Room Disinfection

Model CD87-200G - Uv Dosimeter for Uv-C Radiation Disinfection

It has been demonstrated that many microorganisms can be inactivated by continuous UV-C radiation. UV-C radiation is absorbed by DNA and RNA, causing changes in their structures and preventing their replication. The radiation dose required to achieve a microbial load reduction depends not only on the particular microorganism, but also on additional factors like radiation intensity (power) of the emitting source, distance between emitting source and surface, and time of exposure. Furthermore, surfaces that only receive radiation by reflection, get lower doses that may not be sufficient to incativate the pathogenic microorganisms present. Considering all this, it is of utmost importance to control that all surfaces to be disinfected, receive the minimum radiation dose required.

Model BT31 - Spore Ampoule for Dry Heat Sterilization Processes

The Bionova® BT31 Biological Indicator is designed for the control of Dry Heat sterilization processes. It is compatible with extremely high temperatures generated during depyrogenation cycles and sterilization processes in ovens and dry heat tunnels. The contents of the ampoule should be incubated in the Bionova® MC1030-2 culture medium tube or a culture medium suitable for the growth of Bacillus atrophaeus ATCC 9372. If the sterilization process was unsuccessful, the indicator medium will change from blue to yellow after incubation at 37±2 °C, thus indicating the presence of living spores. If the sterilization process was successful, the indicator medium will remain blue, being the final reading taken after 72 hours of the indicator’s incubation at 37±2 °C.
