If you wish to change the temperature of your samples,
please consider that the time required for temperature
adjustment is prolonged. The farther apart initial and
only
final temperature, the longer it takes for the tempera-
ture to adjust.
The temperature reading does not give the
change in the temperature of the sample
(the temperature display reading is delayed
with respect to the /actual/ sample tempera-
ture change). You can neither witness the
heating nor the cooling of the samples di-
rectly. For critical applications you should
take other precautions to ensure that the
desired temperature is actually reached and
maintained (e.g. by measuring the tempera-
ture immediately after the centrifugation run).
