If we want to cool the sample, the pump is placed in a
styrofoam contaijer full of ice. I place a thermomnemter in
the sample tube and add salt to the melting ice until the
sample is being cooled to the correct temperature.
If we want to warm the sample, the pump is placed in a
a heated water bath from the lab. and again the temperature
adjusted until the sample is at the desired temperature
(usually 37C).
