3.2 View Menu
In the View menu there are two sub-menus: the View and Graph Type sub-menu.
View sub-menu:
• Show Puller 560 Control Panel - Show or hide 560TP control panel.
• Show Experiment List Panel - Show or hide the Experiment List containing all the experiments performed.
Graph Type sub-menu:
• Selection of the Graph Type - MyoPULL can display the experiment as Displacement-Force Graphs or Strain - Stress Graphs.
In Displacement-Force Graphs the x-axis is shown in µm and the Y-axis in mN. In the Strain - Stress Graphs the X-axis is
Strain and the Y-axis is Stress (mN/mm2).
3.3 Experimental setup
The 560TP is a system specifically designed to perform tensile strength tests.
1. Mount the sample you wish to test tensile strength for between the motor (via the force transducer) and the jaw.
2. Enter the µm the tissue is to be stretched in Pull Range .
3. Enter the velocity (0-150µm/sec) the motor is to use during the stretch in Target Velocity .
4. If you want to repeat a stretch enter the micro-positioner position in the Start Position box and press Enter.
5. If you want to display the experiment as a Stress - Strain Graph enter the values for segments length, segment thickness
and segment diameter, all in µm.
6. Select how the experiment should be displayed; either as a Force-Displacement Graph or a Stress - Strain Graph .
7. To start the Pull experiment press Start Pull. The force that the sample is exposed to and the motor’s present position is
plotted by the MyoPULL software, thereby creating a Force-Displacement Curve as seen in figure 3.3 on next page or as a
Stress - Strain Curve as shown in figure 3.4 on next page.
8. After a completed Pull experiment MyoPULL automatically transfers the maximum force or stress value to the Experiment
List where the Micrometer Position , Max Force and Max Stress will be recorded.
