for medium throughput screening and large genomics projects

  • Most diverse range of applications in the Echo Liquid Handler family
  • Impacts all phases of drug discovery process
  • Saves money and increases data quality in large genomics projects

Impacting Science with Sound

Acoustic liquid handling is changing how researchers are doing science. The precise nL transfer volumes, the any-well-to-any-well transfer capability, and flexible applications software of the Echo 550 Liquid Handler enables researchers to set up experiments not possible with traditional liquid handling.

Key Benefits

  • Better information about compound integrity and improved transfer quality through measurement of DMSO hydration level
  • Eliminates sample and compound loss, cross-contamination, carryover or leachates
  • Accurate, precise transfer of nanoliter-scale increments, enabling assay miniaturization, further reducing costs
  • Better results through direct dilution of compounds
  • Simplified assay development and dilution processes through the flexibility to transfer any volume of liquid from any well to any other well

A Broad Range of Applications

With a combination of high transfer speeds and diverse fluid transfer capabilities, the Echo 550 Liquid Handler supports a wide range of applications in drug discovery and basic research.

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.
