Filter

Filter är oumbärliga i forskningslaboratorier och många andra branscher för att avlägsna partiklar och skapa miljöer som är lämpade för en rad experiment och procedurer. Filtren finns i olika former, inklusive inlinefilter, pappersskivor, små kapslar och stora ventilationspaneler. Filter renar och koncentrerar även de vätskor och gaser som behövs för tester. För luft innebär detta att föroreningar, fukt och fasta partiklar avlägsnas; för vätskor innebär det att orenheter och små kontaminanter filtreras bort.
