picoliter accuracy is impressive!!! What's your precision (dispense coefficient of variation) like? When I was working with automated pipettes, we found that in order get down to single-microliter precision we had to "touch off" on the dispensing surface to use surface tension to pull the last drop off consistently. However, our aspirate/dispense ranges were pretty wide -- around 15uL to about 50mL from the same device.
