STERIS’ Bowie Dick tests comines Browne Intelligent Ink Technology and the original Bowie Dick concept. The Browne 121 ˚C TST Bowie Dick Test Pack has a maximum plateau of 8.3 minutes. This enables the sensitivity of a 121 ˚C Bowie Dick Test to be comparable to that of a 134 ˚C Bowie Dick Test. Note that these are available for both 134 and 121 degrees cycles.
