Ampoules de coulée
Les entonnoirs de coulée gèrent le transfert lent du contenu grâce au robinet intégré. Les bouchons déconnectent l’entonnoir et le bras d’égalisation de pression, laissant les liquides sensibles isolés et non exposés. Typiquement cylindrique, la verrerie de laboratoire est proposée avec ou sans graduations calibrées pour permettre une mesure visible lors de l’ajout de réactifs. Les tiges de goutte protégées ne dépassent pas le rodage conique standard et les joints extérieurs rodés permettent au récipient de s’adapter solidement au ballon de réaction. Les entonnoirs de coulée sont disponibles en différentes capacités.
