Junyi JY1600E Electrophoresis Power Supply

Overview

The Junyi JY1600E Electrophoresis Power Supply is a high-voltage, microprocessor-controlled laboratory instrument engineered for precision and reliability in nucleic acid and protein separation workflows. Designed around the fundamental principle of electrophoretic mobility—where charged biomolecules migrate through a gel matrix under an applied electric field—the JY1600E delivers stable, programmable power across three independent operating modes: constant voltage (CV), constant current (CC), and constant power (CP). Its 1600 V maximum output supports demanding applications including preparative polyacrylamide gel electrophoresis (PAGE), SDS-PAGE, isoelectric focusing (IEF), and denaturing gradient gel electrophoresis (DGGE), while its wide current range (1–200 mA) accommodates both low-current native gels and high-current denaturing systems. The unit’s dual-core control architecture ensures real-time feedback regulation, minimizing output drift during extended runs—critical for reproducible band resolution and inter-laboratory comparability.

Key Features

• Triple-mode output control (CV/CC/CP) with continuous adjustment and simultaneous display of setpoint and real-time values
• High-resolution digital control: 1 V, 1 mA, and 1 W resolution across full output ranges
• Intuitive touch-sensitive interface with dedicated shortcut keys for rapid protocol access and parameter entry
• Comprehensive method management: 100 programmable electrophoresis protocols stored in non-volatile memory
• Advanced stepwise operation: Up to 10 multi-step sequences, each containing up to 10 individually timed and mode-switched segments
• Pause-and-adjust functionality with zero-output-interruption; real-time fine-tuning preserves voltage/current stability during interruption
• Integrated safety suite: Automatic detection and shutdown for open-circuit, overload, leakage current, and thermal over-limit conditions
• Backlit LCD with clear segment-based readout of voltage, current, power, elapsed time, and accumulated volt-hours (V·h)

Sample Compatibility & Compliance

The JY1600E is compatible with standard vertical and horizontal electrophoresis chambers used in academic, clinical, and industrial life science laboratories—including mini- and midi-sized SDS-PAGE units, IEF rods, SSCP gels, and cellulose acetate membrane systems. It meets general electrical safety requirements per IEC 61010-1 for laboratory equipment and incorporates design features aligned with Good Laboratory Practice (GLP) documentation needs: auto-memory of last-used parameters, timestamped method recall, and unambiguous output logging via front-panel display. While not certified to FDA 21 CFR Part 11, its deterministic control logic, absence of ambiguous states, and repeatable method execution support audit-ready workflows in regulated environments where traceability of electrophoretic conditions is essential.

Software & Data Management

The JY1600E operates as a standalone, embedded-system device with no external software dependency. All operational data—including preset parameters, real-time outputs, timer status, and accumulated volt-hours—are retained on the integrated LCD and preserved across power cycles via non-volatile memory. Method storage supports full parameter replication: users may define voltage, current, power, duration, and step transitions without external configuration files. For laboratories requiring integration into broader LIMS or ELN ecosystems, manual transcription of displayed parameters (e.g., “Step 1: 150 V, 30 min; Step 2: 200 V, 60 min”) satisfies basic electronic record requirements under ISO/IEC 17025 Clause 7.5. No proprietary drivers, USB connectivity, or cloud synchronization are implemented—ensuring electromagnetic compatibility and eliminating firmware update dependencies.

Applications

The JY1600E serves core electrophoretic techniques across molecular biology, proteomics, and diagnostics. It enables high-resolution separation of DNA fragments in agarose and polyacrylamide matrices, quantitative protein profiling via SDS-PAGE, and high-fidelity isoelectric point determination in IEF. Its programmable step function supports complex protocols such as two-dimensional electrophoresis (2-DE) first-dimension focusing followed by second-dimension SDS migration. In clinical labs, it supports SSCP analysis for mutation screening and cellulose acetate electrophoresis for serum protein fractionation. Its 320 W maximum power output ensures consistent field strength even in large-format or high-conductivity buffer systems—reducing run-to-run variability in quantitative densitometry and downstream Western blotting.

FAQ

What electrophoresis chamber types are compatible with the JY1600E?
The JY1600E supports all standard vertical and horizontal electrophoresis tanks rated for ≤1600 V input, including mini-gel, midi-gel, and preparative systems from major OEMs.
Does the unit support GLP-compliant data recording?
It provides on-device display and memory of all critical run parameters; however, manual documentation or external video capture is required for formal GLP audit trails.
Can multiple output ports be used simultaneously?
Yes—four independent output pairs allow concurrent operation of up to four electrophoresis units, provided total load remains within 320 W and 200 mA limits.
Is firmware upgrade capability available?
No—the device uses hardened embedded firmware with no user-accessible update mechanism, ensuring long-term operational consistency.
What safety certifications does the JY1600E hold?
It complies with IEC 61010-1 for electrical safety in laboratory equipment; CE marking is not applicable as it is manufactured for domestic Chinese market distribution.
