Description

Biorad PowerPac 300 Electrophoresis Power Supply supplies constant current and voltage during the electrophoresis process. The instruments used in the process receive constant voltage and current during the process of blotting and electrophoresis to give good output and to work devoid of power problems and faults. The device is adjustable in many dimensions: The voltage output of the device is designed to be capable of adjustment at an interval of one volt; the same can be adjusted from ten volts to three hundred volts. The current supply is also adjustable at the rate or interval of one milliAmp, from four volts to four hundred milliAmps. The device gives a power output of 75 watts at maximum.

The unit can operate properly with four electrophoresis cells connected in parallel and run simultaneously. When the unit is turned on, it will operate with the default current and voltage limits. The values that will be recorded at the display are constant values in the default setting.

To prevent damage to the electrophoresis cells, the device is enabled to cross over to constant current or voltage, depending on the values first reached. For efficiency, the unit is designed in such a way that upon attainment of the maximum set value of a non-constant parameter without the maximum power capacity being reached, the device will switch the power hence the non-constant parameter will be made the new constant in that operation.

The device is fitted with a time controller, a 3-digit LED display for monitoring the values, it has a detector of non-load conditions and any rapid changes in the device, a viewing angle adjustment feature, an automatic process completion when the same was interrupted by power. This must be enabled by the operator.
