Vertical Gravity Displacement Autoclave

At Harsha Engineers, we manufacture high-quality Vertical Gravity Displacement Autoclaves designed for efficient sterilization in laboratories, hospitals, and research facilities. Built with a vertical cylindrical chamber, these autoclaves save floor space while ensuring uniform sterilization. They operate on the principle of gravity displacement, where steam replaces the air inside the chamber, providing a safe and reliable sterilization process for laboratory glassware, culture media, dressings, and surgical instruments.

Our vertical autoclaves are engineered with precision to meet industrial and medical standards, ensuring durability and consistent performance. They are available in a wide range of capacities and can be customized with stainless steel construction, safety features, and user-friendly controls. With their robust design, cost-effectiveness, and easy operation, Harsha Engineers Vertical Gravity Displacement Autoclaves are trusted solutions for industries that demand reliable and long-lasting sterilization equipment.

This autoclave operates on the gravity displacement principle, where steam enters the vertical chamber and pushes the heavier air downward and out through a drain. Once the air is displaced, the chamber fills with steam, ensuring direct contact with the load. The sterilization cycle typically involves:

Air Removal – Steam enters and displaces air from the chamber.
Sterilization Phase – The chamber is maintained at the desired pressure and temperature (usually 121°C at 15 psi or as per requirement).
Exhaust & Cooling – Steam is released, the pressure drops, and the load is cooled before being removed.

This process ensures uniform sterilization without air entrapment, making it highly reliable for routine sterilization tasks.
