Embodiment Construction

[0026] figure 1 A cross-sectional view of a Class II safety cabinet is shown, which corresponds to conventional safety cabinets as far as their main construction is concerned. The safety cabinet 1 comprises a working space 3 for the safe handling of samples, which is enclosed by a housing 2 . The workspace 3 can be sealed on the front side by a front window 4 which is movable upwards and downwards. The safety cabinet according to the invention differs from conventional safety cabinets in that it comprises a projection device 5 by means of which images can be projected from outside into the workspace. In the indicated case, the projection device 5 is fastened to the housing 2 of the safety cabinet 1 by means of fastening means 9 which in this case appear on the front side of the housing, substantially above the working opening, This working opening allows access to the working space 3 . The projection device 5 relates for example to a video projector which receives data from...

Description

technical field [0001] The present invention relates to a laboratory fume hood, and in particular to a safety cabinet having a work space enclosed by a housing, which can be closed with a front window and in which work space can be handled in a protected manner sample. Laboratory fume hoods and safety cabinets differ from each other in the protection they provide. Safety cabinets are currently subdivided into three classes based on the protection provided to the user and the handling of samples. Regulations in this regard can be found in the standards DIN EN12469:2000 and DIN 12980:2005. The present invention relates to all such devices, namely class I to III sample laboratory fume hoods, laminar flow cabinets and safety cabinets. All of these types of equipment will be referred to below in a generalized manner as laboratory fume hoods. Background technique [0002] To ensure the necessary protection in all situations in a laboratory fume hood, it is required to maintain...
