Purpose of the biological safety cabinet class II /type A2/ (code 221.150):

  • Physical isolation (retention and controlled removal from the work area) of pathogenic biological agents (PBA) and microorganisms in order to prevent the possibility of infection by airborne droplets of personnel and contamination of the air of the working room and the environment.
  • Minimization of the risk of contamination and cross-contamination of the product.
  • Ability to work with a small amount of toxic chemicals, radionuclides and remove odors of working agents with the obligatory connection of the box to an individual active exhaust ventilation system using an exhaust hood, which is supplied by an additional order.

Use of a biological safety cabinet class II /type A2/:

The box is designed to equip individual workplaces of medical, pharmaceutical and other institutions that work with pathogenic biological agents and microorganisms in accordance with SP 1.3.2322-08, SP 1.3.2518-09, SP 1.3.3118-13.
