Abstract:
Appareil de broyage d'échantillons biologiques contenus dans des tubes (12) portés par un plateau (10) entraîné en mouvement oscillant, la zone d'oscillation des tubes (12) étant entourée par des moyens de refroidissement (30) permettant de maintenir les échantillons dans les tubes (12) à une température basse souhaitée, par exemple de 4°C, pendant le broyage.
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:
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.
