For the NG-ISCC Series, the cooling bath is intended to be filled with ethanol or another non-freezing solution suitable for the target conditioning temperature.

In practice, the “right” cooling medium depends on your lowest setpoint, how quickly you need the bath to stabilize, and your facility’s EHS requirements for handling and storing flammable liquids. The goal is a stable, well-circulating bath fluid that will not freeze, thicken excessively, or create inconsistent specimen temperatures during the soak.

When evaluating an alternate non-freezing solution, confirm these basics before use:

  • Freezing point margin versus your lowest conditioning temperature
  • Viscosity at temperature (to maintain effective circulation)
  • Chemical compatibility with the chamber and accessories
  • Safety considerations such as flammability, ventilation, and disposal
