General description
Especially useful where filter paper would be attacked by filtered material.Sintered discs with max. pore sizes in the range 40 to 100 µm are often used for preparative work and mercury filtration, 16 to 40 µm discs for analytical work with medium precipitates and 10 to 16 µm for fine precipitates. 1.0 to 1.6 µm discs are for ultra-fine filtration of biological solutions as they remove bacteria from liquids that would decompose if heated.Porosity chart for Duran filter funnels:Grade 2: 40-100 µm nominal max. pore sizeGrade 3: 16-40 µm nominal max. pore sizeGrade 4: 10-16 µm nominal max. pore sizeGrade 5: 1.0-1.6 µm nominal max. pore size
