Eppendorf epMotion 5075l Automated Liquid Handling Workstation

Overview

The Eppendorf epMotion 5075l is a high-precision, fully automated liquid handling workstation engineered for reproducible, walk-away pipetting in demanding life science laboratories. Built upon Eppendorf’s proprietary positive-displacement and air-displacement pipetting technologies—calibrated per ISO 8655 and traceable to national standards—the system delivers sub-microliter accuracy across its full operational range (0.2 µL to 1,000 µL). Unlike semi-automated platforms, the epMotion 5075l integrates coordinated motion control, real-time liquid level sensing, and adaptive tip recognition to minimize variability from viscosity, volatility, or surface tension effects. Its modular architecture supports end-to-end assay automation—from reagent dispensing and serial dilution to plate replication and normalization—making it suitable for applications requiring strict adherence to GLP, GMP, and FDA 21 CFR Part 11 data integrity requirements.

Key Features

• Fifteen ANSI/SLAS-compliant deck positions enable flexible configuration of source plates, destination plates, tip racks, reservoirs, and auxiliary modules—including up to three independently controlled temperature modules (0 °C to 110 °C) for precise thermal management of samples and reagents.
• Automated tool changer supports seamless switching between single-channel, 4-channel, and 8-channel pipetting heads without manual intervention—ensuring optimal channel utilization and minimizing cross-contamination risk.
• Integrated optical liquid level detection identifies meniscus position in real time, automatically adjusting aspiration/dispense parameters to maintain volumetric fidelity across diverse liquid classes (e.g., glycerol-rich buffers, ethanol-based solutions, or low-volume aqueous suspensions).
• Universal consumable compatibility includes tubes ranging from 0.1 mL PCR tubes to 50 mL conical centrifuge tubes, as well as all standard microplate formats up to 384-well, with automatic barcode reading capability when equipped with optional scanner module.
• epBlue software suite—preinstalled on the MultiCon industrial PC—provides intuitive touchscreen or mouse-driven workflow design, drag-and-drop protocol building, and real-time execution monitoring with full audit trail logging.

Sample Compatibility & Compliance

The epMotion 5075l accommodates a broad spectrum of biological and chemical sample types, including genomic DNA, RNA, cell lysates, protein solutions, and small-molecule compound libraries. Its sealed deck design and HEPA-filtered laminar airflow option (available upon request) mitigate aerosol contamination during high-throughput nucleic acid handling. All pipetting operations comply with ISO/IEC 17025 calibration guidelines, and the system supports full validation documentation packages aligned with ASTM E2877 (standard guide for verification of automated liquid handlers) and USP Analytical Instrument Qualification. When configured with 21 CFR Part 11–compliant software, the platform provides electronic signatures, role-based access control, and immutable audit trails required for regulated environments.

Software & Data Management

epBlue software serves as both a programming interface and a data governance engine. Protocols are stored in encrypted XML format with version history, timestamped operator logs, and change tracking. The system supports direct integration with Laboratory Information Management Systems (LIMS) and Electronic Lab Notebooks (ELN) via standardized APIs (RESTful HTTP and OPC UA). Optional barcode scanning enables sample-to-protocol traceability, while scheduled backup routines synchronize method files and run logs to network-attached storage (NAS) or cloud repositories. For quality-critical workflows, epBlue’s “Validation Mode” enforces pre-run checks—including tip presence verification, liquid level confirmation, and deck layout validation—before initiating any pipetting sequence.

Applications

The epMotion 5075l is routinely deployed in molecular biology core facilities for NGS library preparation (tagmentation, adapter ligation, size selection), qPCR setup, CRISPR gRNA screening, and ELISA plate coating. In biopharma QC labs, it executes stability-indicating assays, dissolution testing, and potency assays compliant with ICH Q5C and Q5D. Academic research groups utilize its flexibility for high-content screening (HCS), organoid culture media exchange, and single-cell suspension preparation. Its ability to process 96- and 384-well formats in parallel—combined with programmable pause points and error-recovery logic—makes it especially valuable for multi-day kinetic experiments requiring unattended operation.

FAQ

What regulatory standards does the epMotion 5075l support out of the box?

The base configuration complies with ISO 8655 for pipette calibration and ISO/IEC 17025 for measurement uncertainty reporting. Full 21 CFR Part 11 compliance requires activation of the validated software package and associated administrative controls.
Can the system handle viscous or volatile liquids reliably?

Yes—optical liquid level detection, adjustable aspiration speed profiles, and customizable air-gap volumes allow robust handling of liquids with viscosities up to 100 mPa·s and vapor pressures exceeding 10 kPa at 25 °C.
Is remote monitoring or troubleshooting possible?

Remote desktop access is supported via secure VPN; however, Eppendorf recommends on-site service for hardware diagnostics and preventive maintenance to ensure metrological integrity.
How frequently must the system be calibrated?

Annual calibration is recommended under normal use conditions, though user-performed performance checks (e.g., gravimetric verification per ISO 8655-6) should be conducted daily or per shift in regulated settings.
Does the platform support third-party instrument integration?

Yes—through TTL-triggered I/O ports and Ethernet-based command protocols, the epMotion 5075l can synchronize with plate readers, centrifuges, thermal cyclers, and robotic arms in integrated laboratory automation (ILA) workflows.
