Imbuti per filtrazione
Gli imbuti di filtrazione per uso intensivo facilitano la raccolta dei composti solidi presenti nei liquidi. I liquidi versati passano per aspirazione sotto vuoto attraverso dischi fritti o piastre forate e fuoriescono attraverso lunghi steli inclinati. I comuni modelli Hirsh o Büchner con nervature evitano il blocco d’aria e rendono l’operazione più rapida. La resistenza chimica e termica consente agli imbuti filtranti plissettati di gestire materiali aggressivi e cicli di sterilizzazione ripetuti. I modelli variano in capacità, porosità e formato di carta da filtro supportata.
