BIOLOGICAL TESTING IN YOUR STERILIZER
The Centers for Disease Control, the American Dental Association and Dentronix recommend
testing your sterilizer with biological indicators at least once per week. Spore strips compatible with
the dry heat process (live Bacillus spores) should be used (i.e. DPS-012 PassPort Monitoring Service,
DEMS-012 Monitoring Service or DCS-020 SporView Culture Set). Your DDS 7000 has been validated
according to the requirements of ANSI/AAMI ST50:2010, “Dry Heat (heated air) Sterilizers”.
Outside the United States, the DCS-020 Spore View Culture Set may be used or you may use your local
laboratory for spore testing. Spore strips should be inoculated with B Stearothermophilis and Bacillus
Atrophaeus.
Monitoring can be performed following the procedure below using the DSSH-1 Spore Strip Holder (supplied).
Use of the Spore Strip Holder is recommended in order to keep the biological indicator from moving around
the chamber which may result in false test results.
1) Place the DPS-012 PassPort Monitoring Service strip (supplied) in the slot of the DSSH-1 Spore Strip
Holder. Be sure to have the entire spore strip placed in the slot with only a small piece of the glassine
envelope protruding to allow for easy removal.
2) Place the Spore Strip Holder on top of a full rack (as shown below) in the chamber. Send the strips
for test as indicated on the Passport or EMS Systems or test according to the SporView Culture Set.
For more information on monitoring, please contact Dentronix Customer Service.
3. For customers who wish to test in their office, Dentronix also offers dry indicator strips (DIS100) which can
be used on every cycle or the 370 starter kit (DSK037) for weekly testing.
