<p>The device (1) has ceiling supports i.e. longitudinal bars (111), connected with a ceiling (2) of a laboratory with a columnar structure. The supports include upper and lower pillar portions (100, 10U). A cantilever arm (112) is connected with the structure in the upper pillar portion, and bears a medium channel (114) with medium spacers (91-93). Each medium spacer is guided to connectors (31-33) in the lower pillar portion. The arm is disguised with panels (10A-10C). One of the panels is connected with the connectors, and the other panel is releasably swingably connected with the structure. The columnar structure is designed as a transverse strut.</p> |
