We all know that UV rays, i.e. the ultraviolet light spectrum, can be very harmful to our skin and eyes.

But everything contains its opposite and in fact UV rays play a fundamental role in our health thanks to their sterilizing capacity.

The UV sterilization chamber is the most used tool for this purpose and has been used for more than a century to ensure hygiene in the medical and healthcare fields.

Let's find out together.

History of the UV Sterilization Chamber


The discovery of sterilization itself dates back to the nineteenth century and we have addressed it here, talking about other possible methods tested in those years.

As far as sterilization using UV rays is concerned, however, we owe the discovery to the English biologist Arthur Downes and the German chemist Thomas P. Blunt who developed it in 1878.

The technology was perfected over the decades and the first UV sterilization chambers were introduced in the 1920s.

Since then, UV sterilization chambers have been progressively perfected but the principle has remained the same and they are still among the most used sterilization tools today.

What is a UV Sterilization Chamber for?


As we have anticipated, the Sterilization Chamber finds its main use in the medical and health sector.

Sterilization chambers are therefore essential in all environments where hygiene is essential: i.e. hospitals, laboratories, dental surgeries but also beauty salons.

Their main task is in fact to sterilize work tools - whether they are medical or aesthetic - which come into direct contact with the human body.

But according to which principles does the UV sterilization chamber work?

How does a UV Sterilization Chamber work?


The UV sterilization chamber makes use of the particular properties of UV rays, i.e. that part of the spectrum of light (visible and non-visible) defined as ultraviolet.

In fact, this light has sufficient energy to destroy the DNA of microorganisms and pathogens that can be found on work tools that will come into direct contact with the human body.

There are various models of UV sterilization chambers which differ in size and power. The layout of the lighting system inside the chamber is fundamental, which will determine the quality and efficiency of the sterilization process.

In the sterilization process, the instruments to be sterilized are first conditioned and then placed inside the chamber for a variable time interval depending on the power of the medium and the sterilization needs.

However, these procedures are outlined in international standards.

International Standards for UV Sterilization


The UV sterilization procedures in the sterilization chamber are regulated by a series of internationally recognized standards, all issued by ISO, the most important international standardization body.

The main standards to be followed for UV sterilization in the medical field are ISO 11137, ISO 17665 and ISO 11135.


The FDM Climatic Chamber for UV Sterilization

Climatic chambers are the ideal tool for the tests we have mentioned, as they are capable of both carrying out the conditioning process and the actual sterilization.

The FDM climatic chambers can be equipped with a UV ray lighting system capable of efficiently and quickly sterilizing all work tools in the medical, health and aesthetic fields.
