Helix test
The Helix test represents a hollow A-type load, i.e. the load with the most critical characteristics.
The test consists of a 150 mm long PTFE tube with a 2 mm internal diameter.
The Helix test simulates the performance of the unit with respect to the sterilization of hollow loads, in
particular:
-
the efficiency of the preliminary vacuum and the penetration of steam within the cavities
-
the temperature and pressure values of the saturated steam during the sterilization phase
After placing the strip in the capsule, position the tube on the lowest tray inside the sterilization chamber.
At the end of the cycle, take the tube out immediately (with care in that the load is still hot) and verify the
result of the test, referring to the indications given on the package.
