Provides optimal incubation conditions for the accurate readout of 3M Attest Biological Indicators. Since the growth of each test organism is temperature dependent, it is critical that the appropriate Attest biological indicator be used with the correct Attest incubator. Each Attest incubator is pre‑set at the appropriate temperature to promote growth of the test organism. The incubator’s internal temperatures are rigidly controlled to 56°C+/‑2°C and automatically maintained.
