Abstract

A heat-insulated sealed laboratory cabinet has a pressure equalization pipe (16) with a shut-off valve (12) to the outer atmosphere, where the valve has a closure (12) that is effective when located at the mid-point, and the closure is subjected to both atmospheric pressure and air cabinet pressure. A heat-insulated sealed laboratory cabinet has a pressure equalization pipe (16) with a shut-off valve (12) to the outer atmosphere, where the valve has a closure (12) that is effective when located at the mid-point, and the closure is subjected to both atmospheric pressure and air cabinet pressure. When there is pressure differential the closure (12) can move in either direction. An independent claim is also included for a heat-insulated laboratory cabinet equipped with a commensurate air pressure equalisation value.
