STERILISE CYCLE
The sterilise cycle has now started.
A temperature graph is plotted to show
the duration of the cycle. The y-axis
automatically changes its scale to 205 °C

Section 8.5
The sterilise cycle consists of 3 distinct phases. They are:
x
Heat up.
During the heat up phase, maximum power is applied to
the heating elements. CO
2
control is disabled to protect the
sensor and the door locks are activated.
x
2 hour dwell.
The dwell phase starts once the chamber temperature
reaches 200 °C.
Heater power is automatically reduced to regulate the
temperature at 200 °C.
x
Cool down.
After 2 hours at 200 °C power is removed from the heaters
and the cooling phase begins. The chamber is allowed to
cool naturally. When the chamber temperature reaches
38 °C the door locks are deactivated and CO
2
control is
enabled.
The time taken for a full sterilisation cycle is
dependent on the cool down phase.
As cooling relies on the heat loss through the chamber walls
the time taken is affected by the location of the incubator
and the ambient temperature.
So, an incubator placed under a worktop will take longer to
cool than a freestanding incubator on a worktop.
We recommend that you carry out the sterilise cycle at the
end of a working day. That way, when you return to work in
the morning the incubator will be ready for you to use.

HIGH TEMPERATURE
STERILISATION
Risk of damage to unit.
The Comfort 190 is not intended to be used as
an autoclave and must not be used for sterilising
any other equipment.
Only the shelves, racking and water tray can be
left inside the incubator during sterilisation.
Risk of injury. Risk of burning. Internal surfaces
reach 200 °C
The Comfort 190S incubator is equipped with a high
temperature sterilisation function. This raises the chamber
temperature to 200 °C for 2 hours.
Independent evaluation has shown this to be effective
against all spores and bacteria commonly associated with
laboratory incubator contamination.
