The CBS Scientific EPS-300X Electrophoresis Power Supply is a compact laboratory power supply designed for electrophoresis applications in molecular biology, biotechnology, clinical research, and life-science laboratories. The model visible in the photograph is clearly identified as EPS-300X and is manufactured by C.B.S. Scientific Company. The unit features a digital display, adjustable control buttons, constant-mode selection, run/stop control, and multiple high-voltage output terminals for electrophoresis equipment.

The EPS-300X provides programmable voltage and current control and is designed with a compact, stackable format suitable for benchtop laboratory use. According to published specifications, it supports an output voltage range of 10–300 V and output current of 4–500 mA, with 1 V and 1 mA adjustment steps respectively. The unit supports constant-voltage and constant-current operation and includes a timer function for controlled electrophoresis runs.

The photographed unit shows noticeable cosmetic wear, dirt, discoloration, and surface marks consistent with used laboratory equipment. The digital display and front-panel controls are present, but operational performance, output accuracy, internal condition, and electrical safety should be verified before use.

Applications

The CBS Scientific EPS-300X is primarily intended for supplying controlled electrical power to electrophoresis systems used for separation and analysis of biological molecules. Typical applications include agarose gel electrophoresis, DNA and RNA separation, protein electrophoresis, molecular biology research, and other laboratory electrophoretic techniques.

Its adjustable voltage and current operation allows researchers to select appropriate electrical conditions for different electrophoresis setups. The programmable timer can also be used for timed laboratory runs, while the compact design makes the unit suitable for research laboratories, educational institutions, biotechnology facilities, and clinical or analytical laboratories.

Benefits of Refurbished Laboratory Equipment

Purchasing a refurbished CBS Scientific EPS-300X can provide laboratories with a practical and economical electrophoresis power-supply solution compared with purchasing a new equivalent unit. Its compact design, adjustable voltage/current operation, and timer functionality make it suitable for routine electrophoresis workflows where controlled electrical output is required.

Refurbished laboratory equipment can also be useful for educational laboratories, research facilities, biotechnology laboratories, and organizations maintaining existing electrophoresis systems. Proper inspection and testing can help determine whether the unit is suitable for the intended application while reducing equipment acquisition costs.

Additional Information

The photographed instrument is offered as a refurbished CBS Scientific EPS-300X Electrophoresis Power Supply. The exterior shows significant cosmetic wear, staining, scratches, and accumulated dirt from previous laboratory use. The exact condition of the internal electronics, output calibration, cooling system, display accuracy, and safety circuits should be verified before operation.

The photograph also shows the EPS-300X positioned on top of another Thermo Scientific laboratory instrument. The listing is for the CBS Scientific EPS-300X power supply only unless the accompanying equipment is specifically included in the sale. Power leads, electrophoresis chambers, cables, accessories, and other components should be confirmed separately before purchase.
