A housing for a laboratory appliance with a floor, ceiling, rear wall, side walls and front wall, which together enclose a work space. The front wall is movable between closed position and open positions. A work area in which liquids can be handled is provided in the work space. A filter device for ambient air is connected to the work space via at least one air outlet. At least one air inlet is connected to the environment, and a fan and an air filter are located downstream from the air inlet and upstream from the air outlet. An outflow opening is also located on the housing. The at least one air outlet and the at least one outflow opening are arranged on the housing such that, during operation of the filter device, the filter air stream flows substantially parallel to and along the work area.

Laminar air flow workstation, comprising: a working chamber (1) comprising a work table (2), an air circulation system (3) comprising first heating means (4), and configured to circulate heated air in the workstation and direct a heated and temperature controlled air flow towards the work table (2), wherein the working chamber comprises a front handling opening (6) in fluid connection with the surroundings (7), and configured such that the work table (2) can be accessed from the surroundings (7). Also disclosed are the use of the workstation for handling and/or microscopy of biological materials, such as tissue, embryos, and stem cells, as well as the use of the workstation for microbiological safety workstation in accordance with ISO/EN 12469.

In a laboratory hood system having a housing with an access window opening into an interior work chamber for performing laboratory processes, and an air circulation system for creating an air flow from the laboratory environment inwardly through the access window into the work chamber for preventing hazardous materials from escaping into the laboratory environment through the access window, one or more air intake control devices are disposed in a selected location or locations at the access window to overcome any tendency for air turbulence to occur. The air intake control device has an air flow channel extending from an air intake opening to the laboratory environment to an air discharge opening to the work chamber, with a constriction in the channel for causing a venturi-effect increase in air velocity while flowing through the channel to promote non-turbulent air flow entering the work chamber at the selected location or locations.

The disclosure provides a multi-function ductless enclosure apparatus. Its main purpose is to be used as a paint spray booth to capture excess paint, pass it through filters with the use of a fan and then exhaust the ensuing clean air out, back into the room air. This booth is foldable and light weight and can be moved to a different location in minutes. It can also be transformed to serve many other applications with the use of a few accessories thereby saving the end user from having to have several booths (saving counter space) and also saving him from having to spend a lot of money buying many booths for different applications.

Exhaust capture and containment are enhanced by means of automatic or manual side skirts, a sensitive breach detector based on interference effects, a combination of vertical and horizontal edge jets, and/or corner jets that are directed to the center diagonally from corners. Associated control functions are described.

Certain exemplary aspects of the present disclosure are directed towards apparatuses and methods which autonomously decontaminate parts. Parts to be cleaned are identified, and based on the identification of the part, a part specific cleaning program is initiated. During the cleaning, the part is manipulated about a gas supply in such a way that the drag force on the contamination particles attached to the part exceeds the contamination particles' surface adhesion force and accordingly is removed from the surface of the part. The removed contamination is then evacuated from the atmospheric environment near the part by a low pressure zone of a second gaseous material near the part.

A safety cabinet has a second operation chamber in a first operation chamber and into which clean air is supplied, a second suction opening for sucking in air in the second operation chamber and a portion of the air in the first operation chamber, and a second operation opening part that is provided facing a first operation opening part and communicates the second operation chamber with the first operation chamber. Airflow containment (air barrier) is doubled with respect to the outside of a safety cabinet. In cases where decontamination and disinfection operations are carried out according to the changeover procedures, intensive decontamination and disinfection of the second operation chamber is sufficient, and decontamination and disinfection of the first operation chamber is hardly required. Decontamination and disinfection operations in the changeover procedures and the like can be carried out in a greatly reduced time.

A ventilated enclosure includes a vortex baffle to harness the turbulence of air in a way that uses less exhaust air while still providing ample protection to the user. The vortex ventilation system uses the total interior shape and proportion of the ventilated enclosure to direct the motion of air flow in a manner that improves efficiency. The vortex ventilation baffle can enhance the way air naturally curls, or rolls, as air flows through the enclosure. The vortex baffle can cause a mono-stable vortex to from in the enclosure. This vortex is resilient to disturbances that cause ventilated enclosures, such as chemical fume hoods, to spill. The stable vortex is above the work surface and less affected by the way apparatus is loaded inside the enclosure. The vortex baffle achieves better containment (improved safety) at lower exhaust flow (improved energy consumption) as compared to conventional ventilated enclosures.

Sample contamination is suppressed by strengthening the air barrier of a work opening portion. A safety cabinet includes: a work room; a front surface door covering a part of a front opening portion of the work room; and a work opening portion on a lower side of the front surface door allowing a worker to work with his or her hand in. An intake port suctions air in the work room and outside air through the work opening portion on a front surface side of a workbench in a lower portion of the work room. A straightening plate drawing an air flow and a linear light source are provided on the work room side of the front surface door and above a front portion of the work room.

A pass box configured to accommodate and decontaminate an article by concentrating a mist of decontamination agent on an article's surface and to reduce a duration of aeration operations. The box includes a decontamination chamber, an aeration chamber in which residue of the decontamination agent is removed from the article's surface, a decontamination agent supply device, a decontamination agent control device, a moving device configured to reposition the article, and an air supply and exhaust device. The decontamination agent supply device converts a chemical into the mist and supplies it into the decontamination chamber. The decontamination agent control device includes vibration boards that are adjacent to internal wall surfaces of the decontamination chamber and that are ultrasonically vibrated to generate sound flows in the vertical direction thereby pressing the mist with acoustic radiation to concentrate the mist on the external surfaces of the article.
