DLAB DL-SUB02 Multi-Format Horizontal Electrophoresis System

Overview

The DLAB DL-SUB02 Multi-Format Horizontal Electrophoresis System is an engineered platform for nucleic acid and protein separation under standardized agarose or polyacrylamide gel electrophoresis (AGE/PAGE) conditions. Designed in accordance with fundamental electrokinetic principles—where charged biomolecules migrate through a porous matrix under a uniform DC electric field—the DL-SUB02 supports reproducible, high-resolution band resolution across variable molecular weight ranges. Its modular tray architecture accommodates four distinct gel formats within a single chassis, enabling laboratories to optimize throughput, resolution, and reagent economy without hardware substitution. The system operates at standard voltage ranges (typically 50–150 V DC) and is compatible with common electrophoretic buffers including TAE, TBE, and SB. All structural components are fabricated from medical-grade, UV-transparent thermoplastic polymers certified for repeated autoclaving (121 °C, 20 min), ensuring long-term dimensional stability and chemical resistance to ethidium bromide, SYBR Safe, and other intercalating dyes.

Key Features

• Four interchangeable gel formats—Large (120 × 120 mm), Wide (120 × 60 mm), Long (60 × 120 mm), and Small (60 × 60 mm)—configured via a single, tool-free tray assembly system
• Integrated fluorescent calibration scale embedded into the base tray surface, visible under standard 302 nm UV transillumination, facilitating precise well positioning and migration distance measurement
• Patented lid-actuated safety circuit that automatically interrupts power supply upon lid removal—compliant with IEC 61010-1:2010 Class II laboratory equipment safety requirements
• Removable platinum-coated stainless steel electrodes (99.99% Pt purity) mounted on corrosion-resistant PEEK carriers, enabling full access for cleaning, inspection, and replacement without disassembly of the main chamber
• Top-mounted ventilation array with directional airflow channels, reducing localized buffer temperature rise by ≥35% compared to sealed-lid systems during extended runs (>90 min)
• Injection-molded housing rated for continuous operation at ambient temperatures up to 40 °C and short-term exposure to buffer temperatures up to 80 °C

Sample Compatibility & Compliance

The DL-SUB02 supports standard agarose concentrations (0.7–3.0%) and native/denaturing polyacrylamide gels (4–20% gradient). Its 700 mL buffer reservoir maintains stable conductivity and thermal homogeneity across all gel formats, minimizing edge effects and band distortion. Sample loading is facilitated by eight comb configurations (2-, 3-, 6-, 8-, 11-, 13-, 18-, and 25-well), each precision-machined to ensure uniform well depth (1.5 mm) and spacing tolerance ≤ ±0.1 mm. The system meets ISO 13485 design control documentation standards for in vitro diagnostic support instrumentation and is routinely validated in GLP-compliant QC labs for routine DNA fragment analysis per ISO/IEC 17025:2017 Annex A.2 requirements.

Software & Data Management

While the DL-SUB02 is a standalone electrophoresis cell requiring no proprietary controller, it is fully interoperable with third-party imaging and analysis platforms—including Bio-Rad GelDoc™, Azure Sapphire™, and UVP ChemStudio™—via standardized gel dimensions and UV-compatible tray geometry. All physical markings (fluorescent scale, electrode alignment notches, buffer level indicators) are calibrated to NIST-traceable dimensional references. For audit readiness, users may log run parameters (voltage, duration, buffer lot number, gel concentration) manually or integrate with LIMS via CSV export from companion documentation templates aligned with FDA 21 CFR Part 11 electronic record guidelines.

Applications

• Routine PCR product verification and restriction digest analysis in molecular biology core facilities
• Quality control of plasmid preps, CRISPR editing validation, and cDNA library screening
• Teaching laboratory implementation of foundational electrophoretic theory (e.g., Ogston sieving, reptation models)
• Preparative gel excision workflows where tray flatness (±0.05 mm over 120 mm span) ensures consistent UV exposure and clean band recovery
• High-throughput genotyping assays utilizing multiplexed combs for parallel sample loading across four gel zones

FAQ

Is the DL-SUB02 compatible with ethidium bromide and SYBR-based stains?

Yes—its UV-transparent polymer housing exhibits >92% transmission at 302 nm and is chemically inert to common nucleic acid stains and de-staining solutions.
Can the unit be sterilized using an autoclave?

All non-electrode components—including tray, lid, combs, and buffer chamber—are rated for 121 °C, 20-minute autoclaving cycles per ISO 17665-1.
What is the maximum recommended run time at 120 V?

Continuous operation up to 150 minutes is supported when ambient temperature remains ≤25 °C and ventilation apertures are unobstructed.
Are replacement combs and electrodes available as spare parts?

Yes—DLAB supplies OEM-certified combs (P/N SUB-COMB-XX) and electrode assemblies (P/N SUB-EL-PT) with documented traceability to material certifications.
Does the system include CE or UL certification?

The DL-SUB02 carries CE marking under the Low Voltage Directive 2014/35/EU and EMC Directive 2014/30/EU; UL listing is available upon request for North American distribution partners.
