Electrophoresis is a phenomenon in which charged particles move toward an electrode with the opposite charge under the action of an electric field. Under certain pH conditions, each molecule has a specific charge. Within a certain period of time, they move at different speeds in the same electric field, and each concentrate on a specific position to form a tight swimming band. This is how charged particles can The basic principle of separation, analysis and identification using electrophoresis technology. This power supply produces constant voltage, current and power, with an output voltage of up to 600V. It is suitable for electrophoresis experiments of ordinary proteins and nucleic acids, and is suitable for one machine with multiple tanks.
