Junyi JY600 Electrophoresis Power Supply

Overview

The Junyi JY600 Electrophoresis Power Supply is a microprocessor-controlled DC power source engineered for precision and reliability in routine protein and nucleic acid electrophoresis applications. It operates on the fundamental principle of applying a controlled electric field across a gel matrix—typically polyacrylamide (PAGE), SDS-PAGE, or agarose—to drive charged biomolecules toward oppositely charged electrodes at rates proportional to their size-to-charge ratio. Designed for compatibility with standard horizontal and中小型 vertical electrophoresis systems—including mini-gel units and cellulose acetate membrane setups—the JY600 delivers stable, low-noise DC output essential for reproducible band resolution and minimal thermal distortion during extended runs. Its dual-mode architecture supports both constant voltage and constant current operation, enabling users to select the optimal excitation profile based on gel composition, buffer conductivity, and experimental duration.

Key Features

• Intelligent dual-mode output: Selectable constant voltage (CV) or constant current (CC) operation with automatic dynamic adjustment—e.g., when CV mode is engaged, the unit maximizes current within safe limits; in CC mode, it adjusts voltage to maintain target current.
• High-resolution digital control: 1 V voltage resolution and 1 mA current resolution ensure fine-grained parameter tuning for method optimization and inter-laboratory protocol alignment.
• Dual LED display: Simultaneously monitors real-time voltage and current values, eliminating ambiguity during method setup and troubleshooting.
• Programmable timer: Adjustable from 1 minute to 9 hours and 59 minutes, supporting both short diagnostic runs and overnight separations without manual intervention.
• Robust safety architecture: Integrated protections include overload shutdown, open-circuit detection (preventing damage during unconnected electrode scenarios), and leakage current monitoring compliant with IEC 61010-1 Class II insulation requirements.
• Ergonomic industrial design: One-piece molded housing with tactile membrane keys ensures durability, ease of cleaning, and resistance to common laboratory solvents and buffer splashes.
• Auto-memory and auto-shutdown: Retains last-used settings across power cycles and initiates graceful shutdown upon timer expiration or fault condition detection.

Sample Compatibility & Compliance

The JY600 is validated for use with standard electrophoretic formats including slab gels (up to mini-vertical configurations), horizontal agarose gels (1–3% w/v), and cellulose acetate membranes—commonly employed in clinical serum protein electrophoresis (SPE). While not intended for high-throughput or ultra-high-voltage applications (e.g., capillary or pulsed-field electrophoresis), its 600 V ceiling meets ASTM D4294 and ISO 10566 guidelines for conventional gel-based separation systems. The unit complies with GB/T 14710–2009 (Chinese Environmental Adaptability Standard for Medical Electrical Equipment) and conforms to general electrical safety expectations for Class I laboratory equipment under IEC 61010-1. It does not incorporate FDA 21 CFR Part 11-compliant audit trails or electronic signature functionality, positioning it for research and teaching environments rather than regulated GMP/GLP production labs.

Software & Data Management

The JY600 operates as a standalone hardware platform with no embedded software, network interface, or PC connectivity. All configuration and monitoring occur via front-panel controls and dual LED readouts. This design eliminates driver dependencies, firmware update cycles, and cybersecurity surface area—making it suitable for resource-constrained labs, educational institutions, and cleanroom-adjacent workflows where device simplicity and operational continuity are prioritized. Parameter logging requires manual recording; integration with external data acquisition systems (e.g., via analog voltage/current output signals) is not supported natively but may be achieved using third-party signal conditioning modules.

Applications

• SDS-PAGE and native PAGE for protein molecular weight estimation and purity assessment.
• Agarose gel electrophoresis of PCR products, plasmid DNA, and restriction digests.
• Clinical serum protein electrophoresis (SPE) on cellulose acetate or agarose supports for albumin/globulin fraction analysis.
• Western blot transfer optimization (semi-dry or tank transfer) requiring stable low-current conditions.
• Undergraduate and graduate teaching laboratories where robustness, intuitive operation, and cost-effectiveness are critical selection criteria.

FAQ

What gel systems is the JY600 compatible with?
It supports standard horizontal agarose gels, mini-vertical SDS-PAGE systems (e.g., Bio-Rad Mini-PROTEAN–compatible tanks), and cellulose acetate membrane electrophoresis units.
Does the JY600 support programmable ramping or gradient voltage profiles?
No—it provides only steady-state constant voltage or constant current output; multi-step or time-varying protocols require external controller integration.
Is the unit suitable for high-voltage applications such as isoelectric focusing (IEF)?
Not recommended: While rated up to 600 V, the JY600 lacks the precision temperature compensation and voltage stability required for IEF or 2D electrophoresis.
Can output parameters be recalled after power loss?
Yes—the microprocessor retains the last active voltage/current/timer settings in non-volatile memory and restores them on reboot.
What safety certifications does the JY600 hold?
It meets GB/T 14710–2009 environmental adaptability standards and adheres to IEC 61010-1 general safety requirements for laboratory electrical equipment; CE marking is not present.
