A small pore size and slow flow rate make Grade 50 well suited for the retention of very fine crystalline precipitates. Its hardened glazed surface doesn’t shed fibers and can withstand wet handling and precipitate removal by scraping. It’s well suited for:
- Vacuum filtration on Büchner and 3-piece filter funnels
- Carrying integrated circuits
