Filtre

Filtre er vigtige i forskningslaboratorier og mange andre industrier for at fjerne partikler og skabe miljøer, der fremmer et bredt udvalg af eksperimenter og procedurer. Avantor forhandler og vejleder i alt omkring filterpapir, membranfiltre, sprøjtefiltre, glasfiberfiltre, bottle top filtre og meget mere.

Enhederne kommer i forskellige former, herunder in-line filtre, papirskiver, små kapsler og store ventilationspaneler. Filtre renser og koncentrerer også væsker og gasser, der kræves til testning. For luft betyder det at fjerne forurening, fugt og faste luftbårne partikler, mens det for væsker betyder at fjerne urenheder og små forurenende stoffer.
