How do you use an autoclave?

A autoclave is a device used to sterilize materials by steam under pressure. It is often used in the medical and pharmaceutical industries, as well as in laboratories and breweries. It is important to know how to use an autoclave correctly to ensure that materials are sterilized effectively and to avoid safety issues.

Step 0: Cleaning

Before you can sterilize, it is important that the instruments are clean of dirt. An autoclave sterilizes but does not clean the dirt from the instruments. However, you can use an ultrasonic cleaner for this purpose. 

Step 1: Preparation

Before using the autoclave, make sure it is filled with water to the proper level and that the door is securely closed. Make sure the materials you are going to sterilize are clean and dry, and pack them in autoclave bags or in containers suitable for use in an autoclave.

Step 2: Sterilization

Turn on the autoclave and select the desired sterilization time and temperature. Wait for the autoclave to reach the desired pressure and temperature before starting sterilization. Keep in mind that the sterilization time depends on the size and quantity of the materials you want to sterilize.

Step 3: Cooling down

After sterilization, the autoclave must be cooled before the door can be opened. This is done automatically in modern autoclaves. This is important to do to reduce pressure from the sterilization chamber and to prevent accidents from happening.

Step 4: Storage

Ensure that the sterilized materials are kept in a clean and dry environment until they are used.

Keep in mind that each autoclave is different, so always consult the autoclave's manual for specific instructions. It is also important to perform regular maintenance and have the unit checked by a qualified technician.
