A biosafety cabinet includes an operation, an operation space, a front plate, an operation opening, a vibration damping mechanism and an exhaust. The vibration damping mechanism is a mechanism that floats an operation object, which is disposed in the operation space, from the operation stage. The vibration damping mechanism includes a table which supports the operation object, and a magnet which is disposed in the operation stage. The vibration damping mechanism is a mechanism that floats the operation object from the operation stage by using a magnetic force.

A method is provided for detecting primary gas flows (18) in flow chambers (10). The primary gas (18) flowing in a flow chamber (10) is locally seeded with a seed substance and the movement of the seed substance, representative of the flow of the primary gas (18), is detected by imaging by an image detector (28) and an imaging optics (30) arranged in front of said image detector (28). A gas mixture (34) that moves along with the primary gas (18) without relative motion and that has a refractive index distinguishable from that of the primary gas (18) is used as the seed substance, and imaging detection is carried out by a background schlieren measurement method.

In order to aspire to higher sensitivity in an automatic analysis device, it is important to prevent the mixing of dust and the like in a reaction part in which a sample and a reagent react. The present invention presents an automatic analysis device that is provided with a configuration for making the pressure inside a specific block in the device such as a reaction part, or inside the device become positive. By making the pressure become positive and forming an air flow that flows out from the inside of the reaction part or the device, it is possible to limit, to a certain amount or less, the amount of dust penetrating into the reaction part.

Methods of selectively positioning a micro-object in a microfluidic device are described in this application. The microfluidic device can comprise an enclosure having an inlet, an outlet, and a flow region connecting the inlet and outlet, and an electrode activation substrate having a photoconductive layer. The methods of selectively positioning can comprising: projecting a first light beam on an electrode activation substrate of the microfluidic device, wherein the first position is proximal to the first micro-object, and wherein the first light beam activates a positive dielectrophoresis (DEP) force within the enclosure sufficient to capture the first micro-object; and projecting a second light beam upon a second position on the electrode activation substrate, wherein the second position is adjacent to or at least partially surrounding the first position, without overlapping the first position, the second light beam activating a positive DEP force within the enclosure sufficient to capture second micro-objects other than the first micro-object. The methods of selectively positioning can further comprise moving the first light beam towards a third position on the electrode activation substrate, wherein the DEP force activated by the first light beam is sufficient to move the first micro-object to the third position. Optionally, the methods can include moving the second light beam in relation to the first light beam to prevent micro-objects other than the first micro-object from being captured by the first light beam. Other embodiments are described.

A technique is provided whereby hydrogen peroxide introduced into a working chamber containing a resin component is reduced to a low concentration in a shorter time than before. The present invention resides in a method of maintaining a sterile environment of a working chamber that contains a resin component, and includes a step (a) of introducing hydrogen peroxide into the working chamber, a step (b) of introducing air into the working chamber through a filter after completion of the step (a), a step (c) of generating ozone by irradiating the air with ultraviolet having a peak wavelength of from 160 nm to less than 200 nm upstream of the filter or inside the working chamber and introducing the ozone into the working chamber, and a step (d) of decomposing the ozone introduced into the working chamber into oxygen radicals.

A passthrough for a barrier separating a first space from a second space includes a housing mounted to an opening that extends through the barrier. First and second doors selectively block the first and second spaces, respectively, from the opening. A frame is disposed within the housing and has first and second apertures configured to receive sealing blocks. When the passthrough is in a first state, sealing blocks seal the first and second apertures. When the passthrough is in a second state, a fluid conduit passes through the first and second apertures and sealing blocks seal the space between the first and second apertures, respectively, and the conduit.

A work glove is installed at the port flange, with the result that the operator can enter the working chamber of the containment in a protected manner. A multiplicity of port flanges are usually mounted on the containment and a work glove is fastened in each case to the respective port flange. Machinery for processing material to be treated is often set up in the working chamber. In order to temporarily block the access, a shut-off part which can be moved into a blocking position and an open position is provided. In order to record personal data relating to the operator, the arrangement has a capture unit which has a connection to a microcontroller.
