REFRIGERATION & TRANSPORTATION - 3M Freeze Watch

The 3M Freeze Watch is an excellent way of monitoring temperature abuse of chemicals and pharmaceutical products such as vaccines and medicines that are damaged by exposure to freezing temperatures during transportation and storage. The Freeze Watch consists of a highly sensitive indicating liquid inside a specially designed ampule. The ampule fractures when exposed to freezing temperatures, irreversibly staining the paper backing of the ampule. The Freeze Watch is available in two temperature ratings, -4ºC/+25ºF and 0ºC/+32ºF
