Biosuojakaappeja

Biosuojakaappeja, also known as biological safety cabinets or fume hoods, are specialized enclosures used in laboratories to protect both the user and the environment from hazardous biological agents or chemicals. They create a controlled environment by drawing air inwards, filtering it through HEPA (High-Efficiency Particulate Air) filters, and then exhausting it. This filtration process effectively removes airborne particles, including microorganisms, ensuring that any potentially harmful substances are contained.

There are different classes of biosuojakaappeja, each designed for specific levels of protection. Class I cabinets are primarily for operator protection, drawing air away from the user. Class II cabinets offer both operator and product protection, with a portion of the filtered air recirculated within the cabinet. Class III cabinets provide the highest level of containment, operating as a glove box with a completely sealed system, making them suitable for work with highly infectious agents.

The primary function of biosuojakaappeja is to prevent the escape of infectious aerosols into the laboratory or the wider environment. They are crucial for research involving pathogens, cell cultures, and sterile procedures. Proper use and maintenance, including regular certification and filter replacement, are essential to ensure their continued effectiveness and the safety of laboratory personnel. They are a fundamental piece of equipment in many biological, medical, and chemical research facilities.
