Cytiva Whatman™ Grade 50 Quantitative Filter Paper, Hardened Low Ash
Cytiva's Whatman™ Grade 50 quantitative hardened low ash filter paper is highly glazed to enable recrystallization of very fine precipitates using Büchner funnel or Hirsch funnel filtration. This hard, very thin, high wet-strength Grade 50 quantitative filter paper withstands wet handling and precipitate removal by scraping. With very minimal fiber shedding, they are an especially good choice for use as carriers in integrated circuits.
