Abstract

La présente invention concerne un appareil à chambre pour expériences de rejet de produits polluants, qui est utilisé pour prélever de petits échantillons de produits, par exemple des articles pour enfants. L'appareil à chambre pour expériences de rejet de produits polluants comporte une partie de chambre formée dans une partie de corps principal et un revêtement intérieur, capable de recevoir un échantillon de produits de manière remplaçable, disposé dans la partie de chambre de telle façon que des substances nocives contenues dans l'échantillon de produit puissent être mesurées après que l'échantillon de produit a été recueilli et reçu par le revêtement intérieur. Il est ainsi possible de réaliser une mesure précise sur un produit ou un échantillon de petite taille. De plus, comme le revêtement intérieur inséré dans la partie de chambre présente une forme qui permet son insertion et son retrait, le revêtement intérieur ainsi que des premier et deuxième conduits de raccordement sont formés de telle façon que la partie de corps principal et la partie de chambre formée dans la partie de corps principal ne soient pas exposées à la substance nocive.
