If you look at the tech specs (can be donwloaded from the BD website)
the max analysis rate for 8 par is 70K/sec;slower if more parameters.
Sort rate (70 psi, 90 kHz drop drive) at 25K/sec, 98% purity, 80% of
poisson theoretical yield.
I think that the sort rate has been confused with the analysis rate
(perhaps even by BD).
You can sort faster than the spec, but the yield will drop.
