Automated Agarose Gel Electrophoresis System with On-Board Imaging

What is the Automated Agarose Gel Electrophoresis System with On-Board Imaging?

An integrated instrument that loads precast agarose gels, runs the separation and captures an image without user handling of the gel. It suits laboratories that process many PCR products daily and need consistent records.

Overview

The automated agarose system combines a gel tank, power supply, sample loading mechanism and imaging module in one enclosure. Precast gels with fixed well counts are loaded manually or by pipette into a carrier, and the instrument performs electrophoretic injection or conventional loading, controls voltage and run time, then images the gel with UV or blue-light excitation and a camera. Fixed geometry means band positions are comparable between runs, and software reports fragment sizes against an included ladder. Run times are typically 15 to 40 minutes for 12 to 96 samples, and some models accept 96-well precast gels with individual lanes. Because the gel stays in the instrument, operator exposure to stains and UV light is reduced, and image files are stored automatically with run metadata.

How does it work?

In electrophoresis, an electric field drives charged molecules through a gel matrix: nucleic acids carry a negative charge from their phosphate backbone and migrate toward the anode, while their size and conformation determine how quickly they pass through the pores. Agarose gels of 0.5 to 2 percent resolve fragments from about 100 bp to 20 kb, and a buffer such as TAE or TBE carries the current between electrodes. Voltage is set per centimetre of gel length, commonly 5 to 10 V/cm, because higher voltages accelerate runs but heat the gel and blur bands. Sample loading dye adds density and tracking dyes, and a size marker gives fragment lengths by comparison. Detection uses intercalating stains under UV or blue light, or fluorescent labels in chip systems. Denaturing urea-PAGE resolves single-base differences in short oligonucleotides.

What are the key features?

• Precast gels with fixed well counts for reproducible geometry.
• Integrated power supply, tank and imaging module.
• Automatic or assisted sample loading.
• UV or blue-light excitation with camera detection.
• Software sizing against an included ladder.
• Run metadata and image archived automatically.

What are the technical specifications?

A typical automated agarose gel electrophoresis system with on-board imaging configuration offers sample capacity of 12-96 samples per gel, gel format of Precast agarose, 1-2 percent, voltage range of 10-200 V, run time of 15-40 min, buffer volume of 150-500 mL and excitation of UV 302 nm or blue LED 470 nm. Values are indicative of the product class; the exact figures for each configuration are confirmed on the quotation and the calibration documents supplied with the instrument.

Which applications is it used for?

The Automated Agarose Gel Electrophoresis System with On-Board Imaging is used in high-volume PCR product screening, genotyping fragment checks, routine quality control of amplified targets and teaching laboratories with many students. Across the wider Electrophoresis class, laboratories also deploy it for PCR product verification, DNA fragment sizing and restriction mapping and next-generation sequencing library quality control.

Which standards and certifications apply?

Relevant standards and methods include IEC 61010-1, IEC 61010-2-081, IEC 61326-1, ISO 13485 manufacturing and CLSI MM13-A. Certification candidates for this model are CE, ISO 9001 manufacturing and IEC 61010-1 test report; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

Prepare gels in a dedicated area and pour them on a level surface. Use fresh buffer at the recommended dilution, since reused buffer changes pH and conductivity, and check that electrode wires and connectors are clean. Keep the tank covered during runs to limit evaporation and protect operators from UV or electrical hazards, and never touch buffer or electrodes while a run is active. Choose low-toxicity stains where possible and follow local disposal rules for ethidium bromide or other intercalating agents. Clean and rinse tanks after each run to remove residual stain and agarose. Verify power supply calibration and check for cracked gel trays, worn leads and loose lid interlocks at fixed intervals.

How do I select the right Automated Agarose Gel Electrophoresis System with On-Board Imaging?

Select the automated system when PCR products are checked daily and consistent, archived images matter more than the lowest cost per sample. Compare gel format and well count with your throughput, confirm which stains and excitation wavelengths are supported, and check whether precast gels are supplied with a continuing supply agreement.

How does it compare with other Electrophoresis variants?

Match the method to the molecule and the resolution needed. Agarose in a horizontal tank is standard for double-stranded DNA fragments and PCR products, denaturing urea-PAGE for oligonucleotides and single-stranded fragments, and sieving-polymer chip systems for accurate sizing and quantification of many samples. Throughput then decides between manual tanks, multi-channel units and automated systems that combine running and imaging. Consider gel format and well count, buffer volume and cooling, and the detection method, because stains, UV exposure and fluorescence optics differ in sensitivity and safety. For power supplies, check voltage, current and power limits, programmability, and whether constant voltage, constant current or constant power modes are available.
