Can a regular freezer be used to prep and store lab freezer temperature panels? L Can a regular freezer be used to prep and store lab freezer temperature panels? Yes, but to get the panels truly hard, the freezer must maintain a temperature lower than -30°C. Otherwise, the panel will be at the temperature of the freezer (in a liquid state) and just won’t last as long.
