C.B.S. Scientific EPS-300 X Electrophoresis Power Supply – 300V, 500mA, 90W

The C.B.S. Scientific EPS-300 X Electrophoresis Power Supply is a programmable laboratory power supply designed to provide controlled electrical output for a wide range of electrophoresis applications. Manufactured by C.B.S. Scientific, this compact and versatile unit is suitable for molecular biology laboratories, biotechnology research facilities, educational institutions, pharmaceutical laboratories, and scientific research environments.

The EPS-300 X is designed to deliver adjustable voltage and current for electrophoretic separation techniques. It supports a maximum output voltage of 300 V, maximum output current of 500 mA, and maximum output power of 90 W. These operating capabilities make it suitable for routine laboratory procedures involving DNA, RNA, and protein separation.

Electrophoresis is an essential laboratory technique used to separate biological molecules according to their size, charge, and other physical characteristics. During the process, an electrical field is applied across a gel or supporting medium, allowing charged molecules to migrate toward the oppositely charged electrode. The EPS-300 X supplies the controlled electrical power required for these laboratory procedures.

One of the important features of this power supply is its constant voltage and constant current operating modes. Users can select the desired operating parameter according to their experimental requirements. The instrument automatically adjusts its output behavior when the electrical resistance of the connected electrophoresis system changes, helping maintain the programmed operating limits.

The EPS-300 X features a digital red LED display that allows users to monitor operating parameters. Its membrane keypad includes up and down adjustment buttons and a mode selection function for setting and viewing voltage, current, and time. The simple interface makes the instrument convenient for routine laboratory operation.

The unit also includes an integrated programmable timer that supports run durations from 1 to 1440 minutes, equivalent to 24 hours. This function allows researchers to establish the required running period for electrophoresis experiments. Continuous operation is also supported when required by the experimental procedure.

Another important design feature is the provision of four pairs of color-coded output terminals. These recessed output connections accept standard 4 mm plugs and operate in parallel. The multiple output connections provide flexibility when connecting compatible electrophoresis cells and apparatus.

The EPS-300 X is suitable for several electrophoresis techniques, including standard PAGE gel electrophoresis, multiple mini-PAGE gel applications, horizontal agarose gel electrophoresis, vertical agarose gel electrophoresis, semidry transfer, and mini-gel tank transfer. Its adjustable voltage and current settings allow researchers to select appropriate operating conditions for different laboratory protocols.

Safety is an important consideration in electrophoresis equipment. The C.B.S. Scientific EPS-300 X incorporates protective functions such as no-load detection, sudden load-change protection, overvoltage protection, and automatic power failure recovery. These functions help protect the connected electrophoresis system and support more reliable laboratory operation.

The power supply features a compact, lightweight, and stackable construction, making it suitable for laboratories where bench space is limited. Its dimensions are approximately 320 × 240 × 73 mm, with a net weight of approximately 2.4 kg. The universal input power design supports 100–240 VAC at 50–60 Hz, allowing use with compatible electrical supplies in different regions.

The C.B.S. Scientific EPS-300 X is an appropriate choice for laboratories looking for a programmable electrophoresis power supply with adjustable voltage and current settings, timer functionality, multiple output connections, and integrated safety features. It provides the essential electrical control required for routine molecular biology and biochemical research procedures.

Whether used for DNA electrophoresis, protein separation, agarose gel electrophoresis, or compatible electrophoretic transfer applications, the EPS-300 X offers a practical laboratory power supply solution. Its compact design, straightforward controls, and programmable operating functions make it a useful instrument for research laboratories, biotechnology facilities, academic institutions, and pharmaceutical testing environments.

Before purchasing, users should verify the equipment's physical condition, electrical functionality, output accuracy, and compatibility with their electrophoresis apparatus.
