Biosafety cabinets are a type of biocontainment equipment that is used in biological laboratories, research institutions, and diagnostic testing & laboratories to provide containment and protection from pathogenic microorganisms such as cell cultures, human or animal tissues, viruses, aerosols, chemical fumes, and hazardous chemicals used inside the hood to the operator, product, and the environment. They form an integral part of laboratories as it shields the user and the environment from the harmful effects of cross-contamination, which could lead to a person getting infected with aerosols or viruses and further endanger the lives of the people that come in contact with it, as these can be fatal for humans and animals. Hence, ensuring the safety of people with access to these samples plays an important role. The different types of biosafety cabinets can be used based on the level of biosafety required, thereby propelling the growth of the global biosafety cabinets market during the forecast period.
