A vertical autoclave is a type of steam sterilizer where the chamber is oriented vertically, resembling a cylinder. Unlike horizontal autoclaves, vertical autoclaves allow materials to be loaded from the top, which saves floor space and is convenient for small-scale operations. They use high-pressure saturated steam (usually 121–134°C) to sterilize instruments, culture media, lab glassware, and other heat-resistant items.
Loading: Items are placed in the vertical chamber, usually in perforated trays or baskets.
Sealing and Pressurization: The lid is locked, and the chamber is pressurized with steam.
Sterilization: High-temperature steam penetrates the items, destroying bacteria, viruses, fungi, and spores.
Exhaust and Drying: Steam is released, and items are allowed to cool before removal.
The Vertical Autoclave – Semi Automatic Double Walled is a robust and efficient sterilization device widely used in laboratories, small hospitals, and research facilities. Its double-walled chamber design provides excellent thermal insulation, reducing heat loss, saving energy, and maintaining consistent sterilization temperatures. Operating in a semi-automatic mode, it allows users to control sterilization time and temperature while ensuring safety through pressure gauges, safety valves, and lid interlocks. The autoclave uses high-pressure saturated steam, typically at 121–134°C, to sterilize instruments, glassware, culture media, and textiles. Its combination of durability, energy efficiency, and reliable sterilization performance makes it ideal for facilities that require frequent but moderate-volume sterilization.
