PowerPac 300 by Bio-Rad: Reliable, Flexible Power Supply for Electrophoresis and Blotting

The Bio-Rad PowerPac 300 is a compact, efficient power supply designed specifically for electrophoresis and blotting applications. As part of Bio-Rad’s PowerPac line, it offers researchers high levels of precision and control. Whether you're running gels or performing blotting procedures, the PowerPac 300 ensures consistent, reproducible results, making it an invaluable tool for any molecular biology or protein research lab.

The PowerPac 300 offers a wide range of adjustable outputs. Its voltage output can be precisely set from 10 to 300 volts in 1-volt increments, while the current output is adjustable from 4 to 400 mA in 1-mA increments, allowing for fine control during your experiments. With a maximum power output of 75 watts, it provides enough capacity to handle a variety of applications while maintaining efficiency.

One of the key features of the PowerPac 300 is its ability to operate in constant voltage or constant current mode, with automatic crossover between the two. This flexibility ensures that the power supply maintains the desired parameter throughout the entire run, even if experimental conditions change. This adaptability is particularly important in applications like SDS-PAGE or DNA agarose gel electrophoresis, where precise control over electrical parameters is critical.

Safety and usability are central to the PowerPac 300’s design. The unit automatically detects no-load conditions and responds to rapid changes in resistance, protecting both the power supply and connected equipment. In the event of a power failure, the PowerPac 300 can automatically complete the interrupted run, provided this feature is user-enabled. This reduces the risk of losing data or damaging samples due to unexpected power interruptions, offering peace of mind during extended experiments.

The 3-digit LED display allows for easy monitoring of voltage, current, and time, giving users real-time feedback on experimental conditions. Timer control is also built-in, ensuring that your run can be precisely timed and terminated automatically when necessary. Additionally, the PowerPac 300 features a viewing angle adjustment for ease of use in different laboratory settings.

Designed to maximize space efficiency, the unit is stackable, making it ideal for labs where bench space is at a premium. Its compact design, measuring just 29 cm long, 21 cm wide, and 8 cm high, and light weight of 1.8 kg make it easy to move and fit into various setups.

Beyond the core specifications, the PowerPac 300 is also engineered to meet stringent safety and quality standards. It conforms to CE standards for emissions and immunity, and its TUV EMC certification ensures it operates within accepted electromagnetic compatibility parameters. The device has been tested at 220 V to ensure safety and reliability.

Bio-Rad has also equipped the PowerPac 300 with four recessed female banana jack terminals, floating in parallel, providing secure and reliable connections for all your electrophoresis applications. The unit operates reliably within a broad range of environmental conditions, with an operating temperature range of 0°C to 40°C and humidity tolerance up to 95%, provided no condensation is present.

The PowerPac 300 is ideal for researchers who need a versatile, safe, and user-friendly power supply for electrophoresis and blotting applications. With its advanced features and robust safety protocols, it ensures precise and consistent results, making it a valuable addition to any laboratory.
