Entonnoirs filtrants

Les entonnoirs de filtration robustes facilitent la collecte des composés solides présents dans les liquides. Les liquides versés sont aspirés sous vide à travers des disques frittés ou des plaques perforées, puis s’écoulent par les longs becs inclinés. Les modèles courants de type Hirsh ou Büchner avec nervures empêchent les blocages d’air et accélèrent l’opération. La résistance chimique et thermique permet aux entonnoirs à cannelures de supporter des matériaux agressifs et des stérilisations répétées. Les modèles varient selon la capacité, la porosité et la taille de papier filtre acceptée.
