STEAM PLUS supplements, 100 pieces, Tecno-Gaz

The STEAMPlus™ chemical indicator is a product with advanced technology that guarantees the correct monitoring of saturated steam sterilization parameters in both 134°C and 121°C cycles.
Very practical and precise, STEAMPlus™ does not require interpretation of the results, as the sterilization process is controlled simply by reading the progress of the migrating bar.
This product has been certified in accordance with the Technical Standard ISO 11140-1 as a Class 5 indicator, as it is able to guarantee performance comparable to that of a biological indicator (Geobacillus Stearothermophilus).

STEAMPlus™ is designed to integrate the three critical parameters of steam sterilization: time, temperature, and the presence of saturated steam.
The results are read through a practical window divided into a double reading area: if the supplement has undergone a correct sterilization cycle , the ink advances within the reading window until it reaches the blue "SAFE" zone.
The arrival position of the migrating bar within the blue "SAFE" zone is irrelevant.
If the dark bar does not reach the blue "SAFE" zone, the sterilization conditions have not been met.

The STEAMPlus™ integrated indicator consists of the following components:
1. The base is made of a thin aluminum foil with a thickness of 0.07 mm. The aluminum foil acts as a barrier to the penetration of steam during the sterilization cycle.
2. On the underside of the base, there is a capsule containing an ink that is sensitive to temperature and the presence of saturated vapor.
3. The ink contained in the capsule is designed to melt at specific temperatures and only in the presence of saturated steam.
4. The inner part of the cartridge consists of a strip of paper that indicates the ink's progress (migrating bar).
5. The upper part consists of a polymeric film coupled to a paper support shaped like a reading window.

The steam penetrates exclusively through the top part of the adapter.
When the temperature reaches the required level, it causes the ink contained in the capsule to melt.
The ink, thus liquefied, is absorbed by the internal paper component and, as the exposure time passes, it progressively saturates the structure, thus creating an advance by migration within the reading window.
The rate of ink liquefaction depends on both the penetration of vapor and the relative temperature.
The combination of these parameters, associated with the holding time, follows the behavior of a biological indicator consisting of Geobacillus Stearothermophilus spores, while guaranteeing an additional margin of safety.
