Air is pulled in under the doors, up through the specimen shelves into the head unit.
The air then passes through a carbon filter to remove the fumes and odorous and filtered sir is then returned to the laboratory. Alternatively, the air can be ducted directly to the outside. Sliding doors on the unit allows easy access to all shelves and the unit occupies the minimum of space. The perforated shelving is constructed in 316 grade stainless steel for ease of cleaning. A spillage tray in the base contains any material spills from broken containers.
