What materials can be sterilized using dry heat?
Materials that can be sterilized using dry heat
| Material | Maximum Temperature |
|---|---|
| Celluose acetate (nonload) | Up to 120°C |
| Glass | >190°C |
| Ethylene chlorotrifluoroethylene copolymer | Up to 150°C |
| Ethylene tetrafluoroethylene | Up to 150°C |
How do you sterilize with dry heat?
Dry heat sterilization typically involves exposing an item to a temperature of 170°C under normal air pressure for around an hour. That time period ensures that even the most resistant spores get killed off via oxidation of their cellular components.
Which equipment is used for sterilization?
Instrument list
| Instrument | Uses |
|---|---|
| Hot air oven | used in sterilizing instruments for various aseptic procedures, specially if that can not be autoclaved like powders |
| Koch’s or Arnold’s steam sterilizer | used for steam sterilization |
| A pressure cooker | used as a portable autoclave |
What are two types of dry heat sterilization?
There are two types of dry-heat sterilizers: the static-air type and the forced-air type. The static-air type is referred to as the oven-type sterilizer as heating coils in the bottom of the unit cause the hot air to rise inside the chamber via gravity convection.
What is the simplest method of dry heat sterilization?
Sterilizing by dry heat is accomplished by conduction….Principle of Dry heat sterilization using HOT AIR OVEN
- 170°C (340°F) for 30 minutes,
- 160°C (320°F) for 60 minutes, and.
- 150°C (300°F) for 150 minutes or longer depending up the volume.
What is dry heat sterilization and its application?
Dry heat sterilization (killing or removal of all microorganisms, including bacterial spores) technique requires a longer exposure time (1.5 to 3 hours) and higher temperatures than moist heat sterilization. Various available methods of dry heat sterilization are; hot air oven, incineration, flaming (wire loop), etc.

What are the types of sterilization?
There are several different types of sterilization used for these purposes. Most commonly, heat is used to sterilize these products to achieve a SAL of 10-6. There are two distinctive types of heat-based sterilization: Moist Heat Sterilization and Dry Heat Sterilization.
What is the definition of dry heat?
Dry heat sterilization of an article is one of the earliest forms of sterilization practiced. Dry heat, as the name indicates, utilizes hot air that is either free from water vapor, or has very little of it, and where this moisture plays a minimal or no role in the process of sterilization.
What is moist heat sterilization?
Moist heat sterilization is a technique that uses heated water and superheated steam to disinfect contaminated materials, such as culture media, surgical instruments, glassware and other non-thermally sensitive items.
