Next generation medium-throughput tube-enabled system

  • Enables assay miniaturization in a broad range of applications
  • Ideal for medium throughput applications
  • Accurate, precise, contact-free acoustic transfer in volumes as low as 2.5 nL
  • Transfer from Echo Qualified sample tubes and microplates

The New Sound of Sample Management

The Echo 650T Liquid Handler supports sample transfer directly from Echo Qualified sample tubes, enabling a fully non-contact liquid handling workflow from sample storage all the way to assay ready plates. Capable of transferring as little as 2.5 nL from 384-well and 1536-well microplates, and now, from sample tubes arrayed in a 96-tube format, the Echo 650T Liquid Handler meets the needs of a wide variety of molecular and cellular assays.

Key Benefits

  • Upgrade to increase transfer speed for high-throughput applications
  • Simplified sample screening through direct transfer from Echo Qualified sample tubes
  • Accurate, precise movement of nanoliter-scale quantities, enabling assay miniaturization, further reducing costs
  • Simplified assay development and dilution processes through the flexibility to transfer any volume of liquid from any well to any other well
  • Better results through direct dilution of compounds, an improvement over serial dilution method

Revolutionizing Sample Managementwith an All Acoustic Workflow

from sample store to assay-ready microplates

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

Acoustic Sample Tube Management

The FluidX AcoustiX Sample Tube (FAST) was developed in collaboration with and is sold by Brooks Life Sciences for ultra-high-density sample storage. The acoustic tube offers the following benefits:

  • Echo Qualified design - compatible with Echo 650T and 655T Liquid Handlers
  • Preserves sample integrity from storage to screen
  • Miniaturize upstream liquid handling steps to conserve sample
  • Rapidly pick sets of samples for targeted screening
Icon Automation

Workflow Automation

To meet the broad spectrum of sample throughput needs, the Echo 650T Liquid Handler seamlessly integrates with the highly configurable Access™ Dual Robot System accommodating a wide variety of devices and enabling a fully automated workflow.

  • Configured to achieve optimal throughput for sample management workflows
  • Compact and ergonomic design with docking modules, turntables, retractable shelves, and drawers
  • Optional features can include environmental management to protect samples from hydration or evaporation

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 tubes – 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.
