Small packs can be placed directly on the tray in an upright position.
They should not be touching each other or the Chamber walls. There
should be about ½
” to 1” between packs for proper steam
circulation.

Place a sterilization indicator on each tray and/or inside each wrapped
cassette.

At least once a week use a biological spore test (Bacillus
Stearothermophilus) in any load to ensure proper sterilization (be
aware testing standards may vary). Always follow the spore test
manufacturer’s instruction.

If spotting is detected on the instruments, it is necessary to determine if
the spot is dirt or oxidation. The first step would be to use an ordinary
eraser to remove the spot. If there is no pitting under the spot, then the
spot is only dirt. Dirt spots on an instrument may be an indication that
the autoclave needs to be cleaned or that the instruments were not
adequately cleaned prior to sterilization. If removal of the spot reveals
pitting, then the spot is most likely oxidation. oxidation spots on an
instrument are not uncommon on inexpensive instruments. It may also
be an indication that the instruments were rinsed in tap water with a
high mineral content. These minerals when exposed to high
temperature and steam will accelerate the oxidation of the metal. One
suggestion would be to final rinse the instruments in a distilled water
bath and pat dry to absorb residual water and minerals.

If the instruments exhibit a discoloration this can be due to the mixing
of carbon steel and stainless steel. When these two metals come into
contact with each other electrolysis occurs that breaks down the metal.
The best solution is to separately wrap the carbon steel instrument to
insulate it from other instruments on the tray and from the tray itself.
