Laboratory Autoclaves are available as the physical techniques for disinfection and sterilization. They work with a combination of steam, pressure and time. They are functional with the high temperature and pressure and are made to kill microorganisms as well as spores.Also, these are utilized to decontaminate the sterilize mediaand biological wastes. Laboratory Autoclaves make use of the pressurized steam fordestroying the micro-organisms. Usage of these units is required in the microbiology laboratory for the preparation ofreagents and culture media. They are also useful for purifying biohazardous waste materials.They are functional as the advanced physical methods that perform disinfection and sterilization.
