The rack slowly warms, taking approximately 4 hours before there is a complete color change.

Measures 146 mm L x 105 mm W x 70 mm H.
Freeze inverted for a minimum of 8 hours at -20°C before use. Color changes at 7°C. Rack will not perform to specification if it is not frozen at -20°C. Leave lid in place when in use.
