A device for collecting and separating particles and microorganisms present in ambient air, the device comprising suction means for sucking air into a removable centrifuging chamber () having an air inlet and outlet and forming a receptacle for transporting a liquid sample containing the collected particles and microorganisms, said enclosure () being selected from a set of enclosures having different diameters and suitable for enabling the same suction means to take samples at suction rates lying in the range about 100 liters per minute to about 2000 liters per minute.

Device for collecting and separating particles and microorganisms present in ambient air

Apparatus for grinding biological samples contained in tubes () carried by a turntable () driven with oscillating motion, the zone in which the tubes () oscillate being surrounded by cooling means () enabling the samples in the tubes () to be maintained at a desired low temperature, e.g. 4&#xb0; C., while they are being ground.

Apparatus for grinding biological samples

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.
