Disinfection of materials and tools is an important component of day-to-day work in the research and medical fields. Hot air sterilization is one method of effectively killing microbes of all kinds, especially bacteria, viruses and molds on heat-resistant materials. Contamination control during the incubation of cell cultures in a CO2 incubator is of the greatest importance. To guarantee sterile conditions, our unit offers an auto-sterilization program, which sterilizes the empty chamber with air heated to 180 °C and can be used to create an ideal growth environment for cell or tissue samples. Our hot air sterilization program is based on DIN 58947 and ensures that the incubation chamber is disinfected at a temperature of at least 180 degrees Celsius. Our Anti-Plenum Design series of products is exceptionally well suited to practical application; the CO2 incubator stands out because of its simple, convenient operation in medical practices and research facilities.

1. What is the principle of hot air sterilizer?
A hot air oven is a type of dry heat sterilization. Dry heat sterilization is used on equipment that cannot be wet and on material that will not melt, catch fire, or change form when exposed to high temperatures. Moist heat sterilization uses water to boil items or steam them to sterilize and doesn't take as long as dry heat sterilization. Examples of items that aren't sterilized in a hot air oven are surgical dressings, rubber items, or plastic material.
Items that are sterilized in a hot air oven include:
· Glassware (like petri dishes, flasks, pipettes, and test tubes)
· Powders (like starch, zinc oxide, and sulfadiazine)
· Materials that contain oils
· Metal equipment (like scalpels, scissors, and blades)
Hot air ovens use extremely high temperatures over several hours to destroy microorganisms and bacterial spores. The ovens use conduction to sterilize items by heating the outside surfaces of the item, which then absorbs the heat and moves it towards the center of the item.
The commonly-used temperatures and time that hot air ovens need to sterilize materials is 170 degrees Celsius for 30 minutes, 160 degrees Celsius for 60 minutes, and 150 degrees Celsius for 150 minutes.
Dry heat sterilization methods are of two types: the static air type and the forced air type.
The static air type
This kind of sterilization is commonly referred to as the oven type sterilizer. Here, the heating coils which are found at the bottommost part of the unit initiates the rising of the hot air inside the chamber through gravity convection. This dry heat sterilizer is, however, relatively slow in heating and a consequential longer time for sterilization of the custom tray.
Forced air type
Here, the sterilizer has a motor driven blower that circulates hot air throughout the chamber. The hot air is blown at a high velocity which makes it possible to transmit the energy faster form the air to the instrument. Forced air type dry heat sterilization method, unlike its static counterpart, ensures that the hot air is spread uniformly throughout the chamber thus making it more ideal.
3. Factors essential to achieving sterilization
For sterilization to be attained, there are factors that have to be considered some of which are listed below.
Temperature
Heat works to denature proteins in bacteria on the custom tray. Essentially, denaturing involves disrupting the hydrogen bonds and thus leading to the death of the bacteria. When the temperature of the autoclave is tuned higher, it reduces the time it would take to sterilize the custom tray. In the autoclave, the temperature of the saturated steam is in direct proportion to pressure.
Time
The fundamental goal of sterilization is to kill all organisms. However, all organisms do not die at the same time. This brings in the time factor in during the process of sterilization. Basically, you have to maintain sterilization conditions inside the autoclave chamber for a time sufficient enough to kill the organisms on the custom tray that take a relatively longer time to die. Otherwise, you'd not be killing all the organisms on the equipment.
Air removal
Air insulates the surface of the custom tray being sterilized hence preventing it from effectively being sterilized. So to ensure you have done the process optimally, you must see to it that you remove the air from the surface of the custom tray. Failure to remove it, a contamination spot can form on the surface which can be turn out to be dangerous for the patient who would go through the procedure. There are two methods you can use to remove air from the surface of the custom tray: gravity displacement autoclaves and dynamic air removal method.
