6.3. Running a profile
Profiles can be set up and run using the Monitor page.
Figure 17: Software: Choosing Profile
6.3.1. Selecting the profile & details
Before running a cooling profile check the following are correct:
•The cooling profile
•The logging interval
•The name and storage folder of the log file
6.3.1.1. Choosing the profile to run
In the Profile Details window choose a profile from those loaded on the CRF-1 from the
Profile options (e.g. Cryo1 in Figure 17). The specific temperature details of the chosen
profile can be viewed by clicking on the View Details box. This will help ensure you have
chosen the correct profile before it is run.
6.3.1.2. Setting the log file parameters
Set the Log Interval, Log Directory and Log Filename in the Profile Details window. The
log interval is normally set at 2 seconds for typical cryopreservation applications with run
lengths up to approximately three hours (e.g. stem cell, blastocysts, mouse embryo, somatic
cells etc).
Note: Shorter logging intervals and long cryopreservation profiles result in very large log files
that may not provide any more information. For applications that need prolonged freezing
stages, the interval can be increased to up to 60 minutes between logging points dependent
on application.

CRF-1 Operating Manual Page 19 of 60 33801-V4 DMN S90
The location and filename of the directory where the log files are stored should be confirmed
before starting the run.
Note: The default settings for the profile details can be changed using the Software Config
page (see Section 6.7 for further details)
6.3.2. Running the profile
When all of the settings are correct and the CRF-1 is at the start temperature (indicated by
the ‘Ready’ light being on) you are ready to perform a cooling run. Load the samples onto the
cooling plate according to the appropriate protocol and click Start Profile.
Note: Clicking the Stop Profile button will abort the run and the CRF-1 will return to the start
temperature.
6.4. Creating reports
6.4.1. Generating a run report
6.4.1.1. Report formats
The software stores log files and an event log in an encrypted GEF file format. This ensures
that source files cannot be altered without detection and are suitable for validation and
archiving purposes.
Four reports can be produced from the encrypted log file using the Report page:
•PDF Detailed Report: Includes a graph of the actual and set temperatures, a profile
summary section, a notes box for handwritten information and a quality control box
which gives a detailed analysis of each profile segment.
•PDF Standard Report: As the PDF Detailed Report except with no quality control
analysis box.
•TSV Detailed Report: Includes a profile summary section and a quality control box
which gives a detailed analysis of each profile segment. Suitable for a program
capable of displaying TSV (Tab Separated Variable) data such as Excel.
•TSV Standard Report: As the TSV Detailed Report except with no quality control
analysis box.
6.4.1.2. Generating PDF reports
Click PDF Standard Report or PDF Detailed Report to produce a PDF report. Browse to an
GEF log file using the dialog box which appears then click Open (see Figure 18). The
relevant report will appear in the viewing area. The report can be saved or printed by clicking
on the Save or Print buttons at the foot of the page.
