Contains 1 x TST Helix 250 x TST Strips For testing air removal/steam penetration of small type B sterilisers ONLY.
The TST Helix has a limited life when the 250 indicators have been used the device MUST be replaced
This test validates the vacuum and steam penetration of the cycle and is only required for vacuum sterilisers (Type S & Type B). It is not performed on a non-vacuum Type N steriliser.
The test is performed to ensure that the steam penetration of the cycle is efficient when processing wrapped or hollow loads.
This is achieved by validating that air and/or non-condensable gases in the chamber that impair sterilisation have been removed sufficiently by the vacuum stage of the cycle.
With air and/or non-condensable gases removed, the steam can then penetrate the entire load rapidly and evenly
