Horizontal Steam Sterilizers

How Horizontal Steam Sterilizers Grew in Last Decade

Sterilization is an important process in every laboratory. Hospitals and laboratory deal with virus and bacteria on a regular basis. So they constantly need to check all the instruments or equipment they are using are completely safe and germs free. Manually, it is not possible so sterilizers came into existence. A device that is used to kill the germs from the medical instruments with the help of steam. Steam sterilization is inexpensive and nontoxic and rapidly heats. We are discussing some aspects of the horizontal steam sterilizer India and how this device has become the most vital part medical industry.

Why it is called Steam Sterilizer?

A sterilizer is a general term for any device that can sterilize whereas an autoclave sterilizer is a specific device that sterilizes equipment. We often consider autoclave and sterilizer as one thing. There is a slight difference between both of them. Sterilizers can be of various types but autoclaves are especially used as the steam sterilizer. Steam is a prime element in horizontal steam sterilizers. To kill the bacteria and germs, we must need high temperature so that protein in the cell can break and coagulate. Steam is a very efficient medium for transferring the heat, so that is can kill microbes. Steam sterilization and autoclave are closely related to each other. In fact, they are often used interchangeably. An autoclave is generally used in the laboratory while Sterilizer is more commonly used in hospitals. The autoclave is a device that is used to kill germs and bacteria using steam heat.

How Autoclaves or Horizontal Steam Sterilization Came Into Existence?

The autoclave was founded in 1879 by Charles Chamberland but the concept of sterilization was available in earlier times. In initial times, doctor mostly used traditional methods for sterilization but those methods were not that much reliable and effective, so nowadays autoclaves sterilizers became the essential part of every clinic and hospital.

Working process of Horizontal Steam Sterilizer:

We know that steam sterilizer comes in different sizes but all kind of steam sterilizer works on the same principle. The main door of sterilizer is locked to form a sealed chamber and all air within the chamber is replaced by steam. After that steam is pressurized to reach the expected sterilization temperature and time, before exhausting the steam and allowing the devices that are being sterilized to be removed.

The whole process happens in 3 part:

  1. Purge Phase
  2. Sterilization Phase
  3. Exhaust phase

The main components of the horizontal steam sterilizer are:

  • Chamber
  • Control system
  • Thermostatic Trap
  • Safety valve
  • Vacuum system
  • Steam generator

Why do we need for this device?

Chamber of steam sterilizer sterilizes medical or laboratory instruments by heating them above boiling point. Most clinics use small steam sterilizers similar to microwave ovens. Hospitals use large autoclaves, also called horizontal steam sterilizer. They are used in the operating room and emergency wards. During operation or any surgical process, doctors ensure all the instrument that is used in operation are germs free to prevent any possible infection in the patient.


The bottom line is whether you are using horizontal steam sterilizers India to sterilize laboratory equipment. Also, it is very important you must have a proper understanding of how the sterilization process works and why it is used and how it changing.
