Dental autoclaves medical class B for sterilization of handpieces and other equipment: overview, prices

TO sterilization of dental instruments Due to the complexity of the shapes and structures, special requirements are imposed.

High-class autoclaves are designed for such procedures. They are irreplaceable in dental surgery and therapy, laboratories.

Why is class B needed?

An autoclave is a special apparatus for sterilizing instruments. The principle of operation of such devices is to process all working accessories with hot steam.

All autoclaves are divided into 3 categories:

1. Class B - multifunctional devices with the highest degree of sterilization. They disinfect instruments from any materials and shapes. The autoclave is used to process complex structures, including for dental handpieces. Vacuum pre-treatment and further drying takes place.
2. Class S - average degree of processing. Suitable for tools of simple design. Processing takes place without a vacuum component, only vacuum drying is present. The devices are characterized by efficiency, but they cannot provide complete sterilization, for example, dental handpieces.

3. Class N - do not have a vacuum chamber. Simple solid tools are processed in them, without any sections, grooves. Also suitable for plastic accessories that can withstand temperatures up to 121 degrees. The procedure is performed without sterilizing packaging.

In dental practice, category B devices are used. Devices surpass other classes of sterilizers in disinfecting abilities. They provide a high level of sterilization, kill all existing microbes, work with different materials and shapes. Distilled or demineralized water is intended for the apparatus.

The standard category B device has 3 disinfection programs:

1. Phase 1 - carried out at a temperature of 121 degrees. Takes 15 minutes.
2. Phase 2 - 18-25 minutes for packaged supplies. Temperature range - 135 degrees.
3. Phase 3 - carried out at 135 degrees. Takes 5 minutes, designed for instruments without packaging.

How does the autoclave sterilization process take place? The procedure is carried out using very high temperature steam in the absence of air. Many dental devices are complex in shape and design.

Hard-to-reach cavities contain air. Steam does not enter such places, which makes the treatment ineffective. For this, a vacuum function was introduced. The air is eliminated by the differential pressure. After that, the steam enters the cavities and carries out a complete disinfection.

An important function from the point of view of sterilization is vacuum drying. After vacuum pre-treatment, moisture remains on the surface of the instruments. Drying removes moisture to ensure complete sterility. As a result, the doctor receives a disinfected product.

The advantages of class B autoclaves:

• the effectiveness of the disinfection process;
• short sterilization time;
• reliability and economy;
• versatility - suitable for all dental instruments;
• a high level of sterilization without burning out instruments (as in dry heat).

Tips for choosing an autoclave

Tabletop steam sterilizers are intended for professional use only. They are used in accordance with the instructions for use and safety rules. They are used strictly for their intended purpose, only qualified specialists are allowed to operate. This rule applies to installation and connection.

When choosing an autoclave, pay attention to the following points:

• control type - manual, semiautomatic, automatic;
• the need to connect to communications or a closed cycle of the device;
• installation type - desktop / stationary;
• ease of management and simplicity of the interface;
• number of processing programs: standard version - 3 programs;
• method of cleaning equipment;
• additional functionality - a cooling fan, protection against opening, filters, ventilation and the like;
• the terms of the warranty obligation are taken into account.

All devices differ in terms of technical criteria and the amount of additional functionality. This affects the final cost. The volume of the sterilization material is also important. From these considerations, the appropriate chamber volume, the number of compartments, and so on are selected.

Attention should be paid to the dimensions of the device. So, with the same dimensions of sterilization chambers, the devices can differ significantly in size due to the design features.
