Super Cooling Point Measuring Service

We use an ALTA (Automatic Lag Time Apparatus) device to cool and freeze your 200µl sample 400 times and then compare to a water sample run 400 times in the same tube. We then provide you with both data sets, the tube and full analysis of the exact super cooling point (SCP) range of your sample.
