Overview
The Clinkx XinPower 620 Electrophoresis Power Supply is a dual-channel, microprocessor-controlled power source engineered for precise and reproducible electrophoretic separation across agarose, polyacrylamide, and SDS-PAGE applications. It operates on the fundamental principle of applying a controlled electric field across a gel matrix to drive charged biomolecules—such as DNA, RNA, and proteins—through the porous medium at rates determined by their size, charge, and conformation. Unlike single-output units, the XinPower 620 delivers two fully independent output channels, enabling concurrent execution of distinct electrophoretic protocols—e.g., one channel running a high-voltage DNA ladder separation while the other maintains low-current native protein electrophoresis—without cross-interference or manual reconfiguration.
Key Features
- Dual independent output channels (4 terminal pairs total), each programmable with unique voltage, current, power, and timing parameters
- Intuitive 5-inch IPS high-definition touchscreen interface (800 × 480 resolution) with full-view angle support for ergonomic lab operation
- Three selectable output modes: constant voltage (CV), constant current (CC), and constant power (CP), optimized for diverse gel systems and buffer conductivities
- Micro-current hold mode automatically engages upon program completion, delivering ≤10 µA residual current to prevent band diffusion and over-migration during post-run standby
- Comprehensive safety architecture including real-time open-circuit detection, overvoltage cutoff (<310 V threshold), short-circuit and overload current limiting, earth-leakage monitoring (≤0.5 mA trip), and auto-recovery after fault clearance
- One-touch pause/resume functionality allows mid-run interruption and seamless continuation without parameter reset or data loss
- Single-cable terminal connection design minimizes cable clutter and improves workspace organization and electrical noise immunity
Sample Compatibility & Compliance
The XinPower 620 supports standard electrophoresis apparatus from major manufacturers—including C.B.S., Bio-Rad, GE Healthcare, and Thermo Fisher—via universal banana-jack or alligator-clip interfaces. Its stable output characteristics ensure compatibility with high-resistance systems (e.g., low-conductivity TAE/TBE buffers in large-format gels) and low-resistance configurations (e.g., high-salt SDS-PAGE running buffers). The unit complies with IEC 61010-1:2010 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and meets EMC standards per CISPR 11 Class B. While not certified for clinical diagnostics under FDA 21 CFR Part 820, its operational logging and parameter traceability support GLP-aligned laboratory documentation practices.
Software & Data Management
The XinPower 620 operates as a standalone instrument with no proprietary PC software dependency; all protocol configuration, execution, and status monitoring occur locally via the embedded touchscreen OS. Each channel stores up to 20 user-defined methods with timestamped start/stop records. Though it does not feature USB or Ethernet connectivity, the device supports audit-ready manual log generation through on-screen parameter review and timed run history export via optional external thermal printer integration (not included). For laboratories requiring electronic record integrity, the timer-based run logs and micro-current hold activation events satisfy basic ALCOA+ principles for attributable, legible, contemporaneous, original, and accurate data capture in non-GMP research environments.
Applications
- Horizontal and vertical nucleic acid electrophoresis (agarose, pulse-field, and PAGE)
- SDS-PAGE, native PAGE, and 2D electrophoresis for protein characterization
- Western blot transfer (semi-dry and wet systems) with programmable ramping profiles
- Preparative electrophoresis and electroelution protocols requiring precise current regulation
- Teaching laboratories where dual-channel flexibility enables side-by-side comparative experiments (e.g., wild-type vs. mutant DNA fragment analysis)
FAQ
Can the XinPower 620 power two different electrophoresis tanks simultaneously with independent settings?
Yes—each of the two output channels operates autonomously, supporting separate voltage, current, power, and timer configurations.
Does the micro-current hold mode require manual activation?
No—it initiates automatically upon completion of the programmed run time or when the “Pause” command is issued.
Is the unit compatible with high-voltage applications such as isoelectric focusing (IEF)?
No—the maximum output voltage is rated at 300 V, making it unsuitable for IEF or capillary electrophoresis systems requiring >500 V.
What happens during a short-circuit event?
The unit immediately halts output, triggers an audible and visual alarm, displays the fault code, and enters safe standby until the fault is cleared and the “Reset” function is manually confirmed.
Can runtime data be exported digitally?
Not natively—the device retains internal run history but lacks network or mass-storage interfaces; data retrieval is limited to on-screen review or optional thermal printout.
