Autoclaved Meaning: Definition and Examples
🏗️
autoclaved
[ɔːtəˈkleɪvd ]
Definition
manufacturing process
Autoclaved refers to materials or products that have been subjected to the process of autoclaving, which is a method of sterilization using high pressure and temperature, often applied in construction and medical fields. This process can ensure durability and enhance the characteristics of the material treated.
Synonyms
processed, sterilized, treated.
Examples of usage
- Autoclaved aerated concrete blocks are lightweight and provide good insulation.
- The surgical instruments were autoclaved to ensure they were sterile before the operation.
- Autoclaved clay bricks are used in eco-friendly building construction.
Interesting Facts
Science
- Autoclaving is a critical method in microbiology for sterilizing instruments and media to eliminate all forms of life, including bacteria and viruses.
- The process typically occurs at around 121 degrees Celsius (250 degrees Fahrenheit) at 15 psi, allowing for effective sterilization in about 15-30 minutes.
Medicine
- In hospitals, surgical instruments are autoclaved to ensure they are completely free of pathogens before being used on patients.
- Autoclaving is a standard procedure in laboratories, particularly in any field involving biohazardous materials.
History
- The concept of using steam for sterilization was first utilized in the mid-19th century, with Louis Pasteur advocating for heat to kill germs.
- The first practical autoclave was designed by Charles Chamberland in 1884, aiding the advancement of sterilization technology.
Environmental Impact
- Unlike incineration, autoclaving is considered environmentally friendly as it significantly reduces waste volume while safely destroying harmful pathogens.
- Many medical facilities are now employing autoclaving as part of their waste management strategies to minimize environmental impact.
Origin of 'autoclaved'
Main points about word origin
- The term 'autoclave' comes from the French word 'autoclave', meaning 'self-locking', emphasizing its sealed nature during the process.
- The prefix 'auto-' signifies that the process operates automatically once started, while 'clave' relates to ‘to close’ in Latin.
The term 'autoclaved' originates from the combination of 'auto-' meaning self and 'clave' which comes from the Latin 'clavis', meaning key. The term began to be used in the early 20th century when industrial processes for creating sterilized environments were being developed, particularly in the medical and construction industries. The autoclave itself serves as a key instrument in these processes, allowing for high-pressure steam and heat to combine, effectively eliminating microbes and ensuring structural integrity. Over time, various materials has been put through the autoclaving process, leading to advancements in construction materials and medical sterilization techniques.
