Procedural guidelines

PowerEase ™ Touch 120W Power Supply User Guide
We recommend that you carefully review these guidelines before operating the
instrument.
• To ensure safe, reliable operation, always operate the PowerEase
Power Supply in accordance with the manufacturer's instructions.
• Avoid exposing the power supply to liquids as these may damage the unit and
void the warranty.
•
IMPORTANT! Do not use the PowerEase
its maximum electrical load limits. Variations in buffer conditions can result
in exceeding the power supply's maximum voltage, current, or power output
capacity and produce undesirable variations in performance.
• When using this or any electrophoresis product, we recommend that you adhere
to the protocols given in the electrophoresis product manuals.
For best results:
• We recommend using the Constant Voltage Mode for protein gels or blots.
Note: For most electrophoresis methods, resistance increases throughout the
run. Limiting the voltage allows for an improving margin of safety over time
because the current and power decrease through the run. Also, the same
voltage can be used regardless of the number or the thickenss of gels being
electrophoresed.
• Avoid running samples of widely differing salt concentrations or sample buffers
at the same time or on the same gel.
Note: Variations in conductivity due to differences in buffer salt concentrations
can affect the run of all the samples run at the same time.
• Properly prepare your samples.
