Filtri

I filtri sono fondamentali nei laboratori di ricerca e in molti altri settori per rimuovere particelle e creare ambienti idonei a un’ampia varietà di esperimenti e procedure. Questi dispositivi sono disponibili in diverse forme, tra cui filtri in linea, dischi di carta, piccole capsule e grandi pannelli di ventilazione. I filtri inoltre purificano e concentrano i liquidi e i gas necessari per le analisi. Per l’aria, ciò significa eliminare inquinanti, umidità e particelle solide sospese; per i liquidi, rimuovere impurità e piccoli contaminanti.

Ashless quantitative filter papers

Supplier: PRAT DUMAS

The ashless papers are manufactured with a very pure cotton cellulose base. They are purified with acid to reduce the amount of mineral material such as silicon, aluminium or magnesium oxides as far as possible. The residues of the paper after calcination are reduced to negligible quantities and do not affect the results of the qualitative analysis.
