Types Of Autoclaves And Safety Measures

November 3, 2021


They are used exclusively for the sterilization of solid load, that is, solid products such as: forceps, needle holders. Sterilized instruments cannot be transported or stored, they must be instruments for immediate use. They do not allow the sterilization of textile materials, porous loads, hollow bodies or bagged products, since the characteristics of the cycle do not allow specific tests to be passed from the physical point of view. Another weakness of these devices is that proper steam penetration is not guaranteed.

CLASS  Main Characteristics  :

  • They are the lowest cost equipment since their quality of materials is lower, which does not allow to rise to the necessary temperatures and pressure required to obtain the best sterilization results. Another disadvantage is, Their security measures are low, they can put the user and their work area at risk.
  • They are mostly manual process
  • Son analogicas
  • Small sizes
  • Gravitational cycle.
  • Intended for immediate use or storage for non-sterile application (eg to prevent cross infection).
  • They do not have a registration system that allows documentary verification of the result of the cycle.


They sterilize any type of load that a large sterilizer can process: porous materials, bagged materials, textiles, and hollow bodies such as instruments, turbines, and cannulas. Those sterilizers already have a specific cycle to test steam penetration. For all wrapped or unwrapped products. Solid, porous and type A hollow charge.

CLASS B  Main Characteristics  :

  • They meet the highest demands in terms of safety and performance.
  • They have gravity and vacuum cycles, including cycles for prions.
  • They have penetration and vacuum test cycles.
  • They have data processors and mandatory registration of the same.
  • They have a larger volume for cargo.
  • High quality
  • Very high pressure


They are sterilizers that have cycles defined by the manufacturer, with programs for packaged solid material, porous material (material that can absorb fluids, examples of porous loading would be surgical gowns and gauze) as well as devices with lumens of determined diameters and lengths. They are teams that usually incorporate a vacuum pump

S CLASS  Main Features  :

  • They meet the requirements in terms of safety and operation.
  • They have gravitational and vacuum cycles
  • Improved quality
  • They have a larger volume for cargo.
  • High pressure

Types of load in an autoclave

The types of loads that can be autoclaved for sterilization are as follows:

  • Solid load: They are non-porous items, without grooves or fissures or other characteristics that may hinder the penetration of steam into the material, examples of solid load are tweezers, scale cleaners, needle holders, mirror.
  • Porous filler: material that can absorb fluids, examples of porous filler would be surgical gowns and gauze.
  • Type A hollow charge: length / diameter> 5mm, example of type A hollow charge would be a turbine
  • Type B Hollow Charge: length / diameter <5mm, an example of a Type B Hollow Charge would be a surgical cannula

Born and raised in Brussels in an English family, I have always lived in a multicultural environment. After several work experiences in marketing and communication, I came to Smart Water Magazine, which I describe as the most exciting challenge of my career.
I am a person with great restlessness and curiosity to learn, discover what I do not know, as well as reinvent myself daily, someone who is curious about life and wants to know. I enjoy sharing knowledge.
This is my personal project but I also collaborate in other blogs, it is the case, the most important web on water currently exists in the US, if you are interested you can read my articles here.
