Overview
The Eppendorf epMotion 5073t is a benchtop, semi-automated liquid handling workstation engineered specifically for high-integrity nucleic acid purification using magnetic bead-based chemistry. It operates on the principle of controlled magnetic separation—where paramagnetic beads bind target nucleic acids in the presence of chaotropic salts and ethanol, followed by precise washing, elution, and collection under programmable magnetic field gradients. Integrated 3D-MagSep technology enables simultaneous mixing, temperature control (4–65 °C), and magnetic capture within a single deck position—eliminating cross-contamination risks associated with multi-position transfer steps. Designed for laboratories performing routine DNA/RNA isolation from blood, saliva, tissue lysates, or cultured cells, the system delivers reproducible yields and purity compliant with downstream applications including qPCR, NGS library preparation, and Sanger sequencing.
Key Features
- Six ANSI/SLAS-compliant deck positions accommodating standard microplates (96-well, deep-well), tubes (1.5–50 mL), and custom carriers
- Touchscreen-enabled compact controller with USB 2.0 port for method export, audit log backup, and firmware updates
- Optical liquid level detection system that identifies sample volume, tip type, and consumable presence—preventing dry aspirates and tip collisions
- Automated tool changer supporting three interchangeable modules: single-channel pipetting head, 8-channel pipetting head, and magnetic separation arm
- Volumetric accuracy across 0.2–1,000 µL range, calibrated per ISO 8655-6 with traceable documentation available upon request
- Integrated 3D-MagSep module combining vortex-like mixing, Peltier-based thermal regulation, and high-gradient magnetic separation in one station—reducing protocol cycle time and positional error
- Optional UV-C germicidal lamp (254 nm) and HEPA-filtered laminar airflow unit for Class II biosafety-level operation in low-containment environments
Sample Compatibility & Compliance
The epMotion 5073t supports a broad spectrum of input matrices—including whole blood (with or without anticoagulants), buccal swabs, FFPE tissue sections, bacterial pellets, and mammalian cell cultures—when used with validated Eppendorf MagMAX™ or similar magnetic bead kits. All protocols adhere to ISO/IEC 17025 requirements for method validation, and instrument logs meet ALCOA+ data integrity criteria (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available). The system supports electronic signature capability when integrated with LIMS or ELN platforms compliant with FDA 21 CFR Part 11 and EU Annex 11.
Software & Data Management
Controlled via epBlue™ software (v3.2+), the workstation provides graphical workflow programming with drag-and-drop step sequencing, real-time status monitoring, and automatic error logging. Each run generates a timestamped audit trail containing operator ID, method version, calibration history, environmental sensor readings (temperature/humidity), and tip usage statistics. Raw log files are stored in encrypted SQLite format and can be exported as CSV or PDF for internal QA review or regulatory submission. Software updates follow a documented change control process aligned with GxP laboratory quality systems.
Applications
- High-yield genomic DNA and total RNA isolation from clinical, environmental, and research specimens
- Preparation of template nucleic acids for quantitative real-time PCR (qRT-PCR) and digital PCR (dPCR)
- Automated setup of NGS library construction workflows—including fragmentation, end-repair, A-tailing, adapter ligation, and size selection
- Serial dilution series generation for standard curve development and assay calibration
- Cell culture maintenance tasks: medium exchange, passaging reagent dispensing, and cytokine stimulation arrays
- Reagent aliquoting, plate normalization, and master mix assembly for high-throughput screening assays
FAQ
Does the epMotion 5073t support third-party magnetic bead kits?
Yes—provided kit protocols are adapted to match the system’s liquid handling parameters, magnetic field strength, and thermal profiles. Eppendorf offers technical support for method porting.
Can the system be integrated into a larger automated lab environment?
It features RS-232 and Ethernet interfaces for bidirectional communication with LIS/LIMS and robotic arms via standardized command sets (e.g., SLAS-ANSI ASC X12).
Is routine maintenance required beyond tip and consumable replacement?
Annual performance verification is recommended, including pipette calibration, magnetic field intensity measurement, and optical sensor alignment—services available through Eppendorf Certified Service Centers.
What safety certifications does the instrument carry?
CE marked per IEC 61010-1:2010, UL 61010-1, and RoHS 2011/65/EU; optional UV/HEPA configuration meets ISO 14644-1 Class 5 cleanroom air specifications.
