Types of Autoclave Machines

When it comes to sterilisation in medical, laboratory, and research settings, autoclave machines are indispensable. These machines use steam under pressure to eliminate harmful bacteria, viruses, and fungi, ensuring a sterile environment for instruments and materials. The types of autoclave machines available today vary widely based on their design, functionality, and size. This article will help you understand the different types of autoclave machines, their classifications, and their specific uses in healthcare and other industries. By the end of this guide, you will know how to choose the right autoclave machine for your needs and explore financing options through Bajaj Finserv Medical Equipment Finance to help you make an informed decision.

How are the different types of autoclave machines categorised?

Autoclave machines are broadly classified based on their function, class, and size. Each type serves a specific purpose and comes with unique features to suit different sterilisation needs.

1. Different types of autoclaves categorised by function

Autoclaves can be categorised based on their function, ranging from vertical and horizontal types to gravity displacement and pre-vacuum autoclaves. Each type offers distinct advantages depending on the sterilisation requirements.

Vertical autoclaves

Vertical autoclaves are compact and ideal for small labs or medical setups with limited space. They open from the top and are best for sterilising laboratory glassware, culture media, and more.

Horizontal autoclaves

Horizontal autoclaves are larger and more powerful, suitable for hospitals and larger medical facilities. They provide better efficiency and have a higher capacity, making them perfect for sterilising surgical instruments and larger loads.

Gravity displacement autoclaves

These autoclaves use gravity to remove air and replace it with steam. They are cost-effective and commonly used in laboratories for sterilising non-porous items.

Pre-vacuum (Prevac) autoclaves

Pre-vacuum autoclaves remove air before steam is introduced, providing a deeper and more effective sterilisation. They are ideal for porous materials, making them suitable for hospital settings.

2. Different types of autoclaves categorised by class

Autoclaves are also classified based on their sterilisation standards into Class N, Class S, and Class B.

Class N autoclaves

Class N autoclaves are suitable for simple instruments without hollow spaces. They are the most basic type and are generally used in clinics.

Class S autoclaves

Class S autoclaves offer a middle ground between Class N and Class B. They are versatile and can handle a variety of loads, including textiles and wrapped instruments.

Class B autoclaves

Class B autoclaves are the most advanced, capable of sterilising complex instruments, including hollow items. They are ideal for dental practices, hospitals, and surgical centers.

3. Different types based on the materials that are used to manufacture autoclave machines

In the past, autoclave manufacturers used nickel-clad, highly corrosion-resistant materials to build sterilizers. However, modern laboratory autoclave machines have significantly advanced, offering superior construction and performance. Today’s autoclaves are commonly made from materials such as stainless steel and aluminium, which provide improved durability and efficiency.

Stainless steel autoclaves: Stainless steel autoclaves are widely used due to their excellent properties, such as strength, resistance to corrosion, and durability. However, some misconceptions about the material's versatility may lead to premature corrosion if not properly maintained. These autoclaves are ideal for a variety of sterilization tasks.

Suggested stainless steel autoclaves include high-pressure steam sterilizers, which are commonly used for sterilizing medical instruments, lab equipment, and materials under high pressure.

Aluminium autoclaves: Aluminium autoclaves are preferred for certain applications due to their cost-effectiveness and lower water consumption. They require less water to generate dry steam, making them a more economical choice. These autoclaves are particularly useful for sterilizing medical items like dressings and surgical instruments under high-pressure steam.

Some recommended aluminium autoclave machines include the Surgix Autoclave Electric Aluminium Cooker Type and other electric cooker-type autoclaves, which offer reliable performance in medical and laboratory settings. These options are cost-efficient and highly effective in sterilization.

4. Different types of autoclave based on the different power sources

Electric autoclave machine

• Function: Uses moist heat sterilisation to sterilise equipment by creating saturated steam under pressure, effectively killing microorganisms.
• Power source: Runs on electricity, making it eco-friendly and efficient.
• Applications: Ideal for medical, laboratory, and clinical settings to sterilise medical instruments and tools.
• Examples:
  • Electric autoclave machine
  • Stainless steel autoclave
  • Portable steam autoclave

These autoclaves are portable, durable, and designed for ease of use, providing a reliable and safe sterilisation method.

Non-electric autoclave machine

• Function: Operates without electricity by being heated using an external heat source, such as a stove.
• Applications: Suitable for locations where electricity is unreliable or for users preferring traditional sterilisation methods.
• Examples:
  • Non-electric autoclave machine, stainless steel - portable (21ltr)
  • Portable autoclave machine, non-electric stainless steel (27ltr)
  • Steam steriliser machine, non-electric stainless steel (39ltr)

These machines provide a cost-effective and portable solution for sterilisation in areas with limited or no electricity. They offer a practical alternative to electric autoclaves, especially in remote or off-grid locations.

Benefits of autoclave machines

Autoclave machines offer numerous benefits, such as effective sterilisation, reduced risk of infections, and versatility in handling various types of materials. They help maintain a sterile environment, which is critical in healthcare and laboratory settings.

Choosing the right autoclave for different needs

Choosing the right autoclave involves considering several factors like the type of material to be sterilised, the volume of sterilisation required, and the available space. Evaluating these aspects will help you decide whether you need a vertical, horizontal, or other type of autoclave machines.

Financing options for buying autoclave machines

Purchasing an autoclave machine can be a significant investment. To ease the financial burden, consider exploring financing options like a Medical Equipment loan from Bajaj Finance. These loans come with flexible repayment options, ensuring that you can get the best equipment without straining your budget.

Conclusion

Autoclave machines are essential for maintaining hygiene and safety in medical and laboratory settings. With various types available, selecting the right one depends on your specific needs. If you are looking for financing options for medical professionals, you may also consider a doctor loan from Bajaj Finance to help you acquire the necessary equipment.
