7.2 Sequences
The DCU3 - system can store up to 24 sequences which can be configured according to the type and
specifications of the fermentor system. The programs can consider, for instance, empty vessel sterili-
zation, medium sterilization, sterilization of transfer installations, intermediate sterilization for air inlet
filter and for exhaust filter, etc. The structure of sterilization programs, such as step change conditions
for single steps and process outputs during the steps, can be adapted to different requirements.
 Detailed descriptions of sequences, such as the sterilization of the culture vessel or of pe-
ripheral equipment can either be supplied in the supplement of this manual, in the configura-
tion documentation of the delivered DCU3 - system or in other documentation delivered ex-
tra with the fermentor system.
Note: For fermentor systems with autoclaveable culture vessels and peripherals (such as
the BIOSTAT
®
B-DCU, BIOSTAT
®
MD, BIOSTAT
®
BF or BIOSTAT
®
Q, for instance)
no sterilization function is available.
