Beckman Coulter ECHO 6XX Acoustic Liquid Handler

Overview

The Beckman Coulter ECHO 6XX is a high-precision, non-contact acoustic liquid handler engineered for nanoliter-scale transfer in demanding life science research and drug discovery environments. Based on piezoelectrically generated focused acoustic energy, the system transfers liquids without physical contact—eliminating the need for disposable tips, nozzles, or syringes. This acoustic droplet ejection (ADE) technology enables true contactless dispensing by generating pressure waves that eject discrete, picoliter-to-microliter-sized droplets from the surface of source wells into destination plates or substrates. The ECHO 6XX operates across standard SBS-compliant microplates (96-, 384-, 1536-, and 3456-well formats), tube racks, slides, agar pads, and custom surfaces—including biosensor chips and glass coverslips. Its core architecture supports seamless integration into automated lab workflows and is widely deployed in genomics, compound management, assay development, and single-cell biology applications where precision, reproducibility, and cross-contamination avoidance are critical.

Key Features

• Non-contact acoustic dispensing eliminates tip-based carryover, surface adhesion, and cross-contamination—ensuring sample integrity across heterogeneous liquid classes (e.g., DMSO, PCR master mix, genomic DNA, RNA, proteins, glycerol solutions, and live cells).
• Automated liquid class recognition: real-time detection of fluid properties (density, viscosity, surface tension) enables adaptive energy calibration—no manual setup or pre-run calibration required when switching between DMSO, aqueous buffers, or viscous reagents.
• True “any-to-any” transfer: supports arbitrary source-to-destination mapping across mixed-format decks—including tube-to-plate, plate-to-slide, and inter-plate transfers between dissimilar well densities (e.g., 384-to-1536 or 1536-to-3456).
• High-fidelity nanoliter dispensing: validated performance at 2.5 nL with ≤8% coefficient of variation (CV) and ≤10% accuracy bias; throughput up to 750,000 discrete transfers per 24-hour cycle under continuous operation.
• Real-time meniscus monitoring and volume tracking: integrated optical sensing captures dynamic liquid surface changes during ejection, enabling closed-loop feedback and post-run traceability.
• Robust, maintenance-light platform: designed for unattended 8+ hour operation; compatible with GLP/GMP-aligned environments through audit-trail-enabled software and electronic record retention.

Sample Compatibility & Compliance

The ECHO 6XX handles a broad spectrum of biologically and chemically diverse samples—including nucleic acids (genomic DNA, cDNA, siRNA), proteins, cell suspensions (mammalian, bacterial, yeast), small molecules in DMSO (up to 100% v/v), glycerol-containing solutions (up to 50%), and complex master mixes (e.g., qPCR, RT-PCR, NGS library prep reagents). All transfers comply with SBS/ANSI standards for microplate geometry and dimensional tolerances. While not intended for clinical diagnostic use (and not registered under China’s NMPA or FDA 510(k)/PMA pathways), the system meets key regulatory expectations for research-use-only instrumentation: data integrity support aligns with ALCOA+ principles; software features full electronic signature capability, user access controls, and 21 CFR Part 11–compliant audit trails. It is routinely validated per ISO/IEC 17025 and ASTM E2500-22 guidance for analytical instrument qualification in regulated discovery labs.

Software & Data Management

ECHO Command Software provides an intuitive, drag-and-drop graphical interface for protocol design, method validation, and run execution. Users define transfer maps visually—including multi-step serial dilutions, reformatting, normalization, and combinatorial mixing—without scripting. Each run generates a comprehensive electronic log file containing timestamped event records, energy settings per well, detected liquid class parameters, and volumetric deviation metrics. Raw data exports support CSV, XML, and SDMX formats for downstream integration with LIMS (e.g., LabVantage, Thermo Fisher SampleManager), ELN systems (e.g., Benchling, Dotmatics), and statistical analysis platforms (e.g., GraphPad Prism, R). Version-controlled method libraries enable SOP-driven deployment across distributed sites, supporting reproducible assay scaling from pilot screening to HTS production.

Applications

• Genomics: NGS library normalization and pooling, amplicon panel setup, qPCR array plating, CRISPR guide RNA titration, single-cell cDNA pre-amplification, and fragment size selection workflows.
• Drug Discovery: High-throughput compound cherry-picking, dose-response matrix generation, ADME assay reagent addition (e.g., CYP450 incubations), phenotypic screening, and stem cell differentiation media formulation.
• Biobanking & Sample Management: Small-molecule library reformatting (DMSO stock → aqueous assay plates), DNA/RNA stock aliquoting, and cryovial-to-plate redistribution with minimal freeze-thaw cycling.
• Structural Biology: Protein crystallization screening via nanodrop dispensing into sitting-drop or hanging-drop plates; ligand-soaking experiments with precise molar ratio control.
• Emerging Modalities: Spatial transcriptomics slide spotting, organoid culture media supplementation, and synthetic biology construct assembly with multi-component reaction setup.

FAQ

Does the ECHO 6XX require tip replacement or cleaning between transfers?
No—acoustic ejection is fully contactless; no consumables (tips, pins, or nozzles) are used, eliminating carryover risk and reducing operational cost.
Can the system handle viscous or volatile solvents like pure DMSO?
Yes—adaptive acoustic energy modulation enables reliable transfer of DMSO (100%), glycerol (50%), and ethanol-based solutions without splashing or misting.
Is method validation supported for regulated environments?
Yes—software includes IQ/OQ/PQ templates, electronic signatures, and audit-trail export compliant with FDA 21 CFR Part 11 and EU Annex 11 requirements.
What plate formats are natively supported?
All SBS-standard formats: 96-, 384-, 1536-, and 3456-well plates; 24- and 96-tube racks; microscope slides; and custom planar substrates.
How is liquid volume verified during transfer?
Integrated optical meniscus tracking monitors real-time surface displacement per well; post-run reports include calculated dispense volumes and deviation metrics relative to target.
Can the ECHO 6XX be integrated into robotic workcells?
Yes—it features standard RS-232, Ethernet/IP, and OPC UA interfaces, and is compatible with major automation frameworks including Hamilton VANTAGE, Tecan Fluent, and Brooks Alpha.
