Analytik Jena Eco-Mini and Eco-Maxi Vertical Electrophoresis Systems

Overview

The Analytik Jena Eco-Mini and Eco-Maxi Vertical Electrophoresis Systems are compact, modular, and CE-certified electrophoretic platforms engineered for high-reproducibility SDS-PAGE, native PAGE, and Western blot transfer applications in academic, clinical, and industrial life science laboratories. Designed around the fundamental principles of constant-voltage or constant-current electrophoresis in polyacrylamide gels, these systems implement a robust vertical slab-gel architecture that supports both electrophoretic separation and subsequent wet-transfer electroblotting—without hardware reconfiguration. The dual-gel capability enables parallel processing of up to two 8 × 7 cm gels per run, significantly improving throughput while maintaining consistent field homogeneity across the gel matrix. All components—including electrode assemblies, buffer chambers, and gel positioning slots—are precision-machined to ensure dimensional repeatability and minimize edge effects during migration.

Key Features

• Integrated electrophoresis and wet-transfer functionality—no tool-based conversion required; switch between modes via simple repositioning of the gel cassette and electrode orientation.
• 3-mm-thick borosilicate glass plates with permanently affixed sealing spacers ensure precise inter-plate alignment, eliminate gel leakage, and prevent spacer loss during assembly.
• Dedicated gel-retention slots accommodate either triple-layer glass cassettes (for casting) or pre-assembled transfer夹 plates, enabling secure, vibration-resistant positioning during high-voltage runs.
• Ergonomic safety lid with reinforced lateral flanges remains vertically stable when open—reducing bench clutter and preventing contamination from lid contact with work surfaces.
• Combs calibrated to standard 8-channel pipette spacing allow rapid, reproducible loading of multi-sample arrays without manual alignment adjustments.
• Optional integrated recirculating cooling unit maintains buffer temperature within ±0.5 °C across the entire chamber, mitigating Joule heating-induced band distortion and smearing—critical for high-resolution protein separation.
• Seal-free casting system: proprietary silicone gasket design eliminates need for clamps or rubber bands; ensures leak-proof polymerization even at low acrylamide concentrations (e.g., 3–4% stacking gels).

Sample Compatibility & Compliance

The Eco-Mini and Eco-Maxi support both hand-cast and commercially available precast polyacrylamide gels (including gradient and Tris-Tricine formulations), accommodating molecular weight ranges from 250 kDa. Compatible with standard Laemmli, Bis-Tris, and MOPS-based running buffers. Systems comply with IEC 61010-1:2012 for laboratory electrical safety and meet EN 61326-1:2013 electromagnetic compatibility requirements. All plastic components are autoclavable (121 °C, 20 min) and resistant to common electrophoresis solvents (e.g., ethanol, isopropanol, SDS solutions). Documentation packages include EU Declaration of Conformity and traceable calibration records for voltage/current output verification—supporting GLP/GMP-aligned lab audits.

Software & Data Management

While the Eco-Mini and Eco-Maxi operate as standalone analog instruments, they are fully compatible with third-party digital documentation workflows. Voltage and current outputs are monitored via front-panel analog meters with ±2% full-scale accuracy (NIST-traceable calibration optional). For regulatory environments requiring electronic records, integration with LabVantage, LabWare LIMS, or custom Python-based acquisition scripts (via RS-232 or USB-to-serial adapters) enables time-stamped parameter logging, run archiving, and audit trail generation compliant with FDA 21 CFR Part 11 Annex 11 requirements. Optional firmware upgrade kits support programmable ramping profiles and endpoint-triggered shutdown—enhancing reproducibility in routine QC testing.

Applications

• Routine SDS-PAGE analysis of recombinant proteins, cell lysates, and purified antibodies.
• Native PAGE for oligomeric state assessment and enzyme activity profiling under non-denaturing conditions.
• High-fidelity wet-transfer electrophoresis for downstream immunodetection (Western blotting) with optimized transfer efficiency across broad MW ranges.
• Teaching laboratory use: intuitive mechanical design and fail-safe voltage limits (max 300 V) make it suitable for undergraduate biochemistry and molecular biology instruction.
• QC release testing in biomanufacturing: validated performance across ≥500 consecutive runs supports qualification under ISO 13485 and ICH Q5E guidelines.

FAQ

Can the Eco-Mini/Eco-Maxi be used with precast gels from other manufacturers?

Yes—the 8 × 7 cm format aligns with industry-standard mini-gel dimensions; compatibility has been verified with Bio-Rad, Thermo Fisher, and Lonza precast gels.
Is the cooling unit mandatory for optimal performance?

Not mandatory, but strongly recommended for runs exceeding 120 min or at voltages >200 V; uncooled operation may result in thermal gradients affecting band sharpness.
What maintenance is required for long-term reliability?

Annual inspection of electrode corrosion status, periodic replacement of silicone gaskets (every 2 years under daily use), and cleaning of buffer chamber ports with 70% ethanol.
Does the system support constant-power mode?

No—it operates exclusively in constant-voltage or constant-current mode, consistent with ISO 10993-12 and ASTM D2765 electrophoresis method standards.
Are spare parts and service manuals available internationally?

Yes—Analytik Jena’s global service network provides certified spare glass plates, combs, gaskets, and technical bulletins in English, German, French, and Japanese.
