Abstract: An apparatus for movable fastening of a laboratory unit to a horizontally extending, elongated ceiling beam which is mounted in the region of a room ceiling and has at least one first groove which extends in the lengthwise direction of the ceiling beam. The apparatus includes: (i) a sliding element engageable with the first groove of the ceiling beam such that the apparatus is movable in lengthwise direction of the first groove, wherein a height of the sliding element is substantially equal to a height of an access opening to the groove, (ii) a retaining element for detachably fastening the laboratory unit, and (iii) at least one locking element which can be connected to the ceiling beam such that the apparatus is prevented from moving in the lengthwise direction of the first groove.

Abstract: The present invention relates to a media supply device for barrier-free, selective supply of laboratory media to at least one school or laboratory workstation. The media supply device comprises a body and a multiplicity of fittings for the supply and removal of laboratory media, which fittings are adjustable in height relative to the body and are coupled to the latter, and it is characterized in that the coupling between the fittings and the body is such that the fittings are movable in rotation about at least one oblique rotation axis deviating from a horizontal and vertical rotation axis.

Abstract: The invention relates to a laboratory fume cupboard (100) comprising, connected in a moveable manner with a laboratory housing (60), a sash (30) for opening and closing a fume cupboard interior, in which between the sash (30) and a side post (10) of the laboratory housing (60) an air opening (70) is provided which is designed for producing wall flows in the interior of the fume cupboard.

Abstract: A cabinet with a housing, in which a working chamber (3) is located which is open on one side. In order to reduce the risk of a blow-out of harmful substances and in particular to avoid dead-space areas at the internal surfaces of the side walls and the bottom of the working chamber (3), devices are provided which blow in supply-air jets (21, 22) at an acute angle to the internal surfaces of working chamber (3) in such a way that these supply-air jets (21, 22) lie next to the internal surfaces. Furthermore, an upper free jet (18) ensures that light gases, which form in working chamber (3) above this supporting jet (18), are reliably contained in the upper area of the cabinet and cannot contaminate the lower working area.

Abstract: The invention relates to an extractor apparatus (10), in particular a laboratory extractor apparatus, with a working area (13) and with a fan arrangement (26) for generating an air flow (27) or an inlet opening for an air flow (27) for the removal of gases and/or particles from the working area (13) and with at least one surface bordering the working area (13). The extractor apparatus (10) has charging means (30) for ionising the air flow (27) and/or for electrostatic charging of at least one surface.

Abstract: Media channel (1) for a laboratory system, more particularly a media cell, media column, suspended media boom or media station, for supplying a laboratory workplace with and/or removing laboratory media comprising a longitudinal profile element (100) which along its longitudinal axis defines a duct (102, 104) for laboratory cables and pipelines and has a supply and/or removal side and at least one panel (2, 2a, 2b), which is in the form of a blank panel or is equipped with at least one function-specific fitting for laboratory media supply and/or removal, whereby the panel (2, 2a, 2b) is detachably connected to the profile element (100) by means of connection elements (121, 125) provided on the supply and/or removal side of the profile element (100), and whereby the profile element (100) and the connection elements (121, 125) are in one piece in the form of a folded metal component.

Abstract: The invention relates to a laboratory fume cupboard (100) comprising, connected in a moveable manner with a laboratory housing (60), a sash (30) for opening and closing a fume cupboard interior, in which between the sash (30) and a side post (10) of the laboratory housing (60) an air opening (70) is provided which is designed for producing wall flows in the interior of the fume cupboard.

Abstract: A device for regulating the air volume flow for a laboratory exhaust, has a rectangular housing (6) which can be arranged on the laboratory exhaust. The device is equipped with inflow devices that can be connected to the interior of the laboratory exhaust and with outflow devices (8, 12, 13) that can be connected to an exhaust air system. The interior of housing (6) is divided by a partition (17) into two parts, namely a calming part on the exhaust side and a measurement and regulating part on the outflow side, and these two parts are connected by an air deflection area (18). A rectangular measurement orifice (20, 25) has pressure measurement devices (22, 23, 24, 28, 29) and a rectangular regulating flap (21) arranged one after the other at a distance in the direction of flow between a housing wall and the partition (17).
