Significance of autoclaves in medical industry!

Autoclaves are an integral part of medical industry and scientific laboratories, used for sterilizing instruments and tools with the help of moist heat. The sterilization procedure is carried out with the help of pressurized saturated steam at temperature of approximately 250 Fahrenheit. The main purpose of autoclaves is to kill bacteria and microorganisms that may accumulate on surgical tools and equipments.

When compared with other methods of sterilization, the sterilization using moist heat is one of the best ways to clean equipment used in medical industry and other laboratories. This sterilization requires low temperatures and consumes very less amount of time as compared to other techniques to get same results. This type of sterilization works the best for materials that cannot bear high temperatures.

There are many companies that manufacture different types of laboratory instruments. There are numerous types of autoclaves that are available in the market. They are classified into different types, depending upon the technique that they use for removing air from sterilization chamber in the beginning of this procedure.

Also, there are botany models, used in school and college laboratories. The main purpose of these models is to make students familiar with structure of plants. Dicot flower model, leaf structure model and stem model are some of the different types of models that you can easily get through manufacturers manufacturing other laboratory tools and equipment.

Mentioned below are some of the types of autoclaves that are commonly used
for sterilizing medical and scientific tools and equipment.

1. Downward displacement

These types of autoclaves are also known as gravity displacement units. They are named as downward displacement units due to their method of air removal from sterilization chambers. A heating element is submerged in water and produces steam, when heated. Steam is lighter than air, which forcers air in the sterilization chamber to go downwards and finally moves out through a drain hole. Once, the temperature becomes relevant in chamber, the sterilization process begins by closing drainage hole automatically.

2. Positive pressure displacement

The positive pressure displacement units are better than downward displacement units. There is a positive improvement in design of these units, when compared with downward displacement units.  These units have separate chambers for different purposes. Steam is produced in a separate chamber till adequate amount of steam is generated in the chamber.

3. Negative pressure displacement

It is one of the best types of autoclave sterilizer units that are available in the market. A vacuum pump is available in these units to remove air when the door of the chamber is closed. The steam is then released into sterilization chamber.

Therefore, depending upon your needs and requirements, make your purchase for the best option.
