In general, the following applies for the cooling:

Decreasing the temperature of the coolant will result in
lower final temperatures and higher cooling rates (the
final temperature will be reached faster).
 Increasing the flow through volume will result in lower
final temperatures and higher cooling rates.
Example:
With a preset temperature of 20C at the Thermo Fisher
Scientific Haake circulator DC50--K20, the Peltier system will
reach max. cooling rates up to 1 K/s and a final temperature
of 0C. Starting at +20C the final temperature of 0C will
be reached after about 6 minutes.
 For a given ambient or room temperature there is a low-
est temperature which can be reached. This is usually
about 0C.
 lower temperature values can be realized if the loss of
cooling capacity is reduced by insulation.
