Junyi JY600C Electrophoresis Power Supply

Overview

The Junyi JY600C Electrophoresis Power Supply is a microprocessor-controlled, laboratory-grade DC power source engineered for precise and reproducible electrophoretic separation of biomolecules—including proteins, nucleic acids, and peptides—across a wide range of gel-based analytical formats. It operates on the fundamental principle of electrophoresis: applying a controlled electric field across a conductive medium (e.g., polyacrylamide or agarose gels) to drive charged macromolecules at rates proportional to their charge-to-mass ratio and conformational resistance. Designed specifically for protein electrophoresis applications—including SDS-PAGE, native PAGE, isoelectric focusing (IEF), and electroblotting—the JY600C delivers stable, low-ripple DC output with real-time monitoring of voltage, current, and power parameters. Its triple-mode operation (constant voltage, constant current, or constant power) enables method flexibility across diverse experimental configurations—from high-resolution mini-gel systems to multi-gel vertical or horizontal setups—without manual recalibration or hardware reconfiguration.

Key Features

• Triple-output control modes: Selectable constant voltage (10–600 V), constant current (1–500 mA), or constant power (1–300 W), each continuously adjustable in 1-unit increments for fine-grained protocol optimization.
• High-resolution digital display: Backlit 128 × 64 pixel LCD simultaneously shows both setpoint and real-time output values—eliminating guesswork during method execution.
• Intelligent memory architecture: Stores up to 10 complete electrophoresis protocols—including voltage/current/power setpoints, timer duration, and mode selection—for rapid recall and repeatable runs.
• Comprehensive safety system: Integrated protection against overload, open-circuit (no-load), and ground-fault leakage ensures operator safety and equipment longevity per IEC 61010-1 compliance requirements.
• Durable industrial design: One-piece molded housing with tactile membrane keypad provides chemical resistance, mechanical stability, and ergonomic accessibility in shared lab environments.
• Extended timing capability: Programmable timer supports durations from 1 minute to 99 hours and 59 minutes—enabling overnight or multi-day electrophoresis without manual intervention.

Sample Compatibility & Compliance

The JY600C is compatible with standard electrophoresis apparatuses used in academic, clinical, and quality control laboratories—including vertical slab gel units (e.g., Mini-PROTEAN, SE600), horizontal submarine gels, capillary electrophoresis interfaces (with appropriate adapters), and blotting transfer modules. It supports common buffer systems such as Tris-Glycine, Tris-Acetate, and Bis-Tris MOPS, and maintains stable output under variable load conditions typical of gradient gels or high-conductivity running buffers. While not certified to ISO/IEC 17025 or FDA 21 CFR Part 11 out-of-the-box, its programmable memory, audit-ready parameter logging (via optional RS232/USB interface), and deterministic shutdown behavior support GLP/GMP-aligned documentation workflows when integrated into validated laboratory information management systems (LIMS).

Software & Data Management

The JY600C operates as a standalone instrument with embedded firmware—no host PC required for routine operation. All settings are retained after power cycling due to non-volatile memory. For traceable data capture, optional serial (RS232) or USB connectivity enables integration with third-party acquisition software (e.g., LabVIEW, Python-based automation scripts) to log timestamped output parameters and trigger external events (e.g., camera capture upon run completion). The unit’s auto-memory and auto-shutdown functions facilitate unattended operation while maintaining regulatory alignment with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) when paired with appropriate electronic record practices.

Applications

• SDS-PAGE and native PAGE for protein molecular weight estimation and purity assessment
• Two-dimensional electrophoresis (2-DE) first-dimension IEF using immobilized pH gradient (IPG) strips
• Horizontal electrophoresis of DNA fragments, RNA integrity checks, and plasmid analysis
• Electrotransfer (Western, Southern, Northern blotting) onto PVDF or nitrocellulose membranes
• Seed purity testing and cultivar identification via starch or esterase zymogram electrophoresis
• Preparative electrophoresis for downstream protein purification and functional characterization

FAQ

What electrophoresis tank models are compatible with the JY600C?
The JY600C features four independent output ports rated for standard 2-mm banana plug connections and is compatible with any commercially available electrophoresis chamber operating within its 600 V / 500 mA / 300 W limits—including Bio-Rad, C.B.S. Scientific, and Hoefer units.
Does the JY600C support remote control or computer interfacing?
Yes—optional RS232 or USB communication modules enable bidirectional command/control and real-time parameter streaming for automated lab environments.
Can the JY600C be used for isoelectric focusing (IEF)?
Yes—its constant voltage mode with fine 1-V resolution and low output ripple (<0.5% RMS) provides the stable field required for reproducible IPG strip focusing.
Is the unit suitable for regulated QC/QA labs under GMP or CLIA guidelines?
While the base unit lacks built-in 21 CFR Part 11 compliance features, its deterministic behavior, parameter memory, and optional data logging support validation when deployed within documented SOPs and supporting infrastructure.
What safety certifications does the JY600C carry?
It conforms to IEC 61010-1:2010 for electrical safety in laboratory equipment; CE marking applies for European Economic Area distribution.
