BMB-III-"Laminar-S."-1,2 PROTECT Class III
Article 2Е-С.001-12
The model design allows using those cabinets for work with deadly bacteria and viruses.
If connected to the individual active exhaust system, the cabinet could be used for protection from small amounts of toxic chemical substances and radionuclides.
The system of monitoring with the audio-visible indication system warns operator about the failure of working modes in the cabinet.
Key Benefits
- The cabinet has a sealed PASS-THROUGH SLUICE GATE made of stainless steel.
- A PULL OUT SLUICE TABLE TOP makes loading objects into the working chamber easier.
- FRONT SASH can be lifted for equipment loading. It is made of laminated safety glass and equipped with two oval glove ports.
- REMOVABLE OUTLET UNIT in the working chamber with self-powered shutoff function.
- The design of the cabinet allows integrating several cabinets in one line for continuous technological process.
Application of the Biological Safety Cabinet Class III:
- 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.
- If connected to the individual active exhaust system, cabinet can be used for work with toxic chemical substances and radio nuclides in low quantities and for odor removal from the work agents.
- Cabinet is designed to equip workstations in the medical, pharmaceutical, and other institutes working with microorganisms of I-II-III-IV pathogenic groups and with parasitic disease agents
