Sterilizer Cycle
Amsco Evolution Medium Steam Sterilizers are shipped with factory-
set cycle values. The cycle sequence for these cycles are given in
S
ECTION 6.8, PREVAC CYCLE OPERATION, PAGE 6-9. Refer to Table 6-4,
below, for factory set, qualified cycle settings.
The sterilization cycles listed in Table 6-4 have been validated using
techniques documented in EN 285:2006. If different cycle
parameters (sterilize time and dry time only) other than those in
Table 6-4 are required, it is the responsibility of the healthcare
facility to validate the cycle. Reference EN ISO 17665-1:2006 for a
guide to validating sterilization cycles and to ensure drying
efficiencies are met.
NOTE: Contact STERIS for information on a wide range of
education/training programs designed to meet the educational needs
of healthcare facilities.
