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.

An airborne pathogen extraction system that provides for continuous airborne pathogen particle extraction from a specifically targeted area in a room or a specifically targeted area proximate to a user. The pathogenic particles are filtered and/or disinfected before the air is returned proximate to the originating location, or are directed an area away from the user(s). The airborne pathogen extraction systems and methods lower the chances of contagion or infection from airborne pathogens, such as viruses.

The invention is an apparatus having a protective envelope which is designed and constructed to envelope at least one room region, such that the protective envelope is able to separate the at least one room region from an environment immediately surrounding the protective envelope, and use thereof. Methods for operating a production engineering unit under cleanroom conditions and for creating and operating a virus-free and cross-contamination free room region surrounded by a protective envelope for accommodating persons and/or objects subject to quarantine. The invention has a protective envelope with at least two layers separated by a spacer layer, that is flow-permeable.

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.

The present invention relates to the field of hygienic ophthalmologic examination. In particular, provided is a slit lamp biomicroscope comprising a laminar airflow device, and methods of using the same.
