec and a sample speed of <9,000 events/sec, at a sheath pressure of 45psi. My local service & support is superb."
