High Temperature Decontamination
High temperature decontamination is designed to heat the internal chamber to
120°C, maintain that temperature for 4 hours, and then allow the chamber to cool
down to 37
º
C (or the programmed temperature) when normal control takes over.
The incubator must be cleaned, decontaminated chemically, and dried thoroughly
before starting the process. The inner and outer door seals must be cleaned
carefully and all surfaces wiped over with decontaminant (see the instructions in
Section 6,
Cleaning & Disinfecting
).
