Purchasing any equipment from Roch Mechatronics ensures that you are receiving the best product from the market.

We also provide equipment according to your need and requirement. We are one of the highest quality autoclave manufacturer and most advanced Autoclave Manufacturer in the industry.

All of the autoclave units we offer have a steam- generator built into the housing so steam is readily available providing for the fast healing process.

 We can custom build your autoclave to include quick cooling and other options specifically for your laboratory applications.

Roch manufactures autoclave in various sizes with different capacities. Request for Autoclave Machines, Autoclave Sterilizer, Dental / Flash Autoclave, Horizontal Autoclave (Cylindrical), Horizontal Autoclave (Rectangular), Laboratory Cement Autoclave, Portable High-Pressure Steam Industrial Autoclave, Vertical Autoclave Triple Walled and many more.

Autoclave Machines are also used in manufacturing applications, especially about mixtures, see autoclave machines (manufacturing).

Autoclaves machines are used to geld equipment and provide by exposing them to pressurized flooded steam at 121 °C (249 °F) for around 15–20 mint.

 

Why do we do autoclaving?

Reliable sterilization with moist heat requires temperatures above that of boiling water. These high temperatures are most commonly achieved by steam under pressure in an autoclave.

Autoclaving is the preferred method of sterilization unless the material to be sterilized can be damaged by heat or moisture.

 

For what purpose we use Autoclave?

Autoclaving is used to sterilize culture media, instruments, dressings, intravenous equipment, applicators, solutions, syringes, transfusion equipment, and numerous other items that can withstand high temperatures and pressures.

The laboratory technician uses it to sterilize bacteriological media and destroy pathogenic cultures. The autoclave is equally valuable for glassware and metalware and is among the first instruments ordered when a microbiology laboratory is established.

Autoclaves are also used on large industrial scale. Large industrial autoclaves are called retorts, but the same principle applies for common household pressure cooker used in the home canning of foods.

In large laboratories and hospitals, where great quantities of materials must be sterilized, special autoclaves, called pre-vacuum autoclaves, are often used.

This machine draws air out of the sterilizing chamber at the beginning of the cycle. Saturated steam is then used at a temperature of 132oC to 134oC at a pressure of 28 to 30 lb/in2.

The time for sterilization is now reduced to as little as 4 minutes. A vacuum pump operates at the end of the cycle to remove the steam and dry the load.

The major advantages of the pre-vacuum autoclave are the minimal exposure time for sterilization, the reduced time to complete the cycle and the costs of sterilization are greatly decreased.

Contents of an autoclave:

  1. Chamber

The chamber is the primary component of a steam autoclave, consisting of an inner chamber and outer jacket.

Laboratory and hospital autoclaves are constructed with “jacketed” chambers where the jacket is filled with steam, reducing the time that sterilization cycles take to complete and reducing condensation within the chamber.

Lab and hospital autoclave chambers can vary in size (from 100L to 3,000L). Chambers are typically constructed of 316L or Nickel-Clad (for inner chambers) and 316L, 304L, or Carbon Steel (for outer jackets).

  1. Controls System

All modern autoclaves are equipped with a controller interface, not unlike your microwave or oven.

Autoclave control systems are, however, a bit more sophisticated and complicated than those of your household appliance.

A sterilization cycle follows a software “recipe” that takes the process through a series of phases that involve the opening and closing of valves and components in a specific sequence.

Therefore, all autoclaves will require some form of controls, whether those as simple as a “push-button” system with a microprocessor or as complex as a Programmable Logic Controller with a color touch screen.

  1. Thermostatic Trap

All autoclaves will feature some form of thermostatic trap or steam trap, a device designed to allow air and water (condensate) to escape from the chamber.

Although various types of traps can be used in a steam delivery system/steam autoclave, they all perform the same function —removing condensate while allowing the passage of dry steam.

Most often, steam traps are temperature sensitive valves that close when heated past a certain setpoint.

Thermostatic traps are a critical component of any properly designed autoclave.

  1. Safety Valve

All autoclaves operate under elevated pressures (14-45 psi), therefore, must be manufactured with incredibly robust construction and fitted with a number of safety features and devices to ensure that they present no danger to users.

One of these safety devices is the safety valve. This is the final fail-safe device for the pressure vessel should all electronic controls fail.

It is imperative that the safety valve is inspected, tested and verified to be in proper working condition based on the recommendation of the sterilizer and/or valve manufacturer as well as local inspection and insurance agencies.

  1. Waste-Water Cooling Mechanism

Most autoclaves are equipped with a system to cool the effluent before it enters the drain piping. Many municipalities and buildings do not allow effluent above 140˚F to enter the floor drain.

In order to avoid damage to the facility’s drain piping, the steam must be cooled before it is finally sent down the drain.

The simplest, and oldest, the method of cooling the steam is to mix it with additional cold tap water, but the amount of water required can make autoclaves the single biggest contributor to a building’s water use.

Some autoclaves come equipped with systems designed to cut down, or even eliminate, this water consumption.

  1. Vacuum System (if applicable)

The primary concern for ensuring sterilization is making certain that all the air inside the chamber is replaced with steam.

Certain commonly sterilized goods, particularly porous materials like animal bedding or cloth, or containers with small openings like large flasks or goods in plastic bags, tend to retain air pockets when the autoclave only relies on displacing the air by pushing steam into the chamber.

If an air pocket is present during the cycle, any microorganisms within that pocket will survive and the goods will not be sterile.

For this reason, many sterilizers will include a vacuum system.

Not only does this allow you to forcibly remove air by pulling a vacuum on the chamber before a cycle (also known as pre-vacuum), it also helps the user by pulling a vacuum after the cycle (also known as post-vacuum) to remove the steam remaining in the chamber and dry off the goods inside the autoclave.

  1. Steam Generator (if applicable)

The most common steam source for a laboratory autoclave is from a central “house” boiler. However, when house steam is not available or is insufficient for the autoclave, one must resort to an electric steam generator (also known as a boiler).

These boilers typically sit integral (i.e. underneath the chamber) to the autoclave and utilize electric heating elements to heat water and generate steam.
