How long does autoclave steam steriliser take?


In hospitals and medical Settings, steam sterilization is a convenient tool for removing pathogens. Machines called autoclaves direct steam and strong pressure to any medical equipment workers fill them with, such as glassware or petri dishes.


Autoclave steam sterilisers  are capable of killing all types of microorganisms, such as bacteria, viruses, and even spores, that are known to survive at high temperatures and can only be killed at temperatures around 130°C.


The advantage of autoclave steam steriliser is that you have the freedom to control heat and pressure levels to thoroughly disinfect the instrument and ensure that it is free of all harmful microorganisms, especially those that cannot be killed by ordinary methods.


The use of autoclave steam steriliser can be used in a variety of industries requiring equipment sterilization. Professionals who use the devices include doctors, nurses, surgeons, beauticians and dentists. In order to achieve complete sterilization, the use of autoclave is necessary.


The lower the sterilization temperature is, the longer the sterilization time is needed; The higher the sterilization temperature is, the shorter the sterilization time is needed. The time of pressure steam sterilization shall be counted from the time when the sterilization temperature is reached in the sterilizer cabinet until the sterilization is completed.


How long does autoclave take?


Total time includes:

1. Heat penetration time is the time required from reaching sterilization temperature in the cabinet to reaching sterilization temperature in the center of the sterilized articles. The length of time depends on the nature of the item, the size of the package, the location and the extent to which the air in the pressure cooker is emptied and the type of sterilizer.


2. Maintenance time is the time required to kill microorganisms, generally expressed by the time required to kill thermophilus adipose bacillus. 30 minutes at 115 ° C, 12 minutes at 121 ° C and 2 minutes at 132 ° C.


3, the safety time is generally half of the maintenance time, its long and short vision disinfection items. The sterilization of metal equipment with easy heat conduction does not need safe time. Depending on the composition and volume of the load, the cycle time may need to be increased.


How long will the item remain sterile?


While autoclaves can kill any type of microbe, maintenance is an important factor to keep in mind.

Maintenance will ensure that your newly autoclaved instruments are not re-contaminated with harmful and infectious materials.

After you autoclave your instruments, it is important to ensure that they are properly stored and safeguarded.

When packing, ensure that the package is free from any structural defects such as holes, scratches or openings, as this can make the instrument vulnerable to contamination.

It is also important to pay attention to the expiry date of the package. Some packages will indicate when they must be replaced and how long they will last.

Typically, they last a year before they can be changed again.


It is important to maintain optimal storage conditions so that your fresh autoclave instruments do not become contaminated again. However, it is also important to pay attention to transport conditions and processing frequency. Ensure that the instrument environment, once included, does not endanger the hygiene of the instrument. By taking care of the instrument after autoclaving, you can ensure that no harmful microorganisms can take over.


Autoclaves kill all types of pathogens, including viruses. This has become particularly acute as the world grapples with the COVID-19 pandemic. Killing viruses is important in some applications where disinfecting medical tools and PPE before they are discarded.


An autoclave steam sterilizer is used to sterilize surgical equipment, laboratory instruments, pharmaceutical items, and other materials. Autoclave steam sterilizer is the preferred method, steam sterilizer equipment may be chosen, for example YG-0.6 Pulse Vacuum Steam Sterilizer
