摘要:
The invention relates to a device (7) for collecting particles and microorganisms that are present in ambient air, comprising a conical or frustoconical cyclonic chamber (8) for centrifuging air, air-inlet means (16) letting outside air into the chamber (8), and air-outlet means connected by connecting means (19, 20, 21) to air-inlet filters (4) of an individual motorized apparatus (A) for respiratory protection.
摘要:
Device for collecting particles and microorganisms present in the ambient air, comprising air sucking means (14) in a low capacity enclosure (10) wherein particles and microorganisms are centrifugally separated from the sucked air, wherein said device is portable, self-supporting and one-hand handleable, for example with a handle (16) associated with the air sucking means.
摘要:
The invention concerns an immunoassay apparatus, comprising coaxial rotating trays (14) supporting reaction dishes (18) and (16) supporting tubes (24) containing samples to be analysed, means for driving said trays in rotation about a common axis, and means (28) supporting reagents, extending in an arc around said rotating trays.
摘要:
Device for collecting and separating particles and microorganisms present in the ambient air, comprising intake means (36, 38) for taking air into a removable centrifugation chamber (10) forming a container for transporting a liquid specimen containing the collected particles and microorganisms, this chamber being selected from a set of chambers having different diameters corresponding to intake rates of between about 100 and 2000 litres per minute, these rates being achieved with the same intake means.
