U hebt gezocht naar: Filtertrechters
Zware filtratietrechters helpen bij het opvangen van vaste stoffen die aanwezig zijn in vloeistoffen. De gegoten vloeistoffen worden door vacuüm via sinterschijven of geperforeerde platen geleid en stromen uit via lange, schuine stelen. Veelvoorkomende Hirsh- of Büchner-modellen met ribbels voorkomen luchtblokkades en versnellen de werking. De chemische en thermische bestendigheid maakt het mogelijk om gefelste trechters te gebruiken met agressieve stoffen en herhaalde sterilisatie. Modellen verschillen in inhoud, porositeit en grootte van passend filterpapier.
