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.

Laboratory ventilation is integrated. The HVAC room controller requests changes in the exhaust set point of one or more fume hoods. By allowing the fume hoods to respond to such HVAC requests, the fume hood exhaust may be turned down to a point below the highest level that could be needed. The request may be used to turn the fume hood exhaust back up, so greater energy savings may be possible in non-peak demand operation of the HVAC system.

Methods, systems, and apparatus are described which can safely reduce a laboratory fume hood's minimum airflow and energy consumption when it is determined that the fume hood is not in active use, based on a condition monitoring approach. The condition monitoring approach may incorporate a combination of setback criteria to reliably determine if the fume hood is or is not in use. When a determination has been made that a fume hood is not in use, energy reduction is achieved via automatic methods of hood minimum airflow setback. Fume hood minimum flow reductions are automatically disabled when it is determined that the hood is in active use.

An object of the present invention is to provide a safety cabinet that allows a clearer observation of contamination of an operation stage surface. In order to realize the object, the safety cabinet is configured to include an operation space including an operation stage; a front panel formed in a front surface of the operation space; an operation opening provided in a lower portion of the front panel; a suction port that is provided in the vicinity of the operation opening on a front side of the operation stage to lead downward; and an air circulation path through which air suctioned from the suction port flows along a lower portion, a back surface, and an upper portion of the operation space, in which the operation stage is made of a transparent material, and a light source is provided to irradiate the operation stage with a light from a side of the operation stage, which is opposite to the operation space.

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.

The present disclosure relates generally to fume hoods, and more particularly to systems and methods for controlling a fume hood airflow using an image (e.g., an optical image, an acoustic image, etc.) of a fume hood opening. A system for controlling a fume hood may include an image capture sensor, a configurator and a controller. The image capture sensor may be positioned to have a field of view that includes at least a portion of a fume hood opening, and may be configured to capture an image that includes at least part of the fume hood opening and/or a person working at the hood. The controller may then provide a control signal to a ventilation device for providing a desired airflow in the fume hood. The control signal may depending on the current size of the fume hood opening as captured by the image capture sensor.

A fume cupboard, of the type comprising a framework with two front uprights (2a,2b), two rear uprights (3a,3b), a rear panel (11), two side panels (6,7), an upper panel (8) and a sash (4) consisting of a frame (12) and at least one panel (13) for closing an inner chamber (10) of said fume cupboard (1). The fume cupboard of the invention comprises a transmission system (14) for transmission of the vertical movements of said sash (4) located inside the abovementioned front uprights (2a,2b), or inside said front uprights (2a,2b) and said rear uprights (3a,3b).

A novel front sash closure for a fumehood of the sort comprising a workspace defined by a frame and accessed by a front opening, the front sash closure comprising: a transparent fixed pane and a transparent hinged pane; wherein the transparent fixed pane is securely mounted to the frame of the fumehood so as to partially cover the front opening of the fumehood, whereby to reduce the size of the front opening of the fumehood to a working opening; and wherein the transparent hinged pane is hingedly mounted to the frame of the fumehood intermediate the working opening so as to be able to selectively cover a portion of the working opening.

The present invention provides a method and kit which can be used to prevent or reduce contaminants in a clean production environment. The method involves providing a processing apparatus having a chamber, and providing a liner within the chamber, wherein a negative pressure is applied to the interior of the chamber to retain the liner against the interior wall of the chamber.

There is provided a safety cabinet in which a good operability is attained and it is possible to secure a sterility assurance level. There is provided a safety cabinet including an operation chamber, a front door that covers part of an opening of a front surface of the operation chamber, an operation opening below the front door, into which an operator can insert an hand and perform an operation, and a front slit, which takes in air inside the operation chamber and air in a room through the operation opening, on a front surface side of a lower portion of the operation chamber, the cabinet including sterilization gas generating means; and sealing means for sealing the operation opening during a sterilization operation.
