PROCESSING SYSTEM FOR POWDERS, AND METHOD FOR DECONTAMINATION OF SUCH A PROCESSING SYSTEM
The disclosure relates to a processing system for in particular pharmaceutical powders, and to a method for decontamination of such a processing system. The processing system includes a processing device for the powder, and a closed housing with an inner production space in which the processing device is arranged. The processing system further includes a steam generator via which water vapor is introduced into the production space in such a quantity that air supersaturated with water vapor develops there at least in some parts. Any powder residues present are bound via water since, on account of the supersaturation, water condenses in the production space. The condensed water, including powder residues bound therein, is removed, in particular with the housing opened.
Apparatus and method to facilitate collecting fluid from wall-mounted appliances
As an example, an apparatus includes a hood portion and a body portion. The hood portion includes a distal opening adapted to be positioned around a periphery of a wall-mounted appliance. The hood portion includes a sidewall of a pliant material extending outwardly from a perimeter of the distal opening to terminate in a proximal opening having a perimeter that is spaced apart from and opposing the distal opening. The proximal opening is to provide access to an interior volume of the hood portion corresponding to the sidewall between the first and second openings. The body portion extends from the perimeter of the proximal opening in a longitudinal direction that is substantially transverse to a central axis of the distal opening. An outlet in fluid communication with the body portion is to enable discharge of fluids from an interior volume of the body portion.
Housing for a laboratory appliance
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.
Laboratory apparatus comprising a UV radiation device, and disinfection method for a laboratory apparatus
The present invention relates to a laboratory apparatus, comprising a UV radiation device which has at least one UV lamp to carry out a disinfection process, and a control device to control the UV lamp, wherein the control device is designed to specify a duration (t) during which the UV lamp is operated during the disinfection process. The control device is designed to specify the duration (t) using a control function stored in the control device as a function of the operating time (d) of the UV lamp, in such a manner that the duration (t) increases with increasing operating time (d). The present invention further relates to a method for operating such a laboratory apparatus.
APPARATUS FOR COLLECTING BY-PRODUCT OF SEMICONDUCTOR MANUFACTURING PROCESS
The apparatus for collecting by-products of the present disclosure includes: a cylindrical housing that has a top plate having a gas inlet and a bottom plate having a gas outlet extending and protruding inside the housing, and receives and then discharges an exhaust gas flowing inside; and a flow path change-type vertical internal collection tower that is installed in a hanging state inside the housing and includes a disc type collector, a diffusion plate, a cylindrical collector, and a cylindrical filter collector for collecting by-products in an exhaust gas flowing inside.
Hood for fume extractor
A removable hood for a fume extractor comprises a shield defining an internal cavity and having one or more vent openings in an upper portion, a welding opening in a rear portion, one or more viewing openings in one or more sides, and a pipe opening in a bottom portion of the shield. The pipe opening comprises arcuate portions on either side thereof for placement adjacent to a pipe. The hood also comprises a removable attachment mechanism on the upper portion of the shield configured to selectively couple the one or more vent openings to an extraction arm of the fume extractor, one or more layers of window material coupled to the shield to cover each of the one or more viewing openings, and one or more internal airflow spaces shaped to direct air flow to cool the window material when suction is applied to the vent openings.
Safety workbench with controlled circulating air flow and method for its operation
The present invention relates to a safety workbench having a work space surrounded by a housing having a work opening located in the housing front side and adjustable with an adjustable front panel for admitting into the work space an air inlet flow, an exhaust blower and a circulating air blower for conveying an air flow in the safety workbench, which are designed such that a partial air flow drawn in by the exhaust blower is filtered through an exhaust air filter as exhaust air flow from the safety workbench and a partial air flow drawn in by the circulating air blower through a circulating air filter as downwardly directed circulating air flow into the work space, and a control device, a differential pressure sensor (16) and two pressure transducers connected thereto which are designed to measure a pressure at two different positions within the safety workbench d, wherein a first of the pressure transducers is arranged in the immediate vicinity of the fan blades on the low pressure side of the circulating air blower and a second of the pressure transducers is arranged in a low-flow area, on the low pressure side of the circulating air blower. The present invention further relates to a method of operating a safety workbench according to any of the preceding claims, comprising the steps of: a) determining a pressure difference between the first pressure transducer and the second pressure transducer by means of the differential pressure sensor, b1) comparing the pressure difference determined in a) with a nominal pressure difference stored in the control device, which corresponds to a nominal volume flow, or b2) converting the pressure difference measured in a) into an associated volume flow and comparing the calculated volume flow with one nominal volume flow stored in the control device, and c) regulating the circulating air blower such that the nominal volume flow is conveyed.
Biological safety cabinet and clean bench
A biological safety cabinet or the like according to an embodiment of the present disclosure includes: a bottom plate 4 provided in a body case 2; and a flexible portion 13 provided to a front shutter protector 6 that is provided to a lower end of the front shutter 5, and is capable of ensure reliability by reducing the load of the front shutter such that outside air is drawn into the body case 2 through a gap 15 formed in a contact portion between the flexible portion 13 and the bottom plate 4.
Weighing fume cupboard with a work surface that is vibrationaly isolated from the rest of the housing
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).
METHOD AND APPARATUS FOR PURGING UNWANTED SUBSTANCES FROM AIR
Apparatus comprising: a fumehood; and an air treatment device for purging unwanted substances from the exhaust air of the fumehood, the air treatment device comprising: a non-thermal plasma reactor stage for producing air byproducts comprising O., N., OH. and O.sub.3 and introducing those air byproducts into the exhaust air of the fumehood so as to treat the exhaust air of the fumehood; and a catalyst stage downstream of the non-thermal plasma reactor stage for further treating the air downstream of the non-thermal plasma reactor stage.
