Electrophoresis Power Supply
Specifications:
The PowerPac 1000 power supply is perfect for most SDS-PAGE applications. In addition, its programmability makes it ideal for running isoelectric focusing, or experiments requiring step changes in electrophoresis conditions. With sufficient voltage for IEF and sufficient current for multiple PAGE gels, plus the control required for reproducibility, it is the ideal power supply for 2-D electrophoresis.

Description:
The Bio-Rad Model 3000xi Computer Controlled Power Supply produces a constant voltage to 3,000 volts, constant current to 300 mA, and constant power to 400 watts. This fully switching, microprocessor controlled unit may be used with any electrophoresis instrument. The high outputs make the Model 3000xi Power Supply ideal for electrofocusing, DNA sequencing, and isotachophoresis. The supply is useful as a general purpose instrument, and is recommended for SDS-PAGE electrophoresis, two-dimensional electrophoresis, native gel electrophoresis, electrophoretic blotting, and DNA/RNA separations. The 3000xi Power Supply is a fully programmable and computerized instrument that incorporates several unique features. The supply offers four operating modes: standard, time, volt-hour, and step. The operator has a choice of running electrophoresis manually, for a set period of time, or for a set number of volt-hours. These parameters can be combined using the step mode. While operating in any one of the four modes, the user simply enters the desired power conditions and begins the run. The operation parameters are displayed on the LCD. Output voltage, current, and power are displayed on the LED display. Electrophoresis running conditions can also be programmed. Up to 10 routines can be saved in the Model 300xi Power Supply's memory, where they can be recalled at any time. This is especially useful when using the special step mode which allows three separate electrophoresis running conditions to be programmed simultaneously. A single gel can then be run safely at three different power conditions without the need for constant monitoring.
Features:
Description:
This power supply is completely transistorized and suitable for either bench or relay rack operation. It is a compact, well-regulated, Constant Voltage/Constant Current supply that will furnish full rated output voltage at the maximum output current or can be continuously adjusted throughout the output range. The front panel current control can be used to establish the output current limit when the supply is used as a constant voltage source and the voltage controls can be used to establish the voltage limit when the supply is used as a constant current source. The supply will automatically crossover from constant voltage to constant current operation and vice versa if the output current or voltage exceeds these preset limits.
