Tappi

I tappi solidi a prova di perdite sigillano bottiglie, fiaschi, fiale e persino tubi per impedire la fuoriuscita di liquidi e gas. I modelli multi-foro forniscono le condizioni di stabilità di flusso limitato desiderate per prevenire l'accumulo di bolle d'aria. Con un design leggermente conico, tappi di diversi diametri vengono inseriti negli strumenti da laboratorio per una vestibilità aderente che consente comunque una facile rimozione. Le chiusure sono realizzate in diversi materiali per garantire una resistenza accurata ai contenuti aggressivi e possono mantenere un'atmosfera sotto vuoto.
