Description
The Bio-Rad PowerPac 300 is an electrophoresis power supply that provides constant voltage or constant current to instruments used in gel electrophoresis and blotting. It sits a step above the PowerPac Basic in both output range and connectivity, offering a higher maximum voltage and current ceiling along with the ability to connect up to four electrophoresis cells in parallel, making it well suited for labs running multiple gels or blots simultaneously. Like other units in the PowerPac line, it automatically switches between constant voltage and constant current modes to protect connected cells from damage, and its compact, stackable housing makes it easy to integrate into crowded lab benches or shared equipment stations. With programmable timer control, a digital display, and built-in safety detection features, the PowerPac 300 is a dependable, general-purpose choice for labs that need more flexibility and capacity than an entry-level power supply can offer, without stepping up to a high-end research-grade unit.
Features:
- Dual Output Modes: Programmable constant voltage or constant current, with automatic crossover to protect the electrophoresis cell
