Product Information


 Class 2 - Indicators for use in Specific Test

  • such as an Air Removal Test / Helix Test ( either Bowie-Dick-Type test for use when processing porous loads of cotton rolls,  gauze post extraction packs, cotton wool and the like or a Process Challenge Device (PCD) to be used for general dental instruments,  particularly hollow instruments) which measures the effectiveness of air removal and even penetration of steam in a pre-vacuum sterilizer.
  • In using a pre-vacuum autoclave, a Class 2 Air Removal Test must be run each day (the very first empty cycle of the morning) to test the ability of the vacuum pump system to remove air adequately.*
