Spring is a long way off, and you may still be spending several
minutes each day scraping the ice off your car. So don’t forget
about your Anprolene sterilizer! As most of you know, your Anprolene
sterilizer should be kept at room temperature in a controlled environment
of at least 68o F and 35 percent humidity to ensure proper performance.
Until temperatures outside warm up, you must take action to make
sure the environment for your sterilizer stays regulated. Common
problems relating to cold weather include:
indicators don’t change color.
Color indicators, such as the AN85 Exposure Indicator Strip, are
not complete indicators of sterility. They are specifically designed
to confirm the presence of Ethylene oxide. The indicator turns blue
in the presence of EtO, and it normally does so quickly. If it does
not turn blue over a 14-hour period, there may be a serious problem
in the sterilization environment.
don’t reach the line.
The AN87 Dosimeter confirms that the right time, temperature and
EtO concentration parameters were achieved during the sterilization
process. With an understanding of these three variables, you can
determine which one is causing the problem. If the Dosimeter was
exposed to the correct cycle time, and the bag was sealed properly, then the problem is likely
related to temperature. During colder periods, you may
not realize how far the temperature has fallen inside your sterilizer, especially during the night.
The AN80 Steritest is a biological indicator that contains over
one million highly resistant bacteria
spores. In low humidity environments, these spores can become desiccated
and impossible to kill. Of course, during winter months, low humidity
is a common problem. Proper storage of your biological indicators
will keep them functioning properly.
tips to remember this winter about your Anprolene sterilizer:
EtO must maintain a minimum temperature of 68 degrees
to sterilize. Check the environment in which your sterilizer is
placed. Please remember that it is colder at night than during the
hustle and bustle of your daily practice.
to see if outside air is entering the sterilizer exhaust line when the
unit is not in use. If this is the case, warm the interior of the
sterilizer up by opening the door for an hour before
running the cycle.
deliver dry heat to a room. Humidichips help to
stabilize humidity in the sterilization bag.
Dosimeters in each load to check that the parameters
of sterilization (time, temperature, and gas concentration) have
Biological Indicators in your load as the true
test of sterility.
