It does not contain heavy metals, including lead, and is non-toxic. The test allows easy interpretation of the result thanks to the linear indicator that changes color from blue to black.

Under what conditions is the class 4 chemical test performed?

The test's color change occurs at a temperature of 121 to 134 °C, the time needed for the reaction to occur is 20 - 35 minutes. The indicator should be placed inside the sterilization package, setting the process parameters according to standard settings. If the color does not change, it is necessary to repeat the sterilization process.
