Next generation high-throughput system
The Echo 655 Liquid Handler supports the highest speed transfer of as little as 2.5 nL from 384-well and 1536-well microplates to meet the needs of high-thoughput biochemical and cell-based screening. As your research needs change, upgrade packages are available that enable the addition of Echo Qualified sample tube capabilities.
Watch the Echo acoustic droplet ejection (ADE) technology in action. Sound waves eject precisely-sized droplets from the source plate onto the destination plate suspended above.
Tipless, non-contact, acoustic fluid transfer of the Echo 655 Liquid Handler eliminates the potential for samples or compounds to adhere to tips. This helps to improve data quality, increasing the potential to find new therapeutics.
In a screen of 975 compounds, Bristol-Myers Squibb found 108 more hits when using the Echo Liquid Handler1.

Set up 384-well cell-based and biochemical assays or transition into 1536-well formats with no loss of performance. The nanoliter volume transfers of the Echo 655 system enables direct dilution of concentrated compounds from sample plates – eliminating workflow steps and keeping the final concentration of DMSO low in the final assay. Data accuracy is further improved through the elimination of compound loss on tips.
