Methods
Procedural guidelines
We recommend that you carefully review these guidelines before operating the
instrument.
•To ensure safe, reliable operation, always operate the PowerEase™Touch 120W
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™Touch 120W Power Supply at
its maximum electrical load limits. Variations in buer 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 diering salt concentrations or sample buers
at the same time or on the same gel.
Note: Variations in conductivity due to dierences in buer salt concentrations
can aect the run of all the samples run at the same time.
•Properly prepare your samples.

PowerEase™Touch 120W Power Supply User Guide 9

Install the power supply
1. Check the label located on the bottom of the power supply to ensure that the
unit is compatible with locally provided voltage.
2. Place the power supply on a level laboratory bench and position it such that
the On/O switch and the AC inlet at the rear of the power supply are easily
accessible. Keep the area around the power supply clear to ensure proper
ventilation of the unit.
3. Ensure the On/O switch located at the rear of the power supply is in the O
position.
4. Attach the power cord to the AC inlet of the power supply.
5. Plug the power supply into an appropriate electrical outlet (use properly
grounded AC outlets and power cords).
6. Connect the leads from the electrophoresis unit to the power supply by inserting
the positive lead (+) into the red output jack and the negative lead (-) into the
black output jack.
7. Turn the AC power switch at the back of the power supply On.
Programming options
The PowerEase™Touch 120W Power Supply can be programmed to run single-step
and multi-step methods. Up to 100 user defined methods can be saved; up to 20
steps can be saved for each multi-step method.
This power supply is also equipped with several pre-programmed gel electrophoresis
and transfer methods. These methods include voltage and time parameters required
to run and transfer many pre-cast gel products from Thermo Fisher Scientific.
This power unit has a touch sensitive screen, so the selection of on-screen buttons
and parameters is accomplished by touching the screen at the location of the item to
be selected.

Menu navigation
The PowerEase™Touch 120W Power Supply uses several screen icons that simplify
menu navigation.
Icon Description
The Home icon returns to the Home screen (Figure 4).
The back arrow returns to the previous screen.
Left and right arrows indicate that an additional screen is available.
Touch the arrow todisplay the additional screen.
Touch this icon to close the current screen
Touch this icon to navigate to the Settings screen (available on the
Home screen only).
Homescreen
On power up, the Home screen is displayed (see Figure 4).
The Set up run option will appear on the Home screen when the power supply is
switched on for the first time or it if is switched on after running an unsaved custom
method (see below).
The Last run option will appear on the Home screen when the power supply
is switched on after having previously run a saved custom method or a pre-
programmed method. It will also be shown after an un-saved custom method is run
until the power supply is shut o.
Figure 4 Home screens
The following options can be selected from the Home screen:
•Select Set up run to program a new run method.
•Select Custom methods to choose a previously saved run method.
•Select Pre-programmed methods to choose a pre-loaded run method.

Set up a run
1. Switch the power switch located at the rear of the unit to the On position.
2. Touch Set up run.
3. In the Method Type screen touch either Constant voltage, Constant current,
or Constant power.
Figure 5 Method Type screens
4. Edit the run parameters (Volts, Time, Amps, and Watts) by touching the
parameter on the screen to bring up the Run parameter edit screen.
Default maximum values are 300 V, 500 mA, and 120 W.
Note: When using constant voltage or constant power, it is recommended
that the maximum default settings not be changed to avoid unwanted power
limitations during the run.
5. Enter the parameter value required, then touch Enter to advance with the newly
changed run parameter displayed.
6. (Optional) Add or delete extra steps by touching Actions.

7. Touch Start run to begin the run. When the run begins, the Run screen will
display (See Figure 12).
Note: If the run needs to be stopped or paused before completion, touch Stop
or Pause. If run parameters need to be edited during the run, pause the run,
enter changes, then touch Resume. When resumed, the run time will continue
from where it was paused.
8. When the run is complete, the Run Complete screen will be displayed (see
Figure 13).
If the method used is a custom method that has not yet been saved, the Run
Complete screen will display a Save as option. If the method is a saved or
pre-programmed method, the Save as option will not be present. This screen
also displays an option to navigate to the Home screen or to repeat the method.
Constant current
Discontinuous buer systems and, to a lesser extent, continuous systems increase
resistance during the run. With the current limiting setting on the PowerEase™Touch
120W Power Supply, the voltage will increase as resistance increases to satisfy
Ohm’s law (V=IR). If no voltage limit is set and a local fault condition occurs, such as
a poor connection, very high local resistance may cause the voltage to increase to
the maximum capacity of the power supply. This may lead to local overheating and
damage to the electrophoresis cell or create unsafe conditions.
Note: When operating under constant current conditions, it is recommended to set a
voltage limit on the power supply slightly above the maximum expected for the run.
Constant Power
Power is a function of voltage and current P=IV. For a typical gel run at constant
power, the current will decrease during the run, causing the voltage to increase. The
power limiting function may be used when running sequencing gels to remove the
ammonium persulfate from the wells and to heat the gel to an optimal temperature for
DNA separations.
Custom methods
Select Custom Methods on the Home screen to bring up the Custom Methods
screen. From here, the Saved Methods or Method Type screen can be selected (see
Figure 6).
The Saved Methods screen displays methods that have been previously saved
(shown in alphabetical order). Selecting a method brings up the run screen for the
method, allowing the method to be run or edited. The saved method can be edited
by touching any of the run parameter fields.
The Method Type screen displays method types that can be entered (see Figure 5).

5. Edit the method by touching Edit, then save the method using a new name (see
Figure 9) or begin the run by touching Start run.
Note: For a pre-programmed method, only the run time can be edited until it is
saved as a custom method.
IMPORTANT! For a given gel buer type (Tris-Glycine, Bis-Tris, etc.) and run
voltage, gel run times are dependent on several factors. Factors such as running
buer concentration and temperature, type of gel tank used (because of the
electrical path distance between anode and cathode wires), gel separation
gradient and level of running buer above the wells can aect run times to
some degree. So, the exact run time for your gel may be slightly dierent
than the default value given by the pre-programmed method. The default run
times shown in mini gel pre-programmed methods assume the use of the Mini
Gel Tank (Thermo Scientific™(Cat. No. A25977)). Midi gel run times assume
the use of the SureLock™Tandem Midi Gel Tank (Thermo Scientific™(Cat. No.
STM1001)).

For example: The pre-programmed method for running NuPAGE™Bis-Tris gels with
MES running buer is shown in Figure 8.
Once the run has started, the Run screen will display real time parameter values.
