BMB-III-“Laminar-S”-1,2 PROTECT VIS-À-VIS Class III

Article 2E-C.002-12

The cabinet is designed for operators working simultaneously opposite one another.
The system of monitoring with the audio-visible indication system warns operator about the failure of working modes in the cabinet.

Application of the Biological Safety Cabinet Class III:

  • Reduction of risk of infection of an operator working with airborne pathogenic agents and microorganisms, protection of the environment as well as the product from external contamination and cross-contamination
  • Protection of an operator and environment from airborne infection when working with pathogenic biological agents (PBA) and microorganisms including highly (especially) hazardous pathogenic groups.
  • Protection of the work agents inside the work chamber from external contamination.
