SciCan STATCLAVE G4 - What Happens During a Cycle

What happens during a cycle
The STATCLAVE G4, like all autoclaves, uses various combinations of time, temperature, and pressure to
make up different cycles that are designed to sterilize specific load types. Each cycle is divided into various
phases. Some cycles may have more or less phases depending on the needs of the load type. For example, a
cycle for hollow instruments will have an additional vacuum draw phase before sterilization to ensure steam
penetrates every hollow of every instrument in the load. In another example, a solid unwrapped cycle uses
only one vacuum draw at the start because it does not have instruments with hollow areas that require more
steam penetration.
The following is a description of what devices are ON/OFF and OPEN/CLOSED at each stage of a Hollow
Wrapped cycle, which is a cycle that includes the greatest number of phases.
