Sterilization Fractional

Fractional sterilization is a sterilization method that involves sequential exposure of objects to high temperatures and ultraviolet radiation. This method was developed in the 1950s and has since been widely used in medicine, the food industry and other industries.

Fractional sterilization includes several stages:

1. Pre-treatment: The item is exposed to high temperature (eg 121°C for 30 minutes) to kill all microorganisms.
2. UV treatment: The item is placed in a chamber where it is exposed to ultraviolet light for a certain amount of time (usually 60 seconds).
3. Final treatment: After ultraviolet irradiation, the item is again exposed to high temperature (eg 82°C for several minutes) to finally kill microorganisms.

The benefits of fractional sterilization include:

– high efficiency: the method allows you to destroy all microorganisms on an object;
– versatility: the method can be used to sterilize various items, including medical instruments, utensils, equipment, etc.;
– convenience: the method does not require the use of special tools or equipment, which makes it simple and convenient to use.

However, fractional sterilization also has some disadvantages:

– duration of the process: the sterilization process can take up to several hours;
– high cost: the use of ultraviolet radiation can be expensive;
– Possibility of item damage: Some materials may be damaged when exposed to high temperatures or ultraviolet radiation.

Overall, fractional sterilization is an effective and versatile sterilization method that is widely used in various industries. However, before using this method, it is necessary to take into account its disadvantages and select the optimal conditions for each specific case.
