3.5 Lighting in working chamber
All Fortuna has built in light in the working chamber. All cabinets are fitted with two florescent light
tubes mounted at the top of the working chamber to avoid disturbances of the airflow. This position
above the laminator gives a good and uniform light on the entire working area. The control system
allows the user to adjust the intensity from 0 to more than 750 Lux. The reachable light level is about
2000 Lux in the standard cabinets, measured on the table tops. LED light can optionally be delivered.
Please refer to Options paragraph.
3.6 UV light
The optional, factory-installed UV light is at the top of the front section of the working chamber. The
standard LaboGene control system is prepared for full control of safety and timing for the use of UV
light – see section “UV light option” for operation and build in safety measures.
Remember that UV light does not penetrate areas blocked from the direct light and that it does not
represent a substitute for good old fashion mechanical cleaning of the inner surfaces of the safety
cabinet.
3.7 Working area
All Fortuna cabinets are, as default, delivered with one solid fixed table top. They are designed for
easy cleaning, minimum vibrations and maximum working area. As standard it is made of 2 mm
stainless steel plate (AISI 304) wrapped around a chipboard for rigidity.
4 Installation of the Fortuna cabintes
4.1 General considerations
A sterile cabinet is a ventilated cabinet, which provides product protection. It has an open front and
back with outward airflow and downward HEPA filtered laminar airflow over the entire working area
for product protection.
The cabinets are neutral with respect to pressure in the room, as all air drawn into the cabinet is
exhausted back into the room.
