Junyi JY600E Electrophoresis Power Supply

Overview

The Junyi JY600E Electrophoresis Power Supply is a microprocessor-controlled, multi-mode DC power source engineered for precision and reliability in nucleic acid and protein electrophoresis applications. It operates on the fundamental principle of applying a controlled electric field across a gel matrix—enabling separation of biomolecules based on charge-to-mass ratio and molecular sieving effects. Designed for compatibility with standard horizontal agarose systems, mini- and midi-format vertical polyacrylamide gels (including SDS-PAGE and native PAGE), acetate membrane electrophoresis, preparative gels, isoelectric focusing (IEF) setups, and electroblotting (Western/Northern transfer), the JY600E delivers stable, low-noise output essential for reproducible band resolution and quantitative analysis. Its dual-core microcontroller architecture ensures real-time feedback regulation, minimizing voltage drift (< ±1% at full load) and current fluctuation under variable load conditions—critical for high-sensitivity detection and downstream applications such as sequencing or mass spectrometry sample preparation.

Key Features

• Triple-mode output control: independently selectable constant voltage (CV), constant current (CC), or constant power (CP) operation—each continuously adjustable across the full output range.
• High-resolution digital control: 1 V, 1 mA, and 1 W resolution enables fine-tuned method optimization for sensitive assays such as low-concentration DNA fragment analysis or high-resolution IEF.
• Advanced programmability: stores up to 100 user-defined electrophoresis protocols; supports stepwise multi-stage runs (up to 10 sequential programs per method) for complex separations requiring gradient voltage/current profiles.
• Real-time operational flexibility: built-in pause function with live parameter adjustment—allowing mid-run modifications without compromising output stability or timing integrity.
• Intelligent safety architecture: integrated protection against overvoltage, overcurrent, overload, open-circuit (no-load), short-circuit, and ground leakage—meeting IEC 61010-1 requirements for laboratory electrical safety.
• Ergonomic interface: backlit LCD displays both setpoints and real-time measured values simultaneously; tactile membrane keys and dedicated shortcut buttons streamline routine workflow in high-throughput labs.

Sample Compatibility & Compliance

The JY600E is validated for use with common electrophoretic systems including Bio-Rad Mini-PROTEAN®, Thermo Fisher Owl E1, Convergent Bioscience HPE-100, and generic horizontal/vertical gel tanks. It supports standard gel formats: 7 × 7 cm to 15 × 15 cm vertical gels, 10 × 10 cm to 20 × 20 cm horizontal gels, and capillary or strip-based IEF carriers. While not certified to GLP/GMP standards out-of-the-box, its programmable memory, audit-ready parameter logging (via optional RS232/USB data export), and deterministic output behavior support compliance with ISO/IEC 17025 method validation requirements and internal SOPs for QC/QA laboratories. The unit conforms to CE marking directives (EMC 2014/30/EU, LVD 2014/35/EU) and RoHS 2011/65/EU material restrictions.

Software & Data Management

The JY600E operates as a standalone instrument with no proprietary software dependency. All methods are configured directly via front-panel interface and retained in non-volatile memory—even after power loss. Optional serial (RS232) or USB-to-serial adapters enable integration with third-party lab information management systems (LIMS) or custom Python/Matlab scripts for automated protocol loading, run logging, and CSV-formatted output export. Timestamped runtime data—including actual V/I/W values, elapsed time, and accumulated V·h—can be retrieved for traceability in regulated environments. Though not FDA 21 CFR Part 11 compliant by default, the device supports manual electronic record practices aligned with ALCOA+ principles when paired with validated data capture workflows.

Applications

• Routine DNA/RNA sizing and purity assessment in agarose gels (e.g., PCR product verification, plasmid prep QC).
• High-resolution protein separation via SDS-PAGE and native PAGE for Coomassie/silver staining or Western blotting.
• Seed variety identification and genetic purity testing using starch or esterase zymogram electrophoresis.
• Electroelution and electrotransfer protocols requiring precise voltage ramping or timed transitions between modes.
• Method development for novel polymer matrices (e.g., PEG-based gels) where dynamic power control prevents thermal denaturation.

FAQ

What gel tank models is the JY600E compatible with?
It interfaces with any standard electrophoresis chamber equipped with 4-mm banana plug inputs—including common mini-gel systems from major OEMs and generic acrylic tanks.
Does the JY600E support gradient voltage programming during a single run?
Yes—via its stepwise mode, users can define up to 10 sequential stages, each with independent voltage/current/power targets and duration, enabling programmed voltage ramping or staged transfer protocols.
Is remote computer control possible?
Yes—using optional RS232 or USB-to-serial adapters, the unit accepts ASCII command sets for parameter setting, start/stop control, and status polling.
How does the auto-shutdown feature function?
The instrument automatically powers down upon completion of the timer or volt-hour target—or if an error condition (e.g., open circuit) persists for >30 seconds.
Can stored methods be exported or backed up externally?
Not natively—but real-time output data and final run logs can be captured externally via serial communication for archival and audit purposes.
