Multi-Channel Agarose Gel Electrophoresis System

What is the Multi-Channel Agarose Gel Electrophoresis System?

A horizontal tank with multiple independent lanes, trays or sub-cells, letting several users or protocols run at the same time. It keeps equipment cost low while handling moderate screening workloads in shared laboratories.

Overview

The multi-channel tank divides one buffer chamber into two to four sub-cells or provides multiple parallel trays with independent electrode pairs. Each section can run at its own voltage when separate leads are used, so a 20-minute PCR check and a 90-minute digest analysis can proceed in parallel. Total well capacity ranges from 24 to 96 wells across the sections, and gel trays are usually UV-transparent acrylic with fixed comb positions and casting gates. Buffer volume of 300 to 1,000 mL is common, and cooling is passive unless a recirculation port is fitted. Multichannel pipettes can load a full row at once, which reduces handling time. The design suits shared laboratories where several small runs happen during a day, and it costs less than an automated system.

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?

• Two to four independent sub-cells or parallel trays.
• Separate leads allow different voltages per section.
• Total capacity of 24 to 96 wells.
• UV-transparent acrylic trays with fixed combs.
• Compatible with multichannel pipette loading.
• Optional buffer recirculation port for longer runs.

What are the technical specifications?

A typical multi-channel agarose gel electrophoresis system configuration offers number of sections of 2-4 independent sub-cells, well capacity of 24-96 wells total, gel size of 7 cm × 10 cm to 15 cm × 20 cm, voltage range of 10-300 V, separately controlled, buffer volume of 300-1,000 mL and comb options of 0.75, 1.0, 1.5 mm thick, 8-20 teeth. 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 Multi-Channel Agarose Gel Electrophoresis System is used in parallel PCR product checks, restriction digest analysis by several users, teaching laboratories with multiple groups and routine fragment screening. 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 Multi-Channel Agarose Gel Electrophoresis System?

Select the multi-channel tank for shared laboratories with moderate daily throughput, where several short runs must happen in parallel. Compare section count, well capacity and maximum voltage, and confirm that the tank fits your largest gel format. Check comb options, whether the lid carries separate leads and if you need buffer recirculation.

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.
