An electrophoresis apparatus is typically made of a plastic or acrylic gel tank with electrodes built into the tank. The tank is usually filled with a buffer solution, and a gel tray or cassette is inserted into the tank to hold the gel. The gel is where the samples are loaded and separated based on their molecular weights or charges.
The apparatus also includes a power supply unit to provide the electric field needed for the molecules to migrate through the gel. Some electrophoresis apparatus may also have a cooling system to keep the gel and buffer solution at a constant temperature during the separation process.
