Next generation medium-throughput system

  • Enables assay miniaturization in a broad range of applications
  • Transfer from 384-well and 1536-well microplates
  • Accurate, precise, contact-free acoustic transfer in volumes as low as 2.5 nL

Another Step Forward for Acoustic Liquid Handling

The Echo 650 Liquid Handler is ideal for medium-throughput applications. It enables the transfer of as little as 2.5 nL from 384-well and 1536-well microplates. As your research needs change, upgrade packages are available that enable the addition of Echo Qualified sample tube capabilities.

Key Benefits

  • Measure DMSO hydration levels to gain insights into sample integrity and improve transfer quality
  • Elimination of compound loss, cross-contamination, carryover, or leachates through non-contact transfer
  • Accurate and precise transfer of nanoliter-scale quantities, enabling assay miniaturization, further reducing costs
  • Better results through direct dilution of compounds, an improvement over serial dilution methods
  • Flexibility to transfer any volume of liquid from any source well to any destination well

A Broad Range of Applications

With diverse fluid transfer capabilities and high precision and accuracy, the Echo 650 Liquid Handler supports a wide range of applications in drug discovery and basic research.

Impacting Therapeutic Discovery

Tipless, non-contact, acoustic fluid transfers eliminate the potential for samples or compounds to adhere to plastic 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.

Save Compounds and Money by Miniaturizing Assays

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 655T systems enable 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.

Decrease Cost and Maintain Data Quality

Transition Into High-Throughput Formats

High assay performance at miniaturized volumes enables researchers to move quantitative assays into higher density formats. Assays such as time-dependent inhibition perform comparably to traditional volumes with less reagent, compound, and the elimination of workflow steps.
