Junyi JY600HC High-Voltage Electrophoresis Power Supply

Overview

The Junyi JY600HC High-Voltage Electrophoresis Power Supply is a microprocessor-controlled DC power source engineered for precision and reliability in nucleic acid and protein electrophoresis applications. It operates on the fundamental principle of controlled electric field-driven migration of charged biomolecules through porous matrices—such as polyacrylamide gels (PAGE), agarose gels, or cellulose acetate membranes—enabling separation based on molecular size, charge, and conformation. Designed to meet the operational demands of academic research laboratories, quality control units in biopharmaceutical manufacturing, and diagnostic testing facilities, the JY600HC delivers stable, programmable output across three independent regulation modes: constant voltage (CV), constant current (CC), and constant power (CP). Its 600 V maximum output supports high-resolution SDS-PAGE, isoelectric focusing (IEF), and preparative electrophoresis protocols requiring elevated field strength, while its 1 mA current resolution ensures fine-grained control for sensitive low-current applications such as native PAGE or capillary electrophoresis pre-screening.

Key Features

• Triple-mode output regulation (CV/CC/CP) with real-time dual-display of setpoint and actual values
• High-resolution digital control: ±1 V voltage accuracy, ±1 mA current accuracy, ±1 W power accuracy
• Extended timing capability from 1 minute to 99 hours 59 minutes, supporting overnight and multi-stage runs
• Non-volatile memory storing up to 10 frequently used electrophoresis methods with full parameter recall
• Intelligent safety architecture including automatic shutdown on overload, open-circuit (no-load), and ground-fault detection
• Tactile membrane keypad with ergonomic layout and backlight-enabled LCD for low-light lab environments
• Four isolated output port pairs enabling concurrent operation of multiple gel units or hybrid configurations (e.g., horizontal + vertical)
• Optional power-fail resume function preserves method integrity during unexpected utility interruptions
• Field uniformity enhancement mode minimizes edge effects and band distortion in wide-format gels via optimized electrode geometry compensation

Sample Compatibility & Compliance

The JY600HC is compatible with standard electrophoresis apparatus from major global manufacturers—including but not limited to Bio-Rad, C.B.S. Scientific, and Owl Separation Systems—when configured with appropriate buffer chambers and electrode assemblies. It supports common gel formats: mini- and midi-vertical SDS-PAGE (up to 20 cm height), horizontal agarose systems (up to 25 × 25 cm), cellulose acetate membrane electrophoresis, and preparative slab gels. While the unit itself is not CE-marked or FDA-listed as a medical device, its electrical safety design conforms to IEC 61010-1:2010 requirements for laboratory equipment. When integrated into validated workflows under Good Laboratory Practice (GLP) or cGMP environments, the instrument’s programmable memory, timestamped run logging (via external data capture), and deterministic output behavior support audit readiness per 21 CFR Part 11 when paired with compliant software interfaces.

Software & Data Management

The JY600HC operates as a standalone hardware controller without embedded networking or proprietary software dependencies. All method parameters—including voltage, current, power, duration, and mode selection—are configured directly via front-panel interface and retained in non-volatile memory. For traceable documentation, users may manually record run metadata (date/time, method ID, gel type, sample load) in electronic lab notebooks (ELNs) or LIMS platforms. The device outputs no raw analog or digital data streams; however, its consistent output stability and repeatability (<0.5% variation across repeated identical settings) enable robust inter-laboratory protocol transfer. Optional RS-232 or USB-to-serial adapters (sold separately) allow integration with third-party automation scripts for scheduled batch runs in high-throughput screening labs.

Applications

• Denaturing and native protein separation via SDS-PAGE and BN-PAGE
• Nucleic acid analysis in agarose and polyacrylamide gels (e.g., PCR product verification, restriction digest profiling)
• Isoelectric focusing (IEF) for pI-based protein characterization
• Cellulose acetate electrophoresis for serum protein fractionation in clinical diagnostics
• Electroblotting (Western, Southern, Northern transfers) requiring precise voltage ramping
• Seed purity testing and varietal identification using starch gel electrophoresis
• Preparative electrophoresis for downstream protein purification and recovery

FAQ

Does the JY600HC support gradient voltage or time-programmed multi-step runs?
No—the JY600HC executes single-parameter, fixed-setpoint runs only. Multi-step protocols require manual intervention or external timer-based switching.
Is remote control or computer interface included?
No built-in connectivity is provided; optional serial adapters may be used for basic command-line triggering, but no official driver or SDK is supplied.
Can it be used with miniaturized microfluidic electrophoresis chips?
Yes—within its 1–1000 mA current range and low-noise output design, it is suitable for chip-based assays requiring stable low-current delivery, provided appropriate voltage-limiting resistors are integrated into the chip holder.
What maintenance is required for long-term calibration stability?
No routine recalibration is specified by the manufacturer; periodic verification using a certified multimeter (NIST-traceable) is recommended annually for GLP-compliant operations.
Is the unit compliant with ISO/IEC 17025 for accredited testing laboratories?
As a power supply—not a measurement instrument—it falls outside scope of ISO/IEC 17025 accreditation; however, its documented output consistency supports method validation within accredited workflows.
