Working Principle - Telstar Bio II Advance Plus Serie Manual De Usuario

2. DESCRIPTION OF THE SAFETY CABINETS
2.1.

WORKING PRINCIPLE

CLASS II Biohazard Safety Cabinets are designed for microbiology work with the most
advanced microprocessor control, ensuring a high level of protection for the operator,
environment and sample.
Exterior of cabinet made of laminated, lacquered, oven-dried steel. Functional design with
reduced external dimensions and front access for changing filters.
Spacious internal chamber with sliding-swinging front made from laminated safety glass.
Segmented work surface and liquid collection tray made of polished stainless steel. Arm-rest
is detachable to facilitate cleaning of liquids tray.
Two-fan system (four in the Bio II Advance Plus 6) providing laminar and exhaust flow by
means of a shared plenum. In the case of a breakdown of any fan, the other ones continue
to provide airflow.
As can be seen in Annex A2, the air propelled by the fans (1) is moved into the chamber or
plenum (3) and, on the one hand via the Absolute HEPA filter (4), is filtered and flows
according laminar regime in the working area (6). On the other hand, part of the air flows
through an Absolute HEPA filter (5) before being expelled to the outside (8).
System of recycled (70%), sterile vertical laminar flow in depression and exhaust (30%)
sterile air, approximately.
2.2. APPLICATIONS AND PRINCIPLE DIAGRAM
The microbiological safety cabinet models are appropriate for handling biologically
pathogenic samples or products (up to micro organism risk BSL3), ensuring sterile air in the
work zone, as well as a high level of protection for the operator and the environment.
Principle diagram in Annex A1.
WARNING
Under no circumstances, is possible handling in corrosive, flammable or explosive gas
ambient.
It is recommended that extracted air should be expelled to the exterior.
Right working conditions are obtained only when the display is green and without any alarm
message on the display.
