Export Data
To export the data, select the Edit > Copy > Data menu item. The raw data is
copied to the Windows clipboard in tab-delimited format. The data may be
pasted to spreadsheet applications such as Microsoft Excel or OpenOffice
Calc by selecting the destination cell and selecting Edit>Paste or pressing
Ctrl+V.
5.6.7 Printing
Cryopilot can create a report for the open data file. The report is a snapshot
of the current chart view including the title and legend. The report may be
previewed on-screen or sent to a printer. If you have a PDF print driver such
as Adobe Acrobat installed on your computer, you can save the report to a
PDF file on disk.
To print a report, do one of the following:
Click the Print button on the toolbar
t
Open the File menu and click Print
t
Use the keyboard shortcut Ctrl+P.
t
The Print dialog will appear, prompting you to select the destination printer
and the number of copies. Other settings such as margins and paper size
may be set in Page Setup. Click OK to send the report to the selected
printer.
5.6.8 Profiles
Cryopilot software controls the chiller and the mixer by following a profile.
A profile is a recipe with instructions to change the chiller temperature
setpoint and the mixer mode setpoint (on|off) as a function of time.
Cryopilot software is supplied with a set of standard profiles that are suitable
for many S³ Module and Cryowedge applications.
It may be necessary to create a new profile to suit a specific application.
When designing a new profile, there are several factors to consider:
— Which operations are to be performed – freeze, thaw, or both?
— Are multiple freeze and thaw cycles required?
— What is the initial temperature of the material to be frozen or thawed?
If this is variable, an equilibration step at the beginning of the profile can
improve reproducibility.
— Should the equipment remain running or turn off after the freeze or thaw
is complete?
Adjustment of the freeze and thaw rates is performed empirically. If a lower
endpoint is desired for a freeze, it may be necessary to increase the duration
of the final setpoint or reduce the the temperature adjusted. When trying to
thaw quickly without overshoot, use a high temperature setpoint for a short
duration and then lower the temperature setpoint before the target
temperature is exceeded.
