Biological Safety Cabinets offer protection from microbiological contamination in the laboratory environment, including both operator and product protection.

They are utilized by a wide range of scientific, research and development organizations within both the commercial and non-commercial sectors, including pharmaceutical, medical, clinical research, defense, education and general healthcare sectors.

Biological safety cabinets provide:

  • Isolating equipment for biomedical research
  • Safety devices for biological hazard prevention
  • Laboratory equipment performance testing
  • Occupational hygiene and safety
  • Environmental cleanliness
  • Disease de-contamination and prevention

They are most commonly used in biotechnology, pharmaceutical and clinical laboratory processes.


Class 1 Biological Safety Cabinet

A Biological Safety Cabinet with a working front aperture through which the user can carry out manipulations inside the cabinet. It offers operator protection via inward airflow allowing the escape of airborne particles generated within the cabinet with the aid of HEPA filtration of the exhaust air.  Class I Cabinets offers protection for the user but no protection for the work.

Class 2 Biological Safety Cabinet

  • A Class 2 Biological Safety Cabinet has a front aperture through which the operator can carry out work inside the cabinet. Notably, it provides both worker and materials protection.
  • Class 2 Biological Safety Cabinets are the most in use bio-containment devices protecting worker, product and environment from potentially dangerous microbiological agents.
  • A Class 2 Biological Safety Cabinet is designed to control airborne contamination of the work and reduce risks of exposure of the operator to any airborne particles dispersed within the cabinet from the work procedures.

Class 3 Biological Safety Cabinet

Class 3 Microbiological Safety Cabinets provide total barrier protection for the operator and are suitable for extreme bio-hazard work. Inflow air is HEPA filtered before entering the Class 3 Biological Safety Cabinet via a side mounted inlet filter chamber. Exhaust air is HEPA filtered before leaving the safety cabinet via a single or double HEPA filter, dependent on the customer’s specific technical requirements.

  • Total enclosure of the working area
  • User separated from the work by a physical barrier
  • Filtered air continuously supplied to the safety cabinet
  • Exhaust air treated to prevent contamination
  • Creates total protection for user and materials

Manipulations within the Class 3 Biological Safety Cabinet are carried out via gloves mechanically attached to the cabinet providing a total seal against any particulate contamination released within the main working area. 

Scientific Instrument Center, Inc. certifies fume hoods, biosafety cabinets, and clean rooms. Certifications are to meet ANSI/ASHRAE 110 for fume hoods and NSF 49 for biosafety cabinets like isolator type cabinets repair in Ohio. Clean rooms are certified to the requirements of ISO 14644 and USP 797 for pharmacies. Decontamination and all service can also be performed on biosafety cabinets, and fume hoods as well. Also includes certification of all laminar flow benches, grossing stations, and isolator type cabinets.
