soaking them for 10 hours in Glutaraldehyde.
cold sterilization is used to sterilize instruments such as plastics
Even if the instrument is sterilized, as this illness is passed into the blood and sex.
Medical instruments and equipment must be properly sterilized to ensure they are not contaminated. Frequent handwashing by healthcare workers and visitors is necessary
When instruments are sterilized in an autoclave, the temperature must typically be maintained at 121 degrees Celsius (250 degrees Fahrenheit) for a minimum of 15-30 minutes, depending on the load size and type of materials being sterilized. This high temperature, combined with steam under pressure, effectively kills bacteria, viruses, and spores. For certain applications, higher temperatures and longer exposure times may be required. Proper validation of the sterilization process is essential to ensure effectiveness.
Cold sterilization, where the instruments are put in a chemical solution, and it takes around 12 hours for them to become sterilized. Heated sterilization, which is done in an autoclave, under high heat and high pressure. It only takes a few minutes for the instruments to be sterilized.
Instruments such as metal spatulas, forceps, and scalpels can be flame sterilized. Items should be heat-resistant and have smooth surfaces that can be easily sterilized without damage. It's important to exercise caution when flame sterilizing to prevent accidental fires or burns.
As most plastics used in specimen tubes will melt if sterilized with heat the plastic tubes are normally single use
No. Use glass jars that have airtight seals and can be sterilized. Plastic won't ensure your home-made mayonnaise will remain safe.
Sterilized instruments typically have a shelf life of about 6 to 12 months, depending on the method of sterilization used and the storage conditions. Factors such as packaging integrity, environmental conditions, and exposure to contaminants can affect their longevity. It’s essential to regularly monitor and validate the sterility of stored instruments to ensure safety and efficacy. Always refer to specific guidelines and manufacturer recommendations for the best practices.

Glass can be easily sterilized and, thus, very suitable for medical use. Glass can be autoclaved - to render it sterile.
Tools such as scissors, forceps, scalpels, tweezers, and dental instruments can be effectively sterilized in a UV cabinet. UV light is particularly useful for surfaces and objects that are difficult to sterilize through traditional methods like autoclaving.
