Electrophoresis Systems & Power Supplies
Electrophoresis remains the workhorse method for separating nucleic acids and proteins by size and charge, and electrophoresis systems and power supplies cover the tanks, trays and supplies that make it work. A gel rig holds the matrix and buffer while a programmable power supply drives a steady voltage or current to move the sample through it. Listings here run from small horizontal DNA tanks to vertical protein rigs and capillary units, all part of the wider molecular biology and genomics range. Buyers fitting out a bench will find matched electrophoresis systems and standalone power supplies, every one from a verified seller with specifications set out clearly.

Electrophoresis Equipment Types
The category splits between the separation hardware and the power that drives it. The main formats below cover routine and specialist separations alike.
Horizontal gel tanks
Horizontal submarine tanks run agarose gels for DNA and RNA size separation, the everyday task in most molecular labs. Tank length and comb options set the sample number and the resolution range you can achieve.
Vertical gel systems
Vertical rigs run polyacrylamide gels for protein separation and high resolution nucleic acid work. Plate size and the number of gels per run are the specifications that decide throughput.
Programmable power supplies
Power supplies deliver regulated constant voltage, current or power with timed run profiles. Output range and the number of parallel outputs determine how many tanks one unit can drive.
Capillary electrophoresis instruments
Capillary systems separate samples in a thin fluid filled capillary for automated, high resolution analysis. They suit fragment sizing and quality checks where gel handling would be too slow.
Brands on Machinery Masters
The manufacturers featured here build horizontal and vertical electrophoresis tanks alongside the regulated power supplies that drive them. Their equipment separates nucleic acids and proteins under repeatable voltage and current. Every name below comes from the Electrophoresis Systems & Power Supplies listings currently available on Machinery Masters, so the strip is rarely the same twice.

Why Choose Machinery Masters
Verified Sellers Only
Every seller is verified before a single listing goes live. Machinery Masters also reviews listings for accuracy, so buyers can commit to high value machinery with confidence.
Global Reach
Listings come from sellers across Europe, North America, and beyond. That reach widens the options past any regional dealer network, and it is often the only way to find discontinued models in good condition.
Flexible Financing Options
Qualifying listings carry financing through partner providers. Terms are shown directly on eligible product pages, spreading the cost instead of draining working capital in one hit.
Direct Seller Contact
No broker sits between the buyer and the seller. Ask about service history, arrange inspections, and negotiate directly with the person who actually knows the machine.
Applications and Uses
This technique appears wherever nucleic acids or proteins need to be checked, sized or separated. These settings show where the systems do their everyday work.
DNA fragment and PCR verification
Labs run PCR products on agarose gels to confirm amplification and check fragment size. It is the quick quality gate before a sample moves to sequencing or cloning.
Protein analysis and Western blotting
Vertical polyacrylamide gels separate proteins ahead of staining or transfer for blotting. Consistent runs here underpin reliable expression and purity assessment.
Quality control in library preparation
Capillary and gel rigs check the size distribution of sequencing libraries before a run. Catching a failed prep at this stage saves costly sequencer time.
Teaching and training laboratories
Horizontal tanks are a staple of teaching labs where students learn separation technique. Robust, simple rigs stand up to repeated student handling.
Benefits from Machinery Masters
The marketplace lists electrophoresis systems and their power supplies side by side.
Tanks and power supplies in one category
Matching a power supply to a tank is easier when both sit in the same listing group. You can assemble a working electrophoresis system without sourcing the parts separately.
Used rigs that stretch a bench budget
Gel tanks and supplies are durable, so a good used rig performs like new for far less. Each listing describes wear and included accessories so the value is clear.
Direct seller contact on combs and leads
You can ask the seller which combs, plates and leads come with a tank before you buy. That saves ordering missing accessories after the unit arrives.
Frequently Asked Questions About Electrophoresis Systems & Power Supplies
Check the tank and lid for cracks and crazing, since stress lines can leak buffer or fail under voltage. Confirm the electrode wires are intact and the safety interlock still cuts power when the lid lifts. Ask which combs and casting trays are included, as replacements add cost if they are missing.
Check the supply's voltage and current range covers the runs you do, from low voltage agarose to higher voltage protein gels. Count the output pairs if you want to drive more than one tank at once. A supply with programmable timed profiles is worth having for reproducible runs.
The lid interlock that cuts high voltage when the tank is opened is a critical safety feature. Ask the seller to confirm it operates, and test it yourself on arrival before routine use. A unit with a defeated or broken interlock should not go into service until it is repaired.
Horizontal tanks handle agarose DNA gels while vertical rigs are made for polyacrylamide protein gels, so most labs keep both. Some vertical rigs can run high resolution nucleic acid gels as well. Decide your main workload first, then add the second format as need grows.
Financing is available on qualifying listings, though tanks and supplies are often modest enough to buy outright. Where the option applies it is shown on the listing. For a larger capillary instrument it can be worth discussing with the seller.
