BMB-III-“Laminar-S”-1,8 PROTECT VIS-À-VIS Class III
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.

Standard Configuration
Work Chamber
- work chamber is made of stainless steel AISI 304;
- hinged front sashes made of laminated safety glass resistant to UV and disinfectants;
- each front window has four oval-shaped glove ports; the glove ports are featured with catches and guides for self-contained glove integrity testing module (not part of the delivery set; can be supplied as an additional option);
- each glove port is equipped with a chamber glove with silicon O-ring.
- liquid-collecting tray made of stainless steel AISI 304 without drain located in the bottom part of the work chamber;
- 2 LED lighting sets in the work chamber;
- two removable electric sockets in the work chamber (on the left side wall);
- UV light in the work chamber;
- pressure gauge from -500 Pa to +500 Pa.
Supply and Exhaust Air Filtration System
- two-stage filtration of the air coming into the work chamber: prefilter G4 and supply HEPA filter H14 located over the work chamber;
- two-stage filtration of the exhaust air coming out of the cabinet: two successive exhaust HEPA filters H14.
Pass Box
- outer panels of the pass box are made of powder-coated metal;
- inner chamber is leak-tight and made of stainless steel AISI 304;
- corner door location: the outer door in front of the cabinet, the inner door built into the side wall of the work chamber;
- pass box doors a equipped with handles made of stainless steel AISI 321;
- pass box doors are featured with electromechanical interlocks for preventing simultaneous opening of both of the doors;
- door windows are made of tempered glass;
- two UV lamps;
- LED lighting;
- pullout perforated tray made of stainless steel AISI 304 ensures simple transferring of objects from the pass box into the work chamber and UV irradiation of the bottom of the transferred materials.
