Class B Pre-post Vacuum Autoclaves are highly reliable and effective medical autoclaves. They offer better performance than Class S chambers by removing more air from difficult-to-sterilize loads, including capillary and porous instruments. These autoclaves meet current sterilization standards, such as ANSI/AAMI ST55, ensuring compliance with industry regulations. Class B autoclaves are the preferred choice for clinics and healthcare facilities due to their ability to provide thorough sterilization.
