STERIM type 4 steam sterilization chemical tests are a key element in the process of ensuring effective sterilization of beauty tools used in beauty salons. The tests are intended to confirm that the autoclave sterilization process was performed correctly and eliminated all forms of microorganisms.



In a beauty salon, the use of chemical tests is crucial to ensure effective sterilization of the instruments used. The use of sterilization not only translates into the safety of your clients, but also builds their trust in your salon.


Type 4 STERIM steam sterilization chemical tests are characterized by ease of use. All you need to do is place them inside the package with the material to be sterilized and read the result after the designated sterilization time.


The products are adapted to monitor sterilization in class B autoclaves, which use steam, offering the highest effectiveness in eliminating microorganisms.



To provide a comprehensive assessment of the effectiveness of the steam sterilization process, STERIM Type 4 chemical tests are included inside each package containing sterilization materials. This particular step is intended to monitor sterilization conditions directly inside the packages. Once the process is complete, the tests should turn from blue to black. The color change of the indicator should cover the entire surface, clearly indicating that the process was completed successfully. If an irregularity occurs or the required parameters are not met, the chemical tests remain intact, signaling that the process must be repeated.
