An apparatus including a sensor configured to sense total pressure within an inner chamber of a housing, and to sense differential pressure between the inner chamber of the housing and work area outside of the housing; a computer processor configured to receive signals from the sensor based on the total pressure and the differential pressure; and wherein the computer processor controls the rate at which the flapper oscillates based on the total pressure signal from the sensor, to thereby control the direction of flow of air from the inner chamber of the housing through the plurality of openings of the blade, through the plurality of openings of the teeth, for optimum containment with ultra stable vortex inside the chamber; and controls the rate at which exhaust damper modulates based on differential pressure signal to maintain constant face velocity at the apparatus user opening and out an exhaust opening of the housing.

A metering device for controlled receiving and/or dispensing of one or more media, includes one or more pump unit(s) and one or more control units having at least one signal input device configured to record one or more user input(s). The at least one signal input device includes one or more sensor(s) configured to detect the user input(s) and to convert the detected user input(s) into one or more measured value(s). One or more evaluation unit(s) are configured to control the pump unit(s) as a function of the measured value(s). The user input(s) is/are an action of force of a pressure change (p) effected by a user. In addition, a method for operating the metering device is provided.

Methods, systems, and apparatuses are disclosed for a tamper-resistant collection and retention a chemical sample. In one embodiment, the tamper-resistant system comprises a container operable to collect and retain a chemical sample, a tamper-resistant mechanism operable to disengage at a first chemical sample to allow for a collection of a chemical sample, wherein the tamper-resistant mechanism is operable to record one or more of: a date, a time, and a location, of the chemical sample during the collection of the chemical sample, and wherein the tamper-resistant mechanism is further operable to re-engage and lock after the collection of the chemical sample to resist subsequent chemical samples after the first chemical sampling.

The purpose of the present invention is to provide a clean air device that can reduce the risk of contamination due to static electricity. Provided is a biosafety cabinet or a clean air device that connects a biosafety cabinet and a clean booth, wherein a static eliminator (ionizer) that generates a corona discharge by way of concentrating an electric field on a needle-shaped discharge electrode and eliminates static with ionized air is disposed directly above an air flow branching point where air supplied to a work space branches to the front face and to rear face inside the biosafety cabinet.

A single disposable cartridge for performing a process on a particle, such as particle sorting, encapsulates all fluid contact surfaces in the cartridge for use with microfluidic particle processing technology. The cartridge interfaces with an operating system for effecting particle processing. The encapsulation of the fluid contact surfaces insures, improves or promotes operator isolation and/or product isolation. The cartridge may employ any suitable technique for processing particles.

A microbiology waste containment apparatus and method are provided to prevent toxic slide staining chemicals from being dumped down a drain during slide staining and thus entering publicly owned water treatment works. A primary containment vessel is provided having side walls and an open top area, and a funnel is provided in communication with the open top area. A secondary containment vessel is in fluid communication with the funnel. When microbiology waste is generated above the open top area, the microbiology waste is collected by the funnel and conducted to the secondary containment vessel. The secondary vessel may be disposed internally to the primary vessel, or it may be external to the primary vessel. In the case of the internal secondary vessel, the entire apparatus may be portable and thus appropriate for field or military work.

A safety cabinet has an opening portion in the front surface of a work room and a front shutter and supplies clean air to the work room from above. A side slit is provided in the side surface of the work room, air from the provided side slit joins an air flow path suctioned from a front grille of a workbench forming the bottom surface of the work room, and the turbulence of an airstream can be prevented even when a device is installed in the work room.

A microfluidic device includes an inlet port configured to receive a sample, a first reaction chamber fluidically coupled to the inlet port, a first pump fluidically coupled to the inlet port, a second pump fluidically coupled to a mixing chamber, a metering channel fluidically coupled to the first reaction chamber and to the mixing chamber, and one or more second reaction chambers fluidically coupled to the mixing chamber. The first pump is configured to move fluid from the inlet port to the first reaction chamber and from the first pump to the inlet port. The second pump is configured to move fluid from the second pump to the mixing chamber, from the first reaction chamber to the mixing chamber, and from the mixing chamber to the one or more second reaction chambers.

A tissue processing system for processing a laboratory slide includes a slide holder for holding the slide, an outlet port positioned to direct a fluid stream onto the slide, and a device for moving the slide holder relative to the outlet port, or vice versa, to adjust a point on the slide at which the fluid stream is delivered onto the laboratory slide. The slide holder includes an absorbent pad configured to be positioned between one wall of the plurality of walls and a free edge of the slide for absorbing fluid travelling along the slide. A manifold of the system includes a first outlet port that directs a first fluid stream from a first fluid passageway onto the slide, and a second outlet port that directs a second fluid stream from a second fluid passageway onto a location of the slide that differs from the first fluid stream.
