Overview
The Eppendorf epMotion 5073l is a benchtop liquid handling workstation engineered for high-precision, low-volume pipetting in molecular biology and diagnostic workflows—particularly nucleic acid extraction, PCR setup, and assay plate preparation. Based on positive-displacement and air-displacement pipetting principles with integrated optical liquid level detection, the system delivers traceable, reproducible liquid transfers across microtiter plates, tubes, and reservoirs. Its modular architecture supports both routine automation of standardized protocols and flexible method development for non-standard sample formats. Designed and manufactured in Hamburg, Germany, the epMotion 5073l complies with IEC 61000-6-2 (EMC immunity) and IEC 61000-6-4 (EMC emissions), and meets CE marking requirements for laboratory instrumentation under the EU Machinery Directive 2006/42/EC.
Key Features
- Six ANSI/SLAS-compliant deck positions accommodating standard microplates (96-well, 384-well), tube racks (0.2–50 mL), and custom labware—enabling multi-step workflows without manual intervention.
- Optical sensor system for real-time detection of liquid surface, tip attachment, consumable presence, and deck obstruction—ensuring error-free operation and minimizing reagent waste.
- Automatic tool changer supporting simultaneous integration of two independent pipetting tools: single-channel and 8-channel configurations, each calibrated per ISO 8655-6 for volumetric accuracy.
- True sub-microliter precision: certified accuracy of ±0.05 µL at 1 µL, validated per ISO 8655-2 and traceable to national metrology institutes (e.g., PTB).
- Enclosed safety hood with interlocked sliding door and optional UV-C germicidal lamp (254 nm) plus HEPA-filtered laminar airflow—meeting ISO 14644-1 Class 5 cleanroom specifications for contamination-sensitive applications.
- Intuitive epBlue software with guided protocol builder, drag-and-drop workflow editor, and embedded validation templates compliant with GLP and GMP documentation requirements.
Sample Compatibility & Compliance
The epMotion 5073l handles diverse primary sample containers including PCR tubes (0.2 mL), skirted and semi-skirted 96-well plates, deep-well plates (1.2–2.2 mL capacity), and conical centrifuge tubes (15–50 mL). It supports all major nucleic acid extraction kits (e.g., QIAamp, MagMAX, NucleoSpin) via customizable deck layouts and tip types (low-retention, filtered, or sterile). All hardware and software components are designed to support audit-ready compliance: electronic records and signatures meet FDA 21 CFR Part 11 requirements when configured with MultiCon PC and optional audit trail module; calibration logs, user access controls, and version-controlled protocol archives align with ISO/IEC 17025 and CLIA standards.
Software & Data Management
epBlue software provides a unified interface for method creation, execution, and data export. Protocols are stored as XML-based files with embedded metadata (user ID, timestamp, instrument serial number, calibration status). The system supports direct export to LIMS via CSV, Excel, or HL7-compatible formats. Optional modules include barcode scanning (for tube/plate tracking), electronic signature capture, and full audit trail logging—including who changed what, when, and why—with immutable timestamps. Software validation packages (IQ/OQ/PQ documentation) are available upon request for regulated environments.
Applications
- Automated nucleic acid isolation from blood, saliva, tissue homogenates, and environmental swabs using magnetic bead or column-based chemistries.
- High-fidelity PCR and qPCR master mix assembly—including dual-indexed library prep for NGS—with volume consistency critical for amplification efficiency and Ct value reproducibility.
- Serial dilution series generation (e.g., standard curves, IC50 determination) with coefficient of variation (CV) < 1.5% at 5 µL across 96 replicates.
- Cell culture maintenance: medium exchange, passaging, and reagent addition with temperature-controlled deck options (4–40 °C).
- Compound screening plate replication, ELISA plate coating, and antibody titration—all requiring strict inter-run precision and cross-contamination control.
FAQ
Is the epMotion 5073l compatible with third-party consumables?
Yes—it accepts ANSI/SLAS-standard tips, plates, and tubes from major suppliers (e.g., Corning, Sarstedt, Greiner Bio-One), provided dimensional tolerances fall within Eppendorf’s published specifications.
Can it be integrated into a larger automated lab ecosystem?
Yes—via RS-232, Ethernet, or USB interfaces, the system supports bidirectional communication with LIMS, robotic arms, and incubators using Modbus TCP or custom API scripting.
What maintenance is required to sustain accuracy over time?
Daily tip ejection verification, weekly optical sensor cleaning, and annual factory recalibration (recommended per ISO/IEC 17025) ensure long-term performance stability.
Does it support temperature-controlled pipetting?
The base model operates at ambient temperature; however, Peltier-cooled or heated deck modules (–10 to 60 °C) are available as field-upgradable accessories.
How is user access managed in shared-lab environments?
Multi-level authentication (password + optional LDAP/Active Directory integration), role-based permissions (operator, technician, administrator), and session timeout policies enforce accountability and data integrity.
