7. RUNNING A STERILIZATION CYCLE
7.1 THE AVAILABLE STERILIZATION CYCLES
The following table shows the available sterilization cycles and the different type of loads that can be
processed in the sterilizer. In total there are 3 type B sterilization cycles available; all offering the ECO-
DRY feature (see below).
Note: Certain cycles may have been be de-activated in accordance with local requirements or guidelines
B UNIVERSAL 134
(with ECO-Dry)
This is the factory setting default sterilization cycle of the sterilizer (a different
default cycle can be set by the user). The cycle is a type B sterilization cycle
(suitable for all types of loads; solid, porous, hollow A and B; unwrapped,
bagged, single or double wrapped) that features a pre-vacuum phase, a pla-
teau time (sterilization or holding time) of 4 minutes at a temperature of
134°C and a pulsed vacuum drying phase. See the tab le on the following
page for further details.
B PRION 134
(with ECO-Dry)
This is a special sterilization cycle in accordance with the WHO’s recommen-
dations on CJD (Creutzfeld Jakob Disease) for a longer sterilization plateau.
The cycle is a type B sterilization cycle (suitable for all types of loads; solid,
porous, hollow A and B; unwrapped, bagged, single or double wrapped) that
features a pre-vacuum phase, a plateau time (sterilization or holding time) of
18 minutes at a temperature of 134°C and a pulsed v acuum drying phase.
See the table on the following page for further details.
B UNIVERSAL 121
This is a low-temperature sterilization cycle (121°C) primarily designed to ste-
rilize items that cannot withstand the temperature of 134°C (plastics, textiles).
The cycle is a type B sterilization cycle (suitable for all types of loads; solid,
porous, hollow A and B; unwrapped, bagged, single or double wrapped) that
features a plateau time (sterilization or holding time) of 15 minutes at a tem-
perature of 121°C and a pulsed vacuum drying phase. See the table on the
following page for further details.
ECO-Dry FEATURE
When selecting a “B-UNIVERSAL 134” or a “B-PRION 134” cycle, the
sterilizer automatically adjusts the time of the drying phase to the
amount of load placed, thus delivering the shortest cycle duration
possible at all times. For further details see § 7.1.2.
