"This is a reliable contact dispenser, which can dispense accurately from 2ul or higher. This system works for 384 well plate and 1536-well plate, which need transfer from 384-plate as a source plate. The percentage CV is usually about 5% or less. We routinely use it for reagent addition. For compound addition, we use it for transfer from serially diluted compound sourcing plate. The down side compared with non-contact dispenser is that the tip cost is a concern for high throughput screen. At a recent exhibition, I note that there are some new features made to this liquid handler. These include 1536-well head, which eliminates the needs for transfer for 1536-well plate stamping or transfer. Also, the plate tower for housing the plates has increased by more than 2-fold. These are unique features and I cannot wait to try it out. Based on my years of experience, I would recommend this product to a colleague and I would encourage them to get the newer versions."
