Abstract:
Apparatus for grinding biological samples contained in tubes (12) carried by a plate (10) which is oscillated, wherein the tube (12) oscillation zone is surrounded by cooling means (30) for keeping the samples in the tubes (12) at a desired low temperature, for example of 4°C, during the grinding.
Abstract:
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.
Abstract:
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.
Abstract:
A device for collecting particles and microorganisms present in ambient air, the device comprising means for sucking air into a small volume enclosure in which the particles and microorganisms are separated from the sucked-in air by centrifuging, the device being portable, self-contained, and capable of being handled in one hand only, e.g. by means of a handle associated with the air suction means.
Abstract:
Dispositif de collecte de particules et de micro-organismes présents dans l'air ambiant, comprenant des moyens (14) d'aspiration d'air dans une enceinte (10) de faible volume dans laquelle les particules et micro~organismes sont séparés de l'air aspiré par centrifugation, ce dispositif étant portable, autonome et manipulable d'une seule main, par exemple au moyen d'une poignée (16) associée aux moyens d'aspiration d'air.
