Overview
The DLAB DEP-600 Electrophoresis Power Supply is a precision-engineered benchtop power source designed for consistent, programmable, and safe operation of horizontal and vertical electrophoresis systems—including SDS-PAGE, native PAGE, agarose gel electrophoresis, and pulse-field applications. It operates on constant-voltage, constant-current, or constant-power modes—automatically switching between them based on real-time load conditions—to maintain experimental integrity across diverse gel matrices and buffer conductivities. Its microprocessor-controlled architecture ensures stable output under varying thermal and electrical loads, minimizing run-to-run variability and supporting reproducible separation profiles required in molecular biology, clinical diagnostics, and academic research laboratories.
Key Features
- High-resolution 4.3-inch LCD touchscreen interface with intuitive menu navigation for rapid parameter setup, real-time monitoring, and progress visualization.
- Full-range adjustable output: 0–600 V DC, 0–500 mA, 0–300 W—with digital feedback control ensuring ±1% accuracy across all operating modes.
- Multi-step programmable protocol support: up to 10 user-defined programs stored internally; each program accommodates up to 10 time-segmented steps with independent voltage/current/power targets.
- Dual-CPU redundancy architecture enhances system stability, reduces drift during extended runs (>24 h), and enables seamless response to dynamic impedance changes during electrophoretic migration.
- Intelligent power recovery: upon unexpected power interruption, the unit resumes operation from the last saved step—including elapsed time and output settings—subject to user-configurable restart policy.
- Low-current maintenance mode: programmable standby current (1–30 mA) sustains gel integrity during pre-run equilibration or post-run cooling without compromising resolution.
- Comprehensive safety suite: short-circuit protection, open-circuit (no-load) detection, over-temperature shutdown, and configurable audible alarm (on/off, tone duration, trigger threshold).
- Ergonomic design: recessed anti-slip grooves enable secure vertical stacking of multiple units; pop-up adjustable-angle stand improves operator visibility and reduces neck strain during prolonged use.
- Quad-output configuration: four independent high-isolation DC output channels (labeled A–D), each with dedicated binding posts and LED status indicators—enabling simultaneous operation of up to four electrophoresis tanks with independent parameter control.
Sample Compatibility & Compliance
The DEP-600 is compatible with standard electrophoresis chambers from major vendors (e.g., Bio-Rad, Thermo Fisher, GE Healthcare, and local OEMs), supporting slab gels (up to 20 × 20 cm), mini-gels, capillary arrays, and blotting modules. Output isolation meets IEC 61010-1:2010 requirements for laboratory electrical equipment, including creepage/clearance distances and reinforced insulation between output channels and chassis ground. The unit complies with electromagnetic compatibility (EMC) standards per EN 61326-1:2013 and carries CE marking for use within the European Economic Area. While not certified for IVD or GMP production environments, its audit-ready parameter logging (via USB flash drive) supports GLP-aligned documentation practices in academic and contract research settings.
Software & Data Management
No proprietary desktop software is required for basic operation; however, the DEP-600 supports export of runtime logs—including timestamped voltage, current, power, and temperature data—in CSV format via standard USB 2.0 interface. Logs are generated at 1-second intervals and retain full metadata (program ID, user tag, start/stop time). These files are directly importable into Excel, GraphPad Prism, or LabArchives for traceability, statistical analysis, and report generation. All parameter changes—including manual overrides—are timestamped and recorded in non-volatile memory, satisfying minimum ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate) for method validation documentation.
Applications
- Denaturing and non-denaturing protein electrophoresis (SDS-PAGE, BN-PAGE, Zymography)
- Nucleic acid separation (agarose and polyacrylamide gels for DNA/RNA sizing, RFLP, PCR product analysis)
- Western blot transfer optimization (semi-dry and wet transfer protocols)
- Electroelution and electroblotting workflows requiring precise low-current control
- Teaching laboratories requiring robust, multi-user programmability and fail-safe operation
FAQ
Does the DEP-600 support remote control via RS-232 or Ethernet?
No—this model features standalone operation only. Remote command capability is not implemented; all configuration and monitoring occur via the front-panel touchscreen.
Can I export logs while the instrument is running?
Yes—USB data logging is active in real time; insertion of a formatted FAT32 USB drive initiates automatic file writing without interrupting the electrophoresis run.
Is the output galvanically isolated between channels?
Yes—each of the four output pairs (A–D) is independently isolated with ≥1 kV DC withstand rating, preventing cross-talk when powering dissimilar gel systems simultaneously.
What is the maximum continuous duty cycle at rated power?
The unit is rated for continuous operation at ≤250 W ambient temperature ≤30 °C; derating to 80% capacity is recommended above 35 °C to ensure long-term reliability.
Are replacement fuses user-serviceable?
Yes—front-accessible fuse holders contain slow-blow ceramic fuses (T3.15A L 250 V); spare fuses are included with initial shipment and specified in the technical manual.
