Addressing the Demands of High-throughput Screening Labs
The Echo 555 Liquid Handler has the speed and flexibility required for a screening lab. With rapid, highly precise nL volume transfers, Echo 555 Liquid Handler can process over 650* compound and over 500* reagent plates per day. Tasks like plate reformatting, hit picking, daughter plate creation, and adding samples and reagents for screening assays are made easy with the Echo 555 Liquid Handler.
*Based on 100 nL volume transfers
BROAD RANGE of APPLICATIONS
Going beyond DMSO used in high throughput screening, the Echo 555 system supports the transfer of a broad range of aqueous solutions to support high throughput screening laboratories.
Tipless transfer, resulting in dramatic cost savings
Improved information about sample integrity and improved transfer quality through measurement of DMSO hydration level
Elimination of compound loss, cross-contamination, carryover or leachates through non-contact transfer
Extend compound library life through miniaturization of assays
Greatly simplified assay development and dilution processes through the flexibility to transfer any volume of liquid from any well to any other well
The Echo Liquid Handling Technology
Echo Acoustic Liquid Handling|by Labcyte Inc.
The Echo Liquid Handler revolutionizes liquid handling with acoustic energy. Sound waves eject precisely sized droplets from a source onto a microplate, slide or other surface suspended above the source.
Impacting Therapeutic Discovery
Tipless, non-contact, acoustic fluid transfer of the Echo 555 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.

Save Compounds and Money – Miniaturized Cell-based Biochemical Assay
Utilize the Echo 555 Liquid Handler to set up 384-well cell-based and biochemical assays or transition into 1536-well formats with no loss of performance. The nL volume transfers of the Echo 555 systems enable direct dilution of concentrated compounds – 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.

Making High-throughput Combination Screening a Reality
Drug combination screening using the Echo 555 Liquid Handler has revolutionized the approach to the assessment of synergistic effects of drug combinations on disease. The any-well-to-any-well fluid transfer and the Echo Combination Screening application software makes high throughput, 2-way and 3-way dose response matrix studies a reality.
