What are the Different Types of Autoclaves?
Introduction
Autoclaves are sterilization devices used in medical and laboratory settings to eliminate bacteria, viruses, and other pathogens from medical equipment. However, not all autoclaves are the same.
Understanding the differences between autoclaves types can ensure effective sterilization, compliance with health regulations, and infection control. In his article, we’ll explore the different types of autoclaves so you can choose the best option for your practice.
Capacity
The amount of instruments your facility needs to sterilize, as well as the amount of available space your practice has, can help determine which autoclave size you need.
Small Capacity
A small capacity autoclave is a compact sterilization unit designed for low-volume sterilization needs. These autoclaves have a smaller chamber size of less than 40 liters, making them ideal for clinics and private practices. Small capacity autoclaves often feature rapid cycle times and tabletop designs.
Medium Capacity
Medium capacity autoclaves generally range from 40–200 liters in capacity. Many medium-sized autoclaves feature pre-vacuum sterilization, which removes air from the chamber for thorough sterilization of instruments.
Large Capacity
Large capacity autoclaves have a capacity of 200 liters or more designed pharmaceutical labs and industrial sterilization applications. With high-capacity chambers, large autoclaves can accommodate sterilization of linens, large equipment and more.
Sterilizer Class
The 3 main autoclave classes are: Class N, Class S and Class B, which all have various sterilization methods.
Class N
N-Class autoclaves are non-vacuum sterilizers designed for solid, unwrapped instruments as well as other simple sterilization needs. These autoclaves use gravity displacement to push air out of the chamber with steam, making them suitable for basic medical tools.
Class S
S-Class autoclaves are sterilizers that offer more versatility than N-Class models. These autoclaves use limited vacuum technology to remove some air from the chamber. S-Class autoclaves are often used when a wide range of instruments need sterilization.
Class B
B-Class autoclaves are high-performance vacuum sterilizers that meet the highest sterilization standards. They use a pre-vacuum and post-vacuum system to completely remove air from the chamber, allowing for the effective sterilization of complex instruments.
Closing
Understanding the differences between Class N, Class S, and Class B autoclaves, as well as different size capacities, is essential for selecting the right autoclave.
Class N autoclaves are ideal for basic instruments, while Class S models provide more flexibility. For the most comprehensive sterilization, Class B autoclaves offer vacuum technology to handle wrapped, complex, and high-risk instruments. To view our full catalog of autoclaves, click here.
