The New Sound of Sample Management

Due to their outstanding throughput, high transfer accuracy and precision down to nanoliter volumes and any-well to any-well transfer capabilities, Echo Liquid Handlers have long been integral to state-of-the-art sample management and high throughput screening solutions.

Offering these same benefits, the Echo 655T Liquid Handler now supports sample transfer directly from Echo Qualified sample tubes enabling a fully non-contact dispensing 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 acoustic tubes arrayed in a 96-tube format, the Echo 655T Liquid Handler is ready to meet the needs of a wide variety of biochemical and cellular assays.

Echo 655T Liquid Handler

Key Benefits

  • Fastest dispense rate from an acoustic sample tube
  • Simplified compound library screening through direct transfer from acoustic sample tubes
  • Elimination of compound loss due to adhesion to or contamination from tip plastic through non-contact transfer
  • Minimized DMSO hydration through environment controlled transfer zone
  • Supports 384-well and 1536-well microplates in addition to new acoustic sample tube

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:

  • Improved sample integrity through unique cap design – internal cap seal and increased cap/decap cycles enables longer term sample storage and enhanced sample access
  • Random access to any stored sample minimizing freeze/thaw cycles
  • Echo Qualified Tube design and manufacturing – compatible with Echo 650T and 655T Liquid Handlers
  • Working volume of 15-85 µL and 20-90 µL with DMSO and aqueous fluids respectively

Workflow Automation

To meet the broad spectrum of sample throughput needs, the Echo 655T Liquid Handler seamlessly integrates with the highly configurable Access Dual Robot System accommodating a wide variety of devices and enabling a fully automated workflow. Whether your workflow requires plate reformatting, hit picking, daughter plate creation or adding samples and reagents for screening assays, Labcyte offers a fully integrated Echo 655T Liquid Handler solution to meet your needs.

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 655T 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 655T 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 655T 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.
