This device is designed to provide a constant voltage, power and current for applications during the process of electrophoresis. It works properly with dodeca cells and is very appropriate in blotting in electrophoresis. The device has four sets of output jacks, these jacks can support the connection of four electrophoresis cells in parallel at the same time.
Power can be adjusted within the increments of 1W from time to time within the range of 1 to 500 Watts. Further, the operator can adjust the voltage before or during operations within the range of 1V from ten volts to five hundred volts. With regard to current the increment intervals is 1mA within the range of 10 to 2500 mA.
BioRad PowerPac Universal Power Supply is equipped with an LCD screen displays which indicates all run parameters simultaneously. It has a high capacity for storage that can accommodate nine user defined methods. The constant value feature is also supported with an automatic crossover that takes effect when need arises.
Further, the device is enabled to have a sensitive detection of no load, change in rapid resistance, ground leaks, and changes in parameters among others. With the programmable feature of up to nine steps, the device enables the operator to operate it within a preset duration or within the range required for a particular experiment. The device also has the data transfer software that can be used by the operator if he prefers it. The same can be used for transfer of data to PDA and/or PC.
