An Introduction to Сlass II Biological Safety Cabinets

Biological safety cabinets (BSC) date back to the early 20th century. Older versions looked like ordinary cabinets with exhaust ducts attached to them. In the 40s, a researcher named Van den Ende described a device that resembled modern BSCs. It used a furnace to create an inward airflow and incinerate the exhaust air.

Today, laboratories around the world have access to these devices, with the Сlass II Biological Safety Cabinet being the most common. These provide an adequate level of protection through the use of HEPA filters. These hoods can contain up to risk level 3 pathogens. They are widely used in the following industries:

  • microbiology;
  • toxicology;
  • biotechnology;
  • immunology;
  • chemistry.

The four types of this class of BSC mean that there are products to fit completely different laboratories. They differ in terms of airflow patterns, filtering types, and exhaust systems. This equipment can prevent laboratory-acquired infections, cross-contamination of samples, and environmental release of pathogens. A Сlass II Biological Safety Cabinet creates a clean and safe work zone for handling infectious agents or microorganisms.

If you have a small research space, such as a 3×9 m room (e.g. a wet lab module), this Class II Biosafety Cabinet will be a perfect fit. The dimensions of the cabinet, including the stand and the exhaust hood in assembly, are 1200х770х2175 mm. It is designed to contain materials that are dangerous to the human body or the outside environment.

The transparent frontal sash can be raised to access the inner chamber. This does not make the handling of hazardous materials any less safe due to the downward and upward airflow. All the dangerous particles stay inside the working space to be exhausted later through the ducts into the outside environment.

Before that, contaminated air will be filtered. High-Efficiency Particulate Air (HEPA) filters should be replaced when they are no longer able to fulfil their functions. Additional filters can be bought separately.

This Class II Biosafety Cabinet is a versatile device with dimensions of 1500х770х2175 mm that can suit your medium-sized research space, such as a 6×12 m room. These devices are most commonly used in medical and biological laboratories for handling dangerous pathogens. Industrial chemistry research is another field where these BSCs are often used.

Inside the working chamber is a space with a laminar airflow that prevents the contamination of the outside air and cross-contamination between the samples. The basic configuration of this device can provide:

  • UV lamp placed outside of the inner chamber;
  • removable armrest;
  • footrest on the frame;
  • standard voltage electrical outlets inside the inner chamber;
  • alarm system
  • glass frontal sash with dampers.

For a large research space, such as a 9×15 m room that can accommodate a complex lab layout or multiple researchers, you can choose this Class II Biosafety Cabinet with dimensions of 1800х770х2175 mm. It can handle hazardous materials and protect employees from danger. Additional modules are optional accessories that can be installed on the cabinet:

  • An adjustable stand that allows the user to change the height of the cabinet to suit their ergonomic needs.
  • A vacuum tap with an electromagnetic valve that allows the user to connect a vacuum source to the cabinet for suction purposes.
  • A set of three ULPA filters that provides extra filtration of the air for greater efficiency and safety.
