An open fume capture and exhaust work station for a laboratory classroom having an air exhaust system that provides unobstructed sight lines for students at the station of the other students and of a classroom instructor. The work station includes an upper table surface providing a plurality of individual work surfaces, a fume extractor extending upwardly from a middle portion of the table surface to an elevation below the student sight lines, a pair of elongated air outlet openings adjacent to opposed sides of the table for directing fan generated opposed airflows to the extractor which defines opposed upstanding air inlet faces and communicates those faces with the air exhaust system creating a pressure drop within the extractor that captures the opposed inwardly airflows and pull the airflows over the individual work surfaces and into said extractor, capturing and removing emissions from spills and experiments on those work surfaces.

Systems, apparatus, and methods of manufacturing an article using electroadhesion technology for the pick-up and release of materials, respectively.

Systems, apparatus, and methods of manufacturing an article using electroadhesion technology, either as a sole modality of handling such materials or in concert with at least one mechanically actuated modality for the pick-up and release of materials, respectively.

A welding table may include a table top and one or more legs coupled with the table top. The table top and the one or more legs may be electrically conductive. To inhibit an electric charge from being transmitted from the table top to the one or more legs, the one or more legs may be electrically isolated from the table top. By electrically isolating the one or more legs from the table top, electrical equipment associated with the welding table may be protected from damage, such as electrical burnout. In certain implementations, the one or more legs may be height adjustable, and electrical equipment for adjusting the height of the one or more legs may be protected from damage by electrically isolating the one or more legs from the table top.

A movable workbench for performing work under low temperature, such as 80 C. or below. The movable workbench includes: a worktable including a workspace forming member for providing a workspace for work at low temperature and a refrigerant-reservoir for containing a refrigerant, and disposed on a base with a moving member; the workspace forming member including side and bottom walls providing a workspace with an upper surface opening; the upper surface of the workspace being open on the upper side of the worktable; the refrigerant-reservoir accommodating the bottom wall of the workspace forming member so that a gas phase in the workspace is cooled when the refrigerant is provided in the refrigerant-reservoir and the bottom wall of the workspace forming member is subsequently cooled; and the moving member disposed on a bottom surface of the base so that the worktable is movable with the refrigerant-reservoir filled with the refrigerant.

A weighing fume cupboard (1) for weighing pharmaceutically active or toxic substances in a laboratory, comprising a housing (10) which defines a working space (19), wherein a front side of the housing (10) has a working opening (11) which is open at all times during intended use of the weighing fume cupboard (1), a working plate (20) which delimits the working space (19) at the bottom side, an armrest (40) in the region of the working opening (11), and a support (30) which bears the weight of the housing (10), of the working plate (20) and of the armrest (40), wherein, during intended use of the weighing fume cupboard, the working plate (20) is decoupled in terms of shocks and vibrations from the housing (10), from the armrest (40) and from the support (30).
