The principle of the use of autoclaves

Structure principle of the use of autoclaves

Autoclaves pressure Chamber is a practice often used to make the process of sterilization instruments, chemicals,... in industry, health, -laboratory, industrial chemical ... under pressure and high temperature. Some autoclaves are used to sterilize equipment by putting them into the pot under pressure than water saturation in 121 degrees c (This is also principle of autoclaves currently), in about 15 to 20 minutes, Depending on the size and quantity of materials. Find out more on the sterilization method of instruments.

Autoclaves was invented in 1879 by Charles Chamberland.

Uses of autoclaves

Autoclave sterilizers are often widely used in microbiology, pharmaceutical products, health, veterinary medicine, Science of germs, built ... We have many types and sizes, Depending on the sterilization applications.

The sterilized material including: laboratory glass, laboratory instruments, the equipment, waste, micro solvent.

one the use of autoclaves recent notable and increasingly common is money waste as: medical waste, laboratory waste, infectious substances. Pasteurization in this group the source material like a pressure cooker to disable the underlying infection causing substances under high pressure and temperature as: bacteria, germs, pathogenic bacteria cultured in the process ...

Sterilizing autoclaves are also used extensively to handle composite during rubber vulcanization. Temperature and high pressure allow the protein the best physical properties. In the aerospace industry and mining. And this is usually the large type autoclaves up to : long 15 m and higher 3 m.

Types of autoclaves used to grow crystals under high temperature and pressure. Synthetic quartz crystal used in electronic industry.

The use of autoclaves in medical field

Medical autoclaves commonly use saturated steam to sterilize equipment and laboratory instruments aimed at eliminating all bacteria, the virus, fungi and spores. However there are a number of types such as the Prion, the disease Creutzfeldt-Jakob can not be destroyed by cleaning the normal temperature at ripening 134 degrees C in 3 minutes or 121 degrees C in 15 minutes.

Autoclaves commonly used in medical institutions , Lab and elsewhere to ensure sterile instruments and chemicals can reuse. Today, many items are sterile production only used 1 times and cannot be re-used as: Needles, clamp, Kim poultry, scalpels ... So the autoclave is currently used in many developing countries to ensure the economics. Autoclaves using solar energy is also a new trend in the future.

Made popular autoclaves

Autoclaves There are usually several types as follows: Vertical autoclaves, Horizontal, automatic and semi-automatic, mechanics and electronics, autoclave vacuum drying integration ... with many different sterilization Chamber volume depending on the needs of users.

Construct autoclaves include the following parts:

– Sterilization Chamber usually made of stainless steel 304 or 316 longevity protein high in moist environment, pressure and high temperature. The shape is generally the cylinder according to the principle of the big pressure cylinder.

– Pressure gas system: mission control the pressure and temperature sterilization. A structure made of copper tubes in combination with electromagnetic valve.

– The safety system is the heat sensor, pressure sensor, door sensor, water level sensor in the heat Chamber. .. depending on the manufacturer and model that is also different safety levels. The line of autoclaves for high safety as: ALP-Japan, Hirayama-Japan, Tomy-Japan, Study-Taiwan…

– Heating parts : Usually made of coated incandescent by a layer of insulation and heat. Outer layer made of chromium plated brass, Stainless or ... This is the frequent contact with water and chemicals so frequently daily hygiene to avoid damage. Stick the thermal protection through thermal sensor and sensor water level of sterilized sad.

– Electrical system including: the way the source motherboard, controls, show. The task of the connection between the parts that make up the correct rhythmic functioning operating Process.

Above is the structural principles and uses of autoclaves are commonly used at present.
