Entonnoirs
Les entonnoirs facilitent le transfert de liquides ou de poudres dans des récipients. Généralement dotés d’une large ouverture permettant d’acheminer les substances vers une tige étroite, ils empêchent les déversements et maintiennent un espace de travail propre. Les entonnoirs existent en versions spécialisées pour des applications de laboratoire spécifiques. De nombreux modèles sont compatibles avec du papier filtre ou une friture en verre pour la filtration. Grâce à leur capacité à canaliser des matériaux fins ou liquides, les entonnoirs sont des outils essentiels dans tout environnement.
