Laboratory gel electrophoresis power supplies are essential devices that provide a stable electric current to drive the migration of biomolecules, such as DNA, RNA, or proteins, through a gel matrix. These power supplies allow precise control of voltage, current, and run time, ensuring consistent and reproducible results. By applying an electric field across the gel, biomolecules move according to their charge and size, enabling their separation for analysis. Gel electrophoresis power supplies are designed with adjustable settings to suit different gel types and experimental requirements. Many feature safety mechanisms such as overload protection and automatic shut-off. They are widely used in molecular biology, genetics, and biochemistry labs for tasks ranging from DNA fragment analysis to protein separation.
