Autoclave Browne Control Tubes, Self Chemical Indicating

Best suited for monitoring your dry heat & sterilization of fluid processes the Browne’s tube is a chemical indicator with a heat sensitive solution within a glass tube, which changes from red to green when the tube is subjected to a high temperature for the required length of time.
It is a more reliable indicator of sterility than simple physical indicators such as tapes, as it shows both temperature and time.
