The use of high-pressure saturated steam to sterilize laboratory equipment and supplies is known as autoclaving. The decision between autoclavable and non-autoclavable labware is determined by the materials used and the specific needs of the experiment or process.
Autoclavable labware is laboratory equipment and containers intended to survive the extreme temperatures, pressure, and steam conditions of an autoclave. An autoclave is a device that uses high-pressure saturated steam to sterilize equipment and supplies. In laboratories, autoclaving is a typical process for ensuring that things are free of germs such as bacteria, viruses, and spores. Autoclavable labware is typically composed of materials that are resistant to the autoclaving process. The autoclaving method involves exposing the labware to steam at a temperature of roughly 121 degrees Celsius (250 degrees Fahrenheit) for a set amount of time, usually between 15 and 30 minutes. This successfully eliminates bacteria and spores, allowing the labware to be used in sterile laboratory settings. Autoclavable labware has the advantage of being able to be sterilized and reused several times, making it more cost-effective in the long run. This is particularly significant in research and medical contexts, where sterility is critical for experimentation, cell culture, and other applications.
Non-autoclavable laboratory equipment or containers are those that cannot survive the high heat and pressures employed in the autoclaving procedure. Autoclaving is a typical procedure for sterilizing laboratory equipment and supplies by exposing them to high-pressure saturated steam. Autoclavable materials can withstand these extreme temperatures without being harmed, ensuring effective sterilization. Non-autoclavable labware, on the other hand, is built from materials that would be damaged by the heat and pressure of autoclaving. Certain types of plastics with low melting points, rubber, or materials that may distort or break in an autoclave may fall into this category. Items classified as non-autoclavable should not be autoclaved because it can cause damage, distortion, or contamination. For non-autoclavable labware, other sterilization procedures such as chemical disinfection, UV irradiation, or filtration may be required. To guarantee correct usage and maintenance of laboratory equipment, whether autoclavable or not, it is critical to follow manufacturer specifications and standards. Inappropriate use of non-autoclavable labware may affect experimental results, introduce contaminants, or even destroy the equipment.
