Method
•
Place the Cooling Elements in the Freezer after it has allowed to reach its operating
temperature. Orientate as follows:
Freezer, Standard - Orientate as they are in the COOLBOX Base
Freezer, Bulk - Place Cooling Elements in 2 layers. The bottom layer is placed
upside down and the top layer the correct way up
•
It is important to orientate the Cooling Elements correctly in the freezer. Incorrect
orientation can result in the elements bulging during the freezing process, which can
make it difficult or impossible to locate them correctly in the COOLBOX base
•
Leave the cooling elements to become fully frozen. Starting with the cooling elements
at 20°C this can take up to 18 hours
•
Remove the Cooling Elements from the freezer place them in a nominal 20°C ambient
and orientate them with a suitable thermometer typically as shown in the diagram on
the next page (where multiple pairs of Cooling Elements are being conditioned only
one pair needs to be monitored)
•
Leave the Cooling Elements to warm up to 0°C
•
If the ambient temperature where the Sampler is to be deployed is expected to be in
the range
– 10°C to 0°C, leave the Cooling Elements for a further 30 minutes before
deploying, otherwise deploy immediately in the COOLBOX Base
