Biological safety cabinets

Biological safety cabinets are specialized equipment designed to work with samples that may contain dangerous biological agents. Their design includes filters for air purification, a chamber for placing materials, as well as protective mechanisms that ensure isolation of the working area. Thanks to their special design, these cabinets create a safe working environment, preventing the spread of microorganisms and aerosols outside the working chamber.

Such offices are equipped with an air circulation system that passes through a highly efficient HEPA filter, which traps up to 99.97% of particles with a size of 0.3 microns. This allows you to keep potentially dangerous substances inside the office, protecting employees and the premises from contamination.

The main classes of the biological safety box cabinet

Biological protection cabinets are divided into several classes depending on the level of protection they provide:

1. Class I. Boxes provide protection for the operator and the environment, but do not protect the sample itself. The air enters the working area, where processing is carried out, and then it is filtered and leaves the office. This type of cabinet provides a basic level of security and is often used in institutions where there is no need to protect the sample itself.
2. Class II. These boxes provide protection for both the operator and the environment and the sample itself. Includes various models that differ in the air circulation system and the level of filtration. For example, class II models are divided into types A and B, where each type has its own characteristics in the use of air flows and filtration. Class II biological safety boxes are widely used in medical and research laboratories.
3. Class III. These are highly protective boxes, cabinets designed for working with the most dangerous biological agents. Cabinets are fully hermetic, with a double air filtration system and a fully enclosed sample chamber. The use of such cabinets allows working with materials that have a particularly high risk of contamination, and is often found in laboratories with the highest level of protection.

Where are biological safety cabinets (boxes) used?

Biological safety cabinets are used in a wide range of facilities that require protection from potentially dangerous biological agents:

• Laboratories of biotechnology and genetic research, where experiments are carried out with living organisms or viruses.
• Medical institutions - boxes are needed for work with infectious agents, tests and medical materials.
• Research centers and institutes have boxes where experiments are conducted with samples of various origins.

Due to the high level of protection and ergonomic design, these cabinets become indispensable in work where reliable protection is required. For example, biological safety cabinets are often used when conducting studies with infectious samples. In addition, models with an energy saving program are available, which ensures efficient use of resources.

Advantages and characteristics of biological safety cabinets

Biological safety cabinets combine many modern technologies for maximum convenience and safety:

1. Ergonomic design for comfortable work of operators.
2. Highly efficient HEPA filters that provide continuous air filtration.
3. Different models that can be adapted to different operating conditions.
4. Built-in accessories to facilitate the work process.

Many official manufacturers offer these cabinets with various technical characteristics that meet European quality and safety standards. To ensure the durability and efficiency of the cabinet, it is important to follow the maintenance instructions and carry out regular technical inspections.

Biological safety cabinets are an indispensable element in laboratories, medical institutions and research institutions, where they work with biologically hazardous materials. They create a controlled working environment, ensuring the protection of personnel and samples thanks to a special system of filtration and air circulation. Such a mechanism makes these cabinets a reliable tool for protecting people's health and the environment.
