ABSTRACT:
The invention pertains to a safety cabinet with an interior enclosed by a housing and with a housing front comprising a working opening that can be closed with a height-adjustable front pane. The safety cabinet exhibits a fixed operating unit for controlling device functions that is integrated into the housing. A remote operating unit for controlling device functions that is spatially separated from the safety cabinet is also present. A receiver for receiving control signals emitted by the remote operating unit is also integrated into the safety cabinet. The remote operating unit not connected to the housing of the safety cabinet can be taken into the interior of the safety cabinet and removed from it by the operator without the necessity for the hands to touch nonsterile areas to operate the safety cabinet. Thereby the danger of contamination by entraining contaminants from the exterior into the interior is markedly reduced.
