Gas extraction hoods are equipment designed to protect the user, from chemical exposures and dangerous agents, during the study processes. The protection is achieved by the ventilation systems of the interior space, by an air flow caused through an adjustable working principle, also avoiding the discharge of pollutants into the environment.
This equipment addresses the need to control dangerous or irritating substances that are usually generated in the air, or released within the local ventilation device itself. According to this, gas extraction campaigns are used in chemical laboratories, where the user is exposed to pollutants, dangerous chemicals, etc., since it is an area equipped with the necessary means to carry out research, experiments, practices and scientific work.
Biological safety cabinets are ventilated rooms designed to limit the risk of laboratory personnel exposed to infectious agents as much as possible. This is especially important considering that many of the operations carried out in a laboratory involve the formation of aerosols. The main objective of this equipment is to provide a work area that minimizes the probability that an airborne particle has to escape to the outside of the cabin and thus contaminate the operator and the area around him. In addition, some of them offer protection to the material that is handled.
When a biological safety cabinet is used by properly trained personnel aware of its limitations, it becomes a very effective containment equipment to reduce the possible escape of biological contamination. However, it is important to bear in mind that a cabin is never a substitute for a proper microbiological technique.

In this section you can find, our Biosafety Hood and Cabinet in operation, packaged, receiving service, etc.
The protective mechanism offered by biological safety hoods is due to electromechanical/electronic elements (motor, fan, filter, ducts, lighting, etc.), and physical processes (laminar flow, pressure differences) that drive the air through strategically placed special filters of large surface, which have a minimum efficiency of retention of particles of 99.99%, when the size of the same is on average 0.3 µm (micrometers).
