Autoclave is one of the most effective means of sterilization. The first example of autoclave is the pressure cookers for cooking (inventive pressure cookers) that were invented in the late seventeenth century. The autoclave was used in the nineteenth century for sterilization in microbiology. The working principle of the autoclave is that the sterilization work is carried out under saturated water vapor under pressure. The sterilization medium contains moisture, so the temperature transfer is faster. The first autoclave has a higher boiling point than 100.ühigh sıtemperatureıklara three ofsterilization techniqueğwas invented on the need for.
Autoclave is a French word. spontaneouslyğmeaningıLatin key with auto from na meaningına clavis sözcüThis device was called autoclave. Because the autoclave is a device that automatically locks to prevent accidental opening of the lid and vapor escaping when the pressure rises. The measurement of microorganisms during sterilization does not result from high pressure, but from protein degradation due to high temperature.
Autoclaves are mainly used in operating theaters and laboratories to destroy germs. In the meantime, canned fruit and vegetable enterprises are widely using autoclaves to remove germs. These foods can only be sterilized in autoclaves and become resistant.
Autoclaves used in the canning industry are grouped as normal autoclaves, pressure-cooled normal autoclaves and high pressure autoclaves according to the pressure values applied during sterilization. Furthermore, autoclaves are divided into groups such as continuous and intermittent autoclaves or fixed and rotary autoclaves according to their working style.
High pressure refrigerated autoclaves are particularly preferred for sterilizing food in large-sized cans, glass containers, canned containers made of aluminum and synthetic materials.
The main approach in autoclave sterilization is to ensure that theının a certain ısıto ensure sufficient contact with water vapor.
Depending on the need for use, autoclaves are manufactured in different types. Autoclaves with sterilization unit larger than 54 liters are subject to EN 285 standards and fall into the larger autoclave class. For example, autoclaves used by dentists fall into the small class of autoclaves and are subject to the TS EN 13060 standard.
All these features show that the autoclave is a pressure vessel and, regardless of the type of autoclave used, it must be manufactured and used in accordance with its rules, as well as regular checks and inspections for safe operation.
Control and Inspection Principles of Autoclaves
Efficient and safe operation of autoclaves must be tested at regular intervals. Test and inspection organizations use chemical indicators and biological tests for this purpose. Chemical indicators measure only steam penetration, but not sterilization. Sterilization efficiency of the autoclave is measured in biological tests.
Due to its pressure characteristics, autoclaves are included in the pressure vessels and installations group and are subject to the Regulation on Health and Safety Conditions in the Use of Work Equipment issued by the Ministry of Labor and Social Security. Pursuant to this regulation, the following standards are used in the regular inspections and inspections of autoclaves:
· TS EN 285 Sterilization - Steam autoclaves - Large autoclaves
· TS EN ISO 11140-1 Sterilization of healthcare equipment - Chemical indicators - Part 1: General properties
In general, control and testing of autoclaves must be carried out in the following cases:
- When production is completed
- Before installation and use
- After a change or major repair
- If not used for at least three months
- Probably once a year regularly
Many test and inspection organizations carry out device controls for autoclaves as well as exposure control and load control. our organization TÜRCERT Technical Control and Certification Inc. provides regular inspection and inspection services for all types of autoclaves. Our organization has a competent manager and employee staff and a strong infrastructure in this field.
